Zhejiang Daye Flange Co., Ltd. is one of the leading manufacturers and suppliers of 304l 316l equal tee in China. With abundant experience, we are committed to providing high quality flanges made in China with competitive price. We warmly welcome you to buy durable 304l 316l equal tee in stock here from our factory. Also, quotation is available.
304L 316L equal tees are the basic category of stainless‑steel butt‑weld tee fittings. Their key feature is that all three ports share identical nominal diameter. They serve as core components for uniform fluid diversion and combining within piping systems. Both 304L and 316L are low‑carbon austenitic stainless‑steel grades. The suffix "L" stands for Low Carbon, providing better resistance to intergranular corrosion after welding compared with standard 304 / 316. They are the most widely‑adopted tee fittings for industrial and clean piping applications.
304L 316L equal tees mainly realize uniform fluid diversion / combining and branch pipe connections. They facilitate the construction of piping networks and are well‑suited for special‑medium service conditions. Featuring good corrosion resistance, they are applicable for piping carrying mildly corrosive media. Super stainless steel or duplex steel grades shall be selected for strongly corrosive‑media service.

FAQ
Q: What is the pressure‑bearing capacity of stainless‑steel equal tees?
A: The pressure‑bearing capacity is jointly determined by wall‑thickness schedule, material grade and operating temperature. At ambient temperature, Sch40 covers most medium‑low‑pressure service, while Sch80 is suitable for medium‑to‑high‑pressure applications. The allowable stress of materials decreases as temperature rises, so corresponding verification shall be performed.
Q: What is the standard surface treatment for industrial‑grade stainless‑steel tees?
A: Industrial‑grade tees normally receive pickling and passivation treatment to form a dense passive oxide film, improving rust and corrosion resistance. Sanitary‑grade tees require internal & external mirror polishing or electrolytic polishing to meet cleanliness specifications.
Q: Can equal tees be supplied in NACE sulphide‑resistant version?
A: Yes. Grades such as 316L can be manufactured from raw materials complying with NACE MR0175 / ISO 15156 for mild oil‑and‑gas service containing hydrogen sulphide. Duplex‑steel material is recommended for severe sulphide‑laden service conditions.
Q: Is heat treatment required after welding 304L 316L equal tees?
A: As a low‑carbon austenitic stainless steel, 304L 316Lmaintains good resistance to intergranular corrosion without post‑weld heat treatment under conventional welding conditions. Solution annealing may be applied for heavy‑wall sizes or special severe service per design requirements.
