Steel Butt-Welding Pipe Fittings for Pressure Service and High Pressure Service (Schedule)
Elbows 90 deg. Steel Butt-welding
Elbows 90 deg. Steel Butt-welding is a group of 56 IMPA-coded items (codes 731451–731528) under Steel Butt-Welding Pipe Fittings for Pressure Service and High Pressure Service (Schedule) in the Pipe & Tube Fittings section (IMPA 73). All of them are priced per piece. Every item in the list is steel.
Buying guide
Butt-welding elbows turn a welded pipe run through 90 degrees. This group holds long-radius steel elbows in Schedule 40 and Schedule 80 for pressure-service pipework, in sizes from 15A, the schedule fittings that match pressure-service and high-pressure-service steel pipe.[1]
They go into fuel, lube-oil, steam, compressed-air and hydraulic systems. The engineer or a repair yard raises them with pipe renewals and new runs.
How to specify it
State the nominal size (A or inch), schedule (40 or 80, matched to the pipe wall), radius (long or short), angle and material. JIS B 2312 fittings are made to be butt-welded to pressure-service pipe (JIS G 3454), high-pressure pipe (JIS G 3455), high-temperature, alloy, stainless and low-temperature pipe, so name the pipe they join.[1]
Do not mix these with the FSGP fittings for ordinary pipe: JIS B 2311 covers fittings butt-welded to ordinary piping (JIS G 3452 SGP) of comparatively low working pressure, and their walls follow the thinner pipe.[2]
Rules and certificates
JIS B 2312:2024 (steel butt-welding pipe fittings) is a modified adoption of ISO 3419 and ISO 5251 and covers fittings for pressure, high-pressure, high-temperature, alloy, stainless, low-temperature and fired-heater piping.[1]
Questions buyers ask
- Long radius or short radius?
- Match the drawing or the elbow being cut out; the two are different centre-to-face lengths and are listed as separate groups in the catalogue.
- Sch 40 elbow on Sch 80 pipe?
- No; order the same schedule as the pipe so the bores and walls line up at the weld.
