Threaded fittings belong to the group of high-pressure fittings. They are available in all imperial sizes. Each fitting is permanently marked with its size, material grade, heat number, and pressure class. They ensure the safety, reliability, and long service life of your piping system. All threaded fittings are supplied with a 3.1 material certificate.
Stainless Steel Grade 316L is one of the most widely used stainless steels due to its excellent corrosion resistance. It also offers outstanding weldability.
Also known as: DIN 1.4401, DIN 1.4404, SS316, SS316L, AISI 316, AISI 316L
Typical applications: heat exchangers, pharmaceutical equipment, dairy industry, brewing industry, marine fittings, coastal infrastructure, and food processing systems.
Advantages of 316L stainless steel:
- Non-magnetic
- Excellent ductility
- Outstanding impact resistance
- Excellent weldability
- High mechanical strength
- Wide operating temperature range
Other sizes are also available on request. If you have any questions, please contact us. Send your inquiry to biuro@polberis.pl, and we will prepare a competitive quotation tailored to your requirements.
