SS317L Steel Pipe With Tee

SS317L is the austenitic stainless steel and a low-carbon version of 317 stainless steel. The "L" stands for "Low Carbon," and its carbon content is typically less than 0.03%. HT PIPE is a 317l stainless steel Pipe with tee supplier with 15+ export experience.

About SS317L Tee

Straight Tee: A straight tee with three equal-sized connections is used to distribute flow from a main pipe to branches, either evenly or unevenly.

Reducing Tee: A branch pipe connection is smaller than the main pipe connection and is used to connect pipes of different diameters.

 

AISI 317L Stainless Steel Pipe And Tee Fittings Standard

ASTM A312 Standard: Specification for Seamless, Welded, and Heavily Cold Worked Austenitic Stainless Steel Pipes

 

ASTM A403: ASTM A403 / A403M Standard Specification for Wrought Austenitic Stainless Steel Piping Fitting

 

ASME B16.9: Specification for factory-made wrought steel but-welding fittings

 

SS317 material Corrosion Resistance

• Resistance to Pitting and Crevice Corrosion: SS317L Steel Pipe With Tee provides a strong defense against localized corrosion in processes handling seawater, saltwater, and halogenated materials.
• Resistance to Stress Corrosion Cracking (SCC): Many materials can experience brittle cracking in tensile environments containing chloride ions. 317L's higher nickel and molybdenum content provides enhanced SCC resistance.
• Resistance to a variety of acids and chemicals: SS317L Steel Pipe With Tee exhibits excellent resistance to sulfuric, phosphoric, and acetic acids, as well as various organic acids and alkaline solutions. 

 

UNS S31703 pipe Type

Seamless Pipe: Manufactured through piercing and cold drawing/hot rolling, it features no welds, excellent uniformity, and high pressure-bearing capacity, making it the preferred choice for high-pressure systems.

Welded Pipe: Manufactured by coiling steel plates or strips and welding them using automated welding techniques (such as TIG welding). It offers low cost, flexible dimensions, and is widely used in medium and low-pressure applications.

 

SS317L Steel Pipe With Tee Manufacturing

Hydraulic Bulging: A billet is placed in a mold, where high-pressure liquid is used to expand the billet into the shape of a tee. This is the current mainstream, efficient, and high-quality manufacturing method.

Hot Pressing: For large-diameter or thick-walled tees, a heating and subsequent pressing process is used.

 

317L Stainless Steel Pipe With Tee Applications

Chemical and Petrochemical Industries: In reactors, columns, and pipelines that come into contact with highly corrosive catalysts, intermediates, and products.

Oil and Gas Extraction: Used in downhole tubing, transmission pipelines, and processing facilities in high-sulfur and high-chloride formations.

Pharmaceutical and Biotechnology: Used in process piping systems (such as WFI water and pure steam) requiring high cleanliness and corrosion resistance, but these applications require attention to surface finish (such as electropolishing) and verification requirements.

Pulp and Paper Industry: Resisting corrosion from chlorides and chemical solutions in demanding chemical pulping and bleaching processes.

Marine and Desalination: Used in seawater cooling systems and core components of desalination plants, resisting the highly corrosive nature of seawater.

Flue Gas Desulfurization (FGD) Systems: Resisting corrosion from acidic condensate in absorption towers and flues.
