ASTM A312 TP316l stainless steel seamless pipe with flange is a welded combination of pipe and flange, and short pipe is a combination of pipe parts, prefabricated in the pipe workshop for on-site installation. Usually flange connection is used to facilitate connection with other short pipes. HT PIPE 316L seamless SS pipe manufacturer will manufacture these spools and provide complete packaging as per customer’s requirement. We can also provide mobile containerized prefabrication workstations, including pipe cutting, beveling, assembly and welding modules, to make on-site prefabrication easier.

 

Our ASTM A312 316L stainless steel pipe with flange is made of 316L stainless steel. ASTM A312 316L is a derivative of 18-8 austenitic stainless steel. Its main components are chromium, nickel and molybdenum, and 2% to 3% of Mo is added. UNS S31603 seamless pipe has good corrosion resistance in general environment, especially in chloride environment, and can resist the erosion of seawater, hydrochloric acid and other chemical substances. The carbon content of DIN 1.4404 Pipe is lower than that of 316 stainless steel pipe, about 0.03%, while the carbon content of 316 stainless steel pipe is about 0.08%. This means that DIN 1.4435 Pipe has better corrosion resistance and higher resistance to intergranular corrosion.

ASTM A312 TP316l stainless steel seamless pipe with flange

Pre-fabrication pipe spools welding is to cut the original pipes to the required size, and move them to the assembly table for welding together with the pipe fittings. Our pipes and flanges are all guaranteed materials and production standards. SS 316l seamless pipe conforms to ASTM A312/ASME SA312 international material standard, and the production standard is ASME B36.19. When selecting flanges for ASME SA312 Grade 316L pipe, it is important to consider material compatibility, size and pressure rating, the flange must also comply with relevant standards and codes such as ASTM A182 or ASME B16.5.

 

The advantages of prefabricated welded stainless steel pipe with flange include:

High welding quality: The production process of ASTM A312 TP316l stainless steel seamless pipe with flange adopts professional equipment and technology, which can ensure high welding quality, smooth welding joints, and less prone to problems such as weld cracks.

Easy installation: Prefabricated welded stainless steel pipe with flange can be directly installed on the pipe without additional processing and adjustment, saving installation time and labor costs.

Good corrosion resistance: SS 316L pipe has strong corrosion resistance, can be used for a long time in a humid or corrosive environment, and is not easy to rust, corrode or wear.
