Stainless steel welded pipe can be used in virtually every industry thanks to its flexibility. However, they fare better in corrosion resistance as opposed to withstanding pressure. Because of the materials used and the lightweight nature of welded pipes, they’re far more cost-effective than most other piping methods and offer the best value for your money.

Our staff are qualified and certified according to all current welding procedures, thus guaranteeing our customers longitudinally welded stainless steel pipes in line with the requirements.
● Stainless steel contains chromium which provides the properties of corrosion resistance at high temperatures.
● Stainless steel can withstand corrosive or chemical environments due to its smooth surface.
● Stainless steel products are safe for long-term use with excellent resistance of corrosion fatigue.

Welded stainless steel tubes have rust resistance and excellent high temperature resistance.

Stainless steel welded pipe is corrosion resistant and this type of material is extremely durable in harsh conditions. This type of pipe is popular in industrial applications in the following industries:
● Chemical
● Food and beverage
● Marine
● Mining
● Oil and gas
● Pharmaceutical
● Petrochemical
● Power generation
● Renewable energy
Stainless steel welded pipe can be cheaper to manufacture than seamless pipe for your applications that require corrosion resistance.
