ASTM A312/ASME SA312 TP316L SMLS Stainless Steel Pipe

About 316L material Pipe

What Is Stainless Steel 316l Pipe
Stainless steel 316l pipe is a low carbon austenitic alloy. The pipes in this grade are designed with a superior chemical composition of chromium, nickel coupled with molybdenum. The outstanding composition gives these modules enhanced corrosion and oxidation resistance. The pipes are resistant against carbide precipitation and can be welded in place easily following standard welding procedures.

What Is L In 316l Stainless Steel Pipe
The L in austenitic stainless steel 316l pipe grade signifies the content of lower carbon within the pipe.

Different Between Stainless Steel 316l Seamless And Welded Pipe
Grade 316l pipes are generally designed in welded and seamless configurations. Both these piping components can be distinguished based on certain features.

• Stainless steel 316l seamless pipes are designed by passing hot steel billets through a metal grade. A welded pipe configuration is produced by welding pieces of sheets or strips to precisely shape the module.
• Seamless pipes have superior strength and load-bearing capacity when compared to a standard welded grade pipe.
• Stainless steel 316l welded pipes are comparatively cheaper than a SS 316ti seamless pipe grade.

ASTM A312 Gr Tp316l Pipe Vs ASME Sa 312 Grade 316 Pipe
ASTM and ASME are important standards that play a pivotal role in manufacturing the pipes in the 316 grade. Both the grade are nearly identical but can be differentiated on certain aspects.

• ASME Sa 312 Grade 316 pipe comes under a standard that specifies design codes and standards for different pressure-rated applications. ASTM A321 Gr Tp316l pipe covers shapes, sizes, and structural qualities of different piping items.
• ASTM grade covers approximately 12,000 or more standards, while ASME covers nearly 600 technical standards.

Different Between Stainless Steel 316l seamless Pipe and SS 316l erw pipe

• Stainless steel 316l erw pipe is manufactured by welding metal longitudinally. SS 316l seamless pipe is manufactured by passing hot billets through extruded metal.
• Seamless pipes are expensive; however, they have a higher load-bearing capacity than erw pipes.

What Is 316l Stainless Steel Used For
Stainless steel 316l grade is commonly seen in the following industries.

• Chemical and food processing
• Petrochemical
• Potable water supply
• Pharmaceutical equipment
• Architectural systems
• Offshore and marine applications
