3 Inch Seamless Stainless Steel Round Pipe Grade 304/316
Stainless Steel Seamless Pipe Description
Stainless steel pipe is a key component in pipeline systems used to transport fluids, gases and solids. It is widely used in chemical industry, petroleum, pharmaceuticals, food processing, building decoration and other fields.We offer our range of stainless-steel tube (or pipe, pole, piping, tubing, as it is also often referred to as) in steel grades 304 and 316.
Grade 304 is the most used standard grade has good corrosion resistance and good machinability.
316 Grade has much better corrosion resistance and is the grade recommended for marine environments or coastal applications,also known as "marine grade"
