Stainless Steel 304L Pipe

SA 312 TP304L Pipe is one of the widely used grades of stainless steel made pipes in the Oil and Gas Industry. The 304 material has high strength and considerable corrosion resistance. The material is also cheaper than many other alloys and it is cost effective to use. The Stainless Steel 304L Pipe is a lower carbon version of the 304 material. The lower carbon content enables easy welding and reduces the localized corrosion. Also, the SS 304L Seamless Pipe is tougher and has high wear and tear properties.

Metallon Pipings FZ LLC is a exporter and supplier of various grades and specification of 304 Pipe such as the ASTM A554 TP304L. The application of these tube could be seen in the food processing, chemical processing, petroleum, oil and gas and in power generation industries. Our INOX 304L Pipe products are made of high quality standards. We manufacture the ASTM A270 TP304L tube under the standards and test them with international quality. There are electric resistant welded and the SS 304L seamless pipe available in this grade. The welded ones are stronger but the seamless ones are more precise in dimensions. You can get the 304L SS sanitary pipe and other specific application tubes from us. Please make an inquiry about your product needs with us. Metallon Pipings FZ LLC can supply Stainless Steel 304L Pipe to Saudi Arabia, Malaysia, Indonesia and MENA countries within 7 Days. Also export AISI 304L Seamless Pipes in Netherlands, USA, South Africa, Abu Dhabi and Qatar from ex-stock.
