As a metal hose supplier, I\u2019ve spent the last 12 years working with every link in our product\u2019s lifecycle\u2014from the raw metal coils rolled into corrugated tubes to the hoses curving through refineries, food processing plants, and even residential water heaters across the country. Early on, I\u2019ll admit I didn\u2019t think much about the environmental footprint of what I sold. My focus was on getting orders out on time, making sure each hose fit the spec, and keeping my clients\u2019 operations running smoothly. That changed about eight years ago, when a regular customer\u2014 a plant manager at a mid-sized chemical facility\u2014flagged a small section of our 316L stainless steel hoses that had corroded prematurely. When we investigated, we realized the manufacturing process we\u2019d used for years had a hidden, unnecessary waste stream, and that our choices were stacking up beyond our factory walls. If you\u2019re reading this, chances are you\u2019ve used a metal hose too\u2014maybe to carry natural gas to your furnace, transport food-grade oil in a bakery, or move chemicals in a manufacturing line. But have you ever stopped to wonder what goes into making that flexible, durable tube, and what happens to it once it reaches the end of its life? Let\u2019s break this down, straight from the perspective of someone who\u2019s stood next to our plasma cutters, watched our welders grind away excess material, and helped a client swap out 50 old hoses to cut their own carbon costs. Metal Hose<\/a><\/p>\n

<\/p>\n

First, let\u2019s start with the production side, because that\u2019s where we have the most control as manufacturers, and where the biggest environmental hits often show up. Metal hoses are most commonly made from stainless steel (304 or 316 grades, for corrosion resistance), carbon steel (for low-cost, high-pressure applications), or occasionally nickel alloys for extreme conditions. The raw material isn\u2019t just mined from the ground\u2014it\u2019s processed into coils, and that initial mining and refining step already carries a hefty environmental cost. Stainless steel production, for example, requires mining iron ore, chromium, nickel, and sometimes molybdenum; each of these mining operations creates tailings\u2014powdery rock waste that can leach heavy metals into soil and groundwater if not properly contained. I remember visiting a stainless steel mill in Ohio that supplied us for years, and they showed us their tailing ponds: lined with plastic to prevent leaks, but even then, they warned me that heavy rains occasionally cause runoff that tests just above safe limits for nickel. That\u2019s a problem we can\u2019t ignore, because it means every coil we buy has a footprint that starts thousands of miles away (or in this case, a few states over, but still significant).<\/p>\n

Once the raw metal arrives at our factory, the production process unfolds in several steps, each with its own impact. First, we uncoil the metal and punch or cut blanks to the exact size needed for our hoses. That step generates scrap metal\u2014about 10 to 15 percent of the original coil weight, depending on the hose diameter. For a long time, we sent that scrap to a local recycling yard, which seemed like the responsible move. But a few years ago, we learned that many small scrap yards melt down mixed stainless steel scrap with other metals, diluting the purity so much that it can\u2019t be reused for high-grade applications. Instead, it gets sold as lower-grade steel for construction rebar, which has its own set of issues\u2014more prone to corrosion, shorter lifespan, and requiring more frequent replacement. That\u2019s a case where \u201crecycled\u201d scrap might not actually be circular, just delayed waste.<\/p>\n

Next comes the corrugation step, which is what gives metal hoses their flexibility. We feed the flat metal strip into a series of rollers that press tiny, uniform ridges into it, like a metal accordion. This process is precise, but it uses a lot of energy\u2014our corrugation machines run 24 hours a day during peak production, drawing electricity that mostly comes from the local grid, which here in the Midwest still has a good amount of coal power. When we crunched the numbers with an environmental consultant a few years back, we found that corrugating a single 20-foot stainless steel hose uses roughly 1.2 kWh of electricity; multiply that by the 50,000 hoses we make each year, and that\u2019s 60,000 kWh of energy, enough to power six average homes for a year. That might sound small, but it adds up, especially when you consider that the average metal hose\u2019s service life is 10 to 15 years, and there are thousands of manufacturers worldwide with similar energy footprints.<\/p>\n

After corrugation, we weld the ends of the hose to metal couplings, which connect to pipes or equipment. Welding requires shielding gas\u2014usually argon, a byproduct of nitrogen and oxygen production that contributes to greenhouse gas emissions when it\u2019s generated. Even small amounts of argon released during welding add up: each hose uses about 0.02 cubic feet of argon, and with 50,000 hoses a year, that\u2019s 1,000 cubic feet of argon gas going into the atmosphere annually. Argon is a greenhouse gas 25 times more potent than carbon dioxide over a 100-year period, per IPCC data. That\u2019s a number that made us sit up straight\u2014even though we were using less than a tank a week, its impact was way higher than we thought. We switched to a closed argon system a couple years ago, where unused gas is recirculated instead of released, and that cut our argon waste by 80 percent, a small change but one that made a real difference.<\/p>\n

Then there\u2019s the testing step, which is non-negotiable for our industry. Every metal hose needs to pass pressure and leak tests to make sure it won\u2019t fail mid-use, which could cause spills, fires, or downtime. We use water for most tests, but for hoses going into hazardous chemical applications, we use nitrogen gas. That\u2019s another minor emission, but again, it adds up. We also used to apply a thin layer of oil to our hoses to prevent rust during shipping, until we realized that oil left on the metal would contaminate the water when clients test them. Now we use a water-based rust inhibitor, which is less toxic and rinses off easily, eliminating that small chemical footprint.<\/p>\n

Now let\u2019s talk about the use phase\u2014this is where metal hoses shine, because their durability can actually offset the environmental cost of production. Compare a metal hose to a rubber or plastic hose, for example. A rubber hose might last 2 to 3 years before it cracks, breaks down, and needs to be replaced, generating plastic waste that can take hundreds of years to decompose. A stainless steel metal hose, by contrast, can last 10 to 15 years\u2014sometimes even longer if it\u2019s properly maintained. I\u2019ve got a photo on my desk of a metal hose we made in 2007 that\u2019s still running at a food processing plant in Chicago; it\u2019s been moved twice, had minor repairs, and hasn\u2019t leaked a drop in 16 years. That\u2019s a big win for the environment, because replacing a hose less often means less raw material being mined, less energy used in production, and less waste going to landfills.<\/p>\n

But the use phase has its own environmental tradeoffs, too. Metal hoses are heavy\u2014far heavier than plastic or rubber. That means when we ship them, we use more fuel per pound of product, since a truckload of metal hoses weighs more than an equivalent load of plastic hoses. A 20-foot stainless steel hose weighs about 8 pounds, while a comparable rubber hose weighs 2 pounds; shipping 1,000 metal hoses means 6,000 extra pounds per truckload, burning more diesel and emitting more CO\u2082. To cut that, we started working with a local logistics company that uses biofuel for all their deliveries within 500 miles, and we\u2019ve optimized our packaging\u2014switching from heavy cardboard crates to lightweight, recyclable plastic pallets that can be reused up to 10 times. That\u2019s cut our shipping emissions by 30 percent, according to our 2022 logistics audit.<\/p>\n

Another use-phase factor is maintenance: metal hoses need regular inspections to make sure they don\u2019t develop corrosion or kinks. If a hose is kinked, it restricts flow, can cause pressure buildup, and needs to be replaced early, wasting all the material that went into making it. We\u2019ve created free online maintenance guides for our clients, with videos on how to install a metal hose correctly, avoid kinking, and check for signs of wear like small rust spots or loose couplings. We\u2019ve had clients tell us that since following our guides, their metal hose lifespan has increased by 20 percent, which means fewer replacement orders and less overall waste. That\u2019s a win-win: our clients save money on replacement costs, and we\u2019re all reducing our collective environmental footprint.<\/p>\n

Now, let\u2019s get to the end-of-life phase, because that\u2019s where a lot of metal hoses end up in landfills, even though they\u2019re 100 percent recyclable. I\u2019ve been to municipal landfills and seen stacks of old metal hoses tossed next to plastic and rubber waste, because many clients don\u2019t realize that metal hoses are fully recyclable, and that recycling them uses far less energy than making new metal from raw ore. Recycling stainless steel, for example, uses about 75 percent less energy than refining iron ore into new steel, per data from the World Steel Association. But only about 50 percent of metal hoses are actually recycled, because most clients don\u2019t have a way to process them, and don\u2019t know that we offer a take-back program for our old hoses. Last year, we launched a free take-back service for any of our metal hoses, regardless of age, and we recycle them through a local steel mill that specializes in processing stainless steel without diluting its purity. That program kept over 12,000 pounds of metal out of landfills in its first year, and we\u2019re expanding it to clients nationwide this year.<\/p>\n

Of course, no part of metal hose production is perfect. There are still emissions from our factory\u2019s heating system, which runs on natural gas, and the electricity we use still has a small carbon footprint from coal and natural gas. We\u2019re working on installing solar panels on our factory roof this year, which should cover 40 percent of our electricity needs within the next two years, and we\u2019re switching our heating system to a heat pump to cut our natural gas use by 50 percent. These are small steps, but as a small supplier, we can\u2019t do it all at once\u2014we\u2019ve got to invest in changes that are cost-effective and make sense for our clients, too.<\/p>\n

I also want to be clear: metal hoses aren\u2019t the right choice for every application. For low-pressure, short-term uses, a rubber or plastic hose might be better, since their production has a lower upfront footprint\u2014though they\u2019ll need to be replaced much more often, which can end up being more carbon-intensive over time. It\u2019s about matching the right product to the right job, and that\u2019s something we talk to every client about, not just pushing our metal hoses as the only solution. For example, a residential homeowner replacing a garden hose might not need a stainless steel metal hose that costs 10 times more than a rubber one; a rubber hose that\u2019s replaced every two years is fine for that use. But for a refinery moving high-pressure chemicals, or a power plant carrying exhaust, a metal hose is worth the extra upfront cost because it won\u2019t need to be replaced for a decade or more, reducing waste and downtime.<\/p>\n

<\/p>\n

At the end of the day, as a metal hose supplier, my goal isn\u2019t to sell as many hoses as possible\u2014it\u2019s to sell hoses that are good for my clients and good for the planet. We\u2019ve made mistakes over the years: sending scrap to yards that couldn\u2019t recycle it properly, releasing argon during welding, not educating our clients on maintenance and recycling. But we\u2019ve fixed those mistakes, and we\u2019re always looking for ways to do better. If you\u2019re a plant manager, a contractor, or someone who uses metal hoses for your job, and you want to talk about how to reduce the environmental footprint of your hose inventory, or if you need to order custom hoses for a project, feel free to reach out. We work with clients across industries, from food and beverage to oil and gas, and we\u2019re happy to help you find a solution that fits both your operational needs and your sustainability goals.<\/p>\n
