Detailed Introduction
Japanese standard branch outlet adopts JIS standard forged blanks, formed through forging, heat treatment, non-destructive testing, and CNC machining. During installation, there is no need to cut the main pipe; it is directly welded onto the outer wall of the main pipe to lead out the branch, relying on the forged body itself to complete the opening reinforcement, avoiding the stress concentration and erosion leakage hazards caused by on-site welding of reinforcement pads. Product specifications cover DN6-DN100, pressure ratings cover 3000LB, 6000LB, 9000LB, matching JIS steel pipe SCH wall thickness series; threads adopt PT/PS Japanese standard tapered pipe threads. Materials include S25C carbon steel, SF450 forged steel, SUS304, SUS316, heat-resistant alloy steel, and duplex steel. JIS supporting material certificates and UT/MT inspection reports can be provided, meeting Japanese equipment inspection requirements, accommodating both new Japanese-style engineering projects and old Japanese standard pipeline modifications, supporting spot supply and non-standard customization according to drawings.
