Our customers cover more than 45 countries including Italy， UK， Germany， USA， Canada， Chile， Colombia， Saudi Arabia， South Korea， Poland， Singapore， Australia， France， etc.
说明
Grade 316L is a low carbon version of 316 stainless steel. When cold worked， 316 can produce high yield and tensile strengths similar to duplex grades.
It is commonly used in the chemical and petrochemical industries， food processing， pharmaceutical equipment， medical devices， drinking water， wastewater treatment， marine applications and construction applications close to coasts or urban areas.
These are highly resistant to chloride corrosion， so 316l stainless steel pipes are resistant to pitting and crevice corrosion even in chloride-rich environments. Our stainless steel pipe 316l seamless products can be used in marine， marine applications， sea water purification systems， and wastewater management applications. There are different pipe schedules to accommodate different diameters and wall thicknesses. Stainless Steel Tube 316l Schedule 40 is a medium pressure vessel capacity， while Stainless Steel Tube 316l Schedule 10s has a relatively small wall thickness. Our 316l Schedule 40 pipe is one of the most commonly used pipes in the oil and gas industry. Our resistance welded SS 316l Erw tubes are stronger and last longer. The advantage of 316l welded pipe is that it is easy to weld with or without filler material. We also offer square tube 316l for extra strength in structural applications.
