Stainless steel butt weld tee is a common pipeline connection accessory consisting of three ports. It is mainly used to connect pipelines, control fluid flow, and achieve operations. Its advantages lie in its simple structure, low flow resistance, fast response, flexible switching, and long service life. By connecting butt weld tee, complex pipeline systems can be assembled and debugged, improving the convenience.

Butt weld tee is widely used in fluid control and transportation systems. At the same time, it can also be used in fields such as water supply, drainage, and heating.

Standards for stainless steel butt weld tee cover multiple aspects. These standards collectively ensure that the quality and performance of butt weld tee. The common American standard production standard is ASME B16.9; The material standard is ASTM A403.

Types of Stainless Steel Butt Weld Tee

According to ends diameter, stainless steel butt weld tees can be divided into equal tees and reducing tees. Equal tee is three ends with the same diameter, while differential diameter tee is the ends with different diameters.

Material Standard

Stainless steel butt weld tee has excellent corrosion resistance, high strength, and good processing performance. ASTM A403 standard is a specification developed by the (ASTM) for the design, manufacturing, austenitic and ferritic stainless steel fittings. Common stainless steel materials include ASTM A403 WP304 and WP316.
