The GOST 17376 Carbon Steel Tee is a key seamless fitting designed for Russian and CIS industrial piping systems. Manufactured by hot forming or hydraulic bulging, these tees provide a 90° branch for oil, gas, and steam lines. The standard covers both Equal (Ravnoprokho-dnoy) and Reducing (Perekhodnoy) types. Using high-quality steels like 20 or 09G2S, these fittings ensure structural integrity under high pressure and are strictly dimensioned to match GOST-standard seamless pipes.
