Fabricated Tee Type Strainer – ANSI Class 300LBS, Carbon & Stainless Steel, WN Flanged

Tengs Valve supplies fabricated Tee type strainers rated ANSI Class 300LBS (CL300) for medium and high pressure pipeline service. The Tee body uses a standard pipe tee with a bolted cover on the branch, so the screen can be removed for cleaning without cutting the main pipeline. Sizes range from 2" to 24" (DN50–DN600). Tee body materials include A234-WPB, A106, SS304, SS316, SS304L and SS316L. Flanges are WN type. Screen materials include 304SS and 316SS. End connections include BW, RF and RTJ. NACE MR0175 available for sour service. The RTJ groove dimensions listed below are specific to Class 300 flanges.

Why Choose a Class 300 Tee Type Strainer?

Class 300 tee type strainers are used in medium and high pressure pipeline systems where Class 150 would be insufficient. The RTJ (Ring Type Joint) groove option provides a metal-to-metal seal for high pressure and high temperature service, which is common in oil, gas and petrochemical applications. The Tee body design with WN flanges offers strong welded connections and easy screen access for maintenance.

Applications

• Medium and high pressure oil & gas pipelines
• Sour service pipelines (NACE MR0175)
• Petrochemical and chemical plants
• Power generation steam lines
• Water injection systems
• Protection of pumps, valves and meters
