316L seamless stainless steel pipe is manufactured as per ASTM A312 TP316L standard with low carbon content. The 316 material is made up of chromium nickel alloy with the addition of molybdenum to the composition. This combination makes the material corrosion resistant to most hostile conditions. The Stainless Steel 316L Pipe is easy to weld upon and it is one of the most used stainless steels next to the 304 steel. The applications range from domestic to high end industrial applications. The material is especially corrosion resistant to chloride ion rich environments so that it is used mostly in the sea water desalination plants, water supply lines and in marine applications.
The Stainless Steel 316L Seamless Pipe produced by us is of high quality. We test the products according to international standards and supply to a very large customer base. Metallon Pipings FZ LLC is also one of the leading stockiest and supplier or the ASTM A554 TP316L Pipe in Sch5 to Schedule 80 and thicker wall thickness. There are different nominal sizes in the ASTM A270 TP316L range and we produce them all. There are different manufacturing methods and types of the UNS S31603 Pipe as well. You can buy the SS 316L seamless pipe or the welded tubes from us in any desired requirements. We export Mirror Finish SS 316L Pipe in Houston, Dammam, Nigeria, Rotterdam, Amsterdam, Abu Dhabi, Dubai, Malaysia and Doha as per MIL-T-8973.
