We are the professional exporter and supplier of ASTM A312 TP316 Seamless Stainless Steel Pipes, ASME SA312 TP316L Seamless Stainless Steel Pipes
ASTM A 312 TP316 316L Pipe
Manufactured in compliance with ASTM A312 standards, Our ASTM A312 TP316L stainless steel pipes meet stringent quality requirements, ensuring consistency and reliability in performance. You can trust our TP316L pipes to deliver the durability and performance your projects demand.
ASTM A312 TP316 and TP316L
are designated with UNS S31600 and UNS S31603, respectively. Although more expensive, pipes made of TP316/ TP316L have higher level corrosion resistance than that ofTP304/ TP304L. They can be used for a diversified range of corrosive chemical process piping which involves inks, rayon, photographic chemicals, paper, textiles, bleaches, and rubber.
A312 TP316L is the low carbon version of A312 TP316 stainless. With the addition of molybdenum, the steel is popular for use in severe corrosion environments due to the materials immunity from boundary carbide precipitation (sensitisation). A312 TP316L material is widely used in heavy gauge welded components and weld annealing is only required where the material is for use in high stress environments. TP316L has an extensive variety of uses especially in marine applications due to the materials high corrosion resistance. Benefits of using Type 316L Stainless Steel Low carbon content eliminates carbon precipitation in the welding process Can be used in severe corrosive environments Improved anti-corrosion scope due to added Molybdenum Weld annealing only required in high stress applications Very similar to Grade 316 in chemical composition and mechanical properties.
We can also supply A312 TP316/316L Dual Grade Pipes from ABS,BV,DNV-GL class approved makers,Mill test certificate EN 10204 3.1 /3.2 certificate will be provided

ASTM A312 TP316L Heat Treatment
All pipes shall be furnished in the heat-treated condition in accordance with the required heat-treating temperature and cooling requirements, pipes shall be individually quenched in water or rapidly cooled by other means (direct quenched).
The pipe shall be free of scale and contaminating exogenous iron particles. Pickling, blasting, or surface finishing is not mandatory when the pipe is bright annealed.

ASTM A312 TP316L Pipes Permitted Variations in Wall Thickness
In addition to the implicit limitation of wall thickness for seamless pipe imposed by the limitation on weight in Specification A999/A999M, the wall thickness for seamless and welded pipe at any point shall be within the tolerances specified in Table 3, except that for welded pipe the weld area shall not be limited by the “Over” tolerance. The wall thickness and outside diameter for inspection for compliance with this requirement for pipe ordered by NPS and schedule number is shown in Table X1.1.

ASTM A312 Pipe Applications
ASTM A312 stainless steel pipe has an extremely wide range of applications.
In the chemical industry, due to the excellent corrosion resistance of stainless steel, can effectively prevent the corrosion and contamination of chemical substances on the pipeline, so it is widely used in the manufacture, storage, and delivery of chemical substances piping systems.
In the oil and gas industry, stainless steel pipelines can withstand the harsh conditions of high pressure and high temperature, as well as good anti-wear properties, become an important tool for drilling, extraction, and transport of oil and gas resources. In addition,
in the food and pharmaceutical industries, stainless steel piping has become a key part of the production process because it is non-toxic, odorless, non-polluting, and easy to clean and disinfect.
