Pipe Reducing Tee

Comparing with SS304, SS316 Reducing Tee have good performance in strength and toughness, also the corrosion resistance is more excellent.

Reducing Tee is a traditional branch connection fitting that provides branches for the run pipe while changing the pipe diameter. The diverse functions make it more prevalent in pipe fittings.

Stainless Steel Reducing Tees are very practical in oil, gas, water pipes, power plant, construction and food industry.

What is SS316?

SS316 is a code that represents A182 F316, A403 WP316 and other derived species that SS316L and SS316H. But UNS designation S31600 only refers to A182 F316 Forged Fittings and A403 WP316 Butt Weld Fittings.

By the way, UNS designation of SS316L is 31603, SS316H is 31609, and SS316N is 31651.

SS UNS S31600 Forged Fittings and Butt Weld Fittings

Pipe Tee is one type of pipe fittings. In general, there are two types of SS316 Reducing Tee that Butt Weld Reducing Tee and Socket Weld Reducing Tee.

SS UNS S31600 butt weld fittings are usually used in pipe system with larger diameter, since its dimension range is larger. It has exactly same diameter with the pipeline which matched.

Due to socket welding requires the pipe insert into the socket, so the diameter of socket weld fittings is larger than the pipe itself.

Therefore, even though they are both weld connection pipe fittings, but their materials grade and Technics are different.

While people describe the material as ASTM A403 WP316, then we will know they are requiring butt weld fittings. If ASTM A182 F316, then it is forged steel fittings.
