ASME SA312 TP317L 1.4438 Stainless Steel Welded Pipe High Temperature
TP 317L is a chromium nickel molybdenum alloy that can perform under high temperatures. The alloy is solid solution heated for strength and the pipes are produced through different manufacturing mechanisms. The SA 312 TP 317L products have high yield strengths and can perform well under stress conditions. They have elongation rate higher than 35%
The 317L is also much corrosion resistance to the sulfur gas attacks at condensation. The lower carbon means that the product could be used with less intergranular corrosion while welding and it reduces the sensitization of the material. Also, high temperature applications with other mild chemicals are possible as well. The material is non-magnetic. The 317L could be used with high concentrations of hydrochloric, sulfuric and other acids under temperatures lower than 38 degrees Celsius

Applications
The 317L grade austenitic stainless steel is used in a variety of applications such as power plant, paper and pulp processing plants, textile equipment, petrochemical processing plants, food processing plants, flue gas desulfurization scrubbers and in chemical processing plants. This range of applications is possible because the material is malleable and durable. It is also a chromium, nickel and molybdenum alloy.


To ensure the tubes meet the required standards, they are subjected to several tests like the Product Analysis, Hardness, Mechanical, Flattening, Flaring,
Hydrostatic, or NDT tests, based on the client’s test requirements. The tubes must also conform to the applicable provisions of the current edition of Specification A 450/A 450M.
The ASTM A179 Tubes come in different sizes and varying wall thicknesses, and U-bending tubes can also be offered. Additionally, the tubes are subject to various test requirements, including ASTM A179 Tubes (ASME SA179 Tubes) Chemical Compositions, Mechanical Properties, Wall Thickness Tolerance, Outside Diameter Tolerance, Cut Length Tolerance, and Hydrostatic Test Pressures, to ensure quality.







Widely used in petroleum, chemical, medical, food, light industry, Industrial pipes and mechanical structural parts such as mechanical meters. In addition, when the bending and torsion strength are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts. And engineering structure.It is also often used as furniture and kitchen utensils.
