Compliance with Dn and cylindrical pipe thread G. Tees are available in the series ГОСТ 8943-8968; face length L — according to standard size. Thread BP (internal) / HP (external) — according to the design.
Ductile iron is a classic for threaded mounting (black/galvanized); steel and stainless steel are suitable for increased requirements.
Threaded is mounted on a thread without welding — it is convenient for small diameters and quick installation; steel (ГОСТ 17376) is butt-welded and designed for large diameters and pressures.
Cylindrical tube G according to DN: Ду15=G½", Ду25=G1", Ду50=G2" and so on.
Ductile iron (black/galvanized), steel, stainless steel.
Ductile iron threaded fittings — up to Ру16.
Yes — see "Transition tee" for smaller diameter branches.
