Detailed Introduction
American standard tees belong to the butt-welded pressure-bearing pipe fittings under the ASME system, and are mainly used at positions for main pipeline diversion, branch merging, and reducing connections. The products are formed in accordance with ASME B16.9, high-pressure fittings can be implemented under MSS SP-75, and the supporting pipeline size systems are ASME B36.10M and ASME B36.19M, and they can be used together with American standard elbows, flanges, and reducers. Structurally, they are divided into seamless stamped tees and steel plate rolled and welded tees. Small and medium diameters of NPS24 and below adopt integral hot stamping forming, while large diameters adopt steel plate pressing and welding forming. Commonly used materials include A106B, A234 WPB carbon steel, A403 WP304, WP316L stainless steel, and A234 WP11/WP22 alloy steel. Specifications use NPS inch diameters, wall thicknesses cover Sch40, Sch80, Sch160, XXS, and pressure pound ratings can be adapted from 150LB to 1500LB. UT/MT non-destructive testing, hydrostatic testing, material spectral inspection, and EN10204 3.1/3.2 certificates can be provided according to project requirements.

FAQ
Can American-standard tees be mixed with national-standard or European-standard pipe fittings?
American standards adopt the NPS inch sizing, Sch wall thickness, and LB pound rating systems; dimensional tolerances, pressure-bearing standards, and acceptance rules differ from national standards and European standards. For formal American-related engineering projects, it is not recommended to mix pipe fittings of other standards; for specific adaptation issues, please contact us to confirm.
Is it suitable for high-pressure oil and gas working conditions?
Optional Sch80, Sch160, and XXS thickened high-pressure models are available; pressure pound ratings can adapt to 150LB to 1500LB, used for high-pressure working conditions such as oil and gas and power stations. For specific model selection, please contact us to confirm.
