ASTM A358 covers Electric Fusion Welded (EFW) Austenitic Stainless Steel Pipe for corrosive or high-temperature applications. The standard defines different pipe classes based on welding procedures, filler metal requirements, and inspection methods.
For ASTM A358 TP316L Stainless Steel Pipe, selecting the correct class depends on the pressure rating, service environment, welding quality requirements, and application standards.

Common welding methods for ASTM A358 TP316L Stainless Steel Pipe include:

• EFW (Electric Fusion Welding)
• GTAW (Gas Tungsten Arc Welding / TIG)
• SAW (Submerged Arc Welding)

Typical filler metals:

ER316L filler metal provides:

• Excellent corrosion resistance
• Good weld strength
• Reduced risk of intergranular corrosion

The absolute roughness of 316L stainless steel pipe is an important parameter used in fluid flow calculations, including pressure drop analysis, Reynolds number calculations, friction factor estimation, and pipeline design.
For a clean commercial 316L stainless steel pipe, the typical absolute roughness values are:

316L stainless steel has one of the lowest roughness values among industrial piping materials, which helps reduce:

• Pressure loss
• Turbulence
• Energy consumption
• Product contamination risk

• Chemical Processing Industry – Used for TP316L stainless steel pipe for chemical processing, including corrosive fluid pipelines, acid handling systems, and process equipment.
• Petrochemical & Oil Industry – Suitable for ASTM A358 TP316L EFW pipe for petrochemical applications, refinery piping, and high-temperature process systems.
• Marine & Offshore Engineering – Ideal for TP316L stainless steel pipe for marine applications, seawater pipelines, offshore platforms, and saltwater environments.
• Pharmaceutical & Food Processing – Applied in high purity stainless steel pipe systems, sanitary piping, and clean production equipment.
• Water Treatment & Desalination – Used as corrosion resistant stainless steel pipe for water treatment, RO systems, and desalination plants.
• Heat Exchanger & Power Generation – Suitable for ASTM A358 stainless steel pipe for heat exchanger applications and industrial cooling systems.

ASTM A358 EFW TP316L Stainless Steel Pipe is an Electric Fusion Welded (EFW) stainless steel pipe manufactured according to ASTM A358 using TP316L stainless steel. It is designed for applications requiring excellent corrosion resistance, high strength, and reliable welded performance.

TP316L has a lower carbon content (≤0.030%) than TP316, providing better resistance to intergranular corrosion after welding. It is widely used for chemical processing, marine, and pharmaceutical piping systems.

The pipe is manufactured according to ASTM A358 with dimensions based on ASME B36.19M Stainless Steel Pipe Standard. It is commonly supplied in Schedule 10S, Schedule 40S, and other wall thicknesses.

Schedule 10S stainless steel pipe refers to a pipe wall thickness specification designed for stainless steel piping systems. It provides a lightweight solution while maintaining good corrosion resistance and flow performance.
