Many industries depend on piping systems designed for challenging conditions like high pressure and temperature fluctuations. Flexible stainless steel pipes offer essential durability and adaptability within these demanding settings. Knowing the top suppliers helps ensure access to reliable solutions for critical infrastructure.
Stainless steel flexible pipe is essentially a bendable tube made from corrosion-resistant steel, often with ridged, corrugated walls. Its primary advantage lies in connecting components that might move, vibrate, or not line up perfectly. Many versions include an external steel braid, which increases the pipe’s ability to withstand pressure.

Company Description
Jianglin Steel, officially Tianjin Jianglin Technology Development Co., Ltd., is located in Tianjin, China, and started up in June 2003. Its founder, Wang Junjiang, didn’t just start the company; he helped get the Tianjin Metal Material Industry Association going too. This helped the local steel businesses work together better, more like a team, you see.
It started with a good chunk of money, 500 million RMB. Since then, the company has grown quite a bit and does more than just one thing now. The main office? That’s in Yuanjiabao Village, in Tianjin’s Wuqing District.
The factory building is around 21,000 square meters large. Plus, it’s only like 40 minutes away from Tianjin Port. That location is super helpful for shipping things out to other countries.
Jianglin Steel really focuses on making good stainless steel flexible pipes. That’s a big part of their business, a core product line.
These pipes meet standards like ASTM A554, A269, and A312 – those are international rules. They make pipes for tough industrial jobs and also decorative ones, the kind that look nice. Flexible pipes are great when things need to bend, handle shaking, or fit in tight spaces. Very useful stuff.
They’re careful about quality when making these flexible pipes, it seems quite important to them. Each pipe gets checked with water pressure. They even use X-rays to be sure the welds are strong and won’t fail.
You’ll find markings on every pipe too. These marks tell you about the standards the pipe meets. It shows the company stands behind its quality for the customer.
Jianglin offers these stainless steel flexible pipes in lots of sizes. The outside measurement, the diameter, goes from 20mm all the way to 1000mm. Wall thickness? That can be from 0.5mm to 8.0mm, quite a range. They make both welded and seamless pipes, so you can pick the type that fits the specific job you have.

Company Description
Unisource Manufacturing Inc., located in Portland, Oregon, got its start way back in 1980. The whole point then was to shake things up in the industrial hose world – better manufacturing, quality stuff, smarter engineering, you get the picture. They wanted to bring fresh ideas for flexible pipes to all sorts of industries.
You’ll find the main office in Portland, Oregon. They also have another warehouse over in Los Angeles, California. Their main factory is huge, something like 130,000 square feet just for making, assembling, stocking, and testing everything out. It definitely helps make them one of the bigger names for flexible metal hose around North America.
A big part of their business is stainless steel flexible pipe. It’s kind of their bread and butter. They have different kinds, like the Superflex series. This one uses an inner hose made of Type 321 or Type 316 stainless steel, shaped by machines. You can choose one or two braided layers outside, it just depends on the pressure needed.
Need something tougher for really high pressure? Check out the Superflex HD line. HD means Heavy Duty. These pipes have a thicker wall and a tight build, which handles more pressure but still bends when needed. Oh, and then there’s Ultraflex. They say it’s about the most flexible hose you can find anywhere because it’s hydroformed – shaped with water – making it last a long, long time. It’s even got an ISO 10380 certification.
These stainless steel pipes from Unisource are made to fix common headaches in plumbing or factories. Like, stopping shaking, quieting noise, or keeping things safe during earthquakes. Pipes that don’t quite line up? Or pipes that get longer or shorter with heat changes? These flexible connectors help with that too. Most times, the braided layer on the outside uses Type 304L stainless steel.

Company Description
Duraflex Inc., located in Cary, Illinois, makes carefully designed flexible parts, mainly focusing on stainless steel flexible pipes. The company got its start back in 2004. Dean DellaCecca founded it because he wanted an independent business that was really good at making quality flexible piping. Duraflex is still operating out of Cary.
You’ll find the main office at 765 Industrial Drive in Cary. Duraflex actually expanded there too, adding a second building—about 26,000 square feet—to handle more work as the business grew. Being in Cary helps with shipping things out easily, plus keeps the company tied to the local area.
What Duraflex is known for is custom-made stainless steel flexible pipes. These are built for tough jobs across different industries. Their pipes and hoses use good materials and careful manufacturing steps. This ensures they work well and hold up over time.
These parts are made to handle specific problems. Things like soaking up shaking, dealing with pipes getting hot and expanding, or just adding some bendiness where pipes are usually stiff. Making sure they can do all that is important.
The company knows a lot about stainless steel. That’s a big plus. They use different kinds of stainless steel to make flexible piping that works even under tough conditions – think high pressure, really hot temperatures, or where chemicals might cause rust. These stainless pipes are built strong but stay flexible.
Duraflex takes pride in its engineering know-how and the way it makes custom items. They don’t just sell off-the-shelf parts. Instead, Duraflex works with customers to figure out and build the exact stainless steel flexible pipe solution needed for a specific job. The engineering team helps out through the whole process, design to manufacturing, making sure everything is built just right.
A key thing they make is multi-ply stainless steel bellows. These are made from thin sheets of stainless steel but are designed to be tough and bendy. That makes them good for equipment that starts and stops a lot, or in places with lots of vibration, helping critical connections last longer.

Company Description
McGill Hose & Coupling, Inc. is located in East Longmeadow, Massachusetts, and it’s a family-run business even now. Harry A. McGill kicked things off way back in 1962. It was first called H.A. McGill Company, but they changed the name in 1965 so people knew it was all about hoses and couplings.
The business definitely didn’t stay small; it grew quite a lot over time. Today, you’ll find three McGill spots in the Northeast: the main headquarters still in East Longmeadow, another in East Providence, RI, and one up in Woburn, MA. All that space adds up to over 125,000 square feet for keeping parts, building things, and running the offices.
A really big focus for McGill Hose & Coupling is stainless steel flexible pipe. Sometimes people call it a stainless steel braided hose. This type of pipe is great because it can handle super hot or cold temperatures and lots of pressure. It also makes connections that won’t leak gas, which is pretty important for certain jobs.
McGill keeps a whole lot of this stainless steel pipe ready to go. You can get it in sizes from tiny 3/16-inch diameters up to big 8-inch ones. They’ve got different metal mixes, pipes rated for different pressures, and choices for how much you need the pipe to bend.
Making custom items is something McGill does really well, it’s a key part of their work. The workshops are set up in special sections called “pods.” Metal hose making happens in its own area, separate from other tasks, so the workers get really skilled at that specific job.
The company employs welders certified to an official standard, ASME IX B31.1, which shows they know their stuff. These welders build custom stainless steel flexible pipe setups just for what the customer needs. It could be replacing a part from the original maker, figuring out a better way instead of a clumsy setup, or solving a tricky problem with moving fluids around.
Comflex Industrial Co., Ltd.
Year Founded: 2014
Main Products
- Stainless steel corrugated flexible metal hoses
- Flexible exhaust pipes
- Metal expansion joints
- Stainless steel flexible metal conduits

Company Description
Comflex Industrial Co., Ltd., based in Wuxi, Jiangsu, China, operates as a prominent maker of flex-related items. The company got started back in 2014. Since then, it’s become a well-respected name in China for stainless steel flexible pipe solutions. Comflex really aims to be a top supplier of quality metal hoses and the machines to make them, focusing hard on those stainless steel flexible pipe products.
You’ll find the company’s main office and its factory in the Wuxi National Hi-tech Industrial Development Zone. That’s in Jiangsu Province. Being there has helped Comflex build up a pretty big global distribution network. It ships products to over 50 countries spread out across six continents.
Their international customers are all over, places like Europe, North America, Asia, Australia, and South America. They do a lot of business in countries like Russia, Ukraine, Australia, Brazil, and Venezuela specifically.
Kelly Huang is the manager who handles the international business side of things. With Huang leading, Comflex got good at several ways to make stainless steel flexible pipes. They know how to do mechanical forming, hydraulic forming, and even elastomer forming processes.
The stainless steel flexible pipes Comflex makes are useful in lots of different industries because they’re quite versatile. The corrugated stainless steel pipes have these ring-like ridges, called annular corrugations. These give the pipes great flexibility but still keep them strong enough to handle pressure.
Comflex makes these pipes in different sizes, from small ones about 8mm across to much larger ones at 400mm. The walls of the pipes are between 0.2mm and 1.2mm thick. This range lets them handle working pressures anywhere from 8 to 90 bar.
Most often, the pipes are made using SUS304 stainless steel (that’s also called AISI 304). This material is good because it resists rust and corrosion well and can withstand temperatures up to 800°C. If a job needs something extra, maybe better heat resistance or even more corrosion protection, the company also uses SUS321 and SUS316L steels. But that SUS304 grade? It usually gives the best mix of being easy to work with, lasting a long time, and not costing too much, which is why it’s the most common choice.
Conclusion
Selecting the appropriate flexible stainless steel pipe requires matching product capabilities with specific application needs. Working with established suppliers helps guarantee that components meet necessary quality and performance standards. This careful approach results in more dependable and longer-lasting industrial piping systems.
