Introduction
Core changes in the standard revision
| Comparison dimensions | CJ/T 117-2000 | CJ/T 117-2018 |
|---|---|---|
| Standard name | Copper pipe fittings for construction (socket and spigot type) | Socket and spigot metal pipe fittings for construction |
| Scope of application | DN≤100mm | DN≤300mm (newly added stainless steel fittings) |
| Material requirements | Copper alloy only | S6 new stainless steel grades including S30403/S31603 |
| Test items | Burst pressure test | Six new connection performance tests |
Analysis of key technical requirements
Material selection specifications
The standard specifies requirements for two types of materials:
- Stainless steel pipe fittings: Preferentially use austenitic stainless steel such as 06Cr19Ni10(S30408) and 022Cr17Ni12Mo2(S31603)
- Copper pipe fittings: Should comply with GB/T 18033 TP2/TU2 copper tubes must be supplied in semi-hard state (Y2) or hard state (Y)
Connection performance test system
| Test items | Test conditions | Qualification standards |
|---|---|---|
| Pressure test | 2.5MPa/1min | No leakage and no plastic deformation |
| Pull-out test | DN100 pipe fittings ≥60kN | No falling off at the connection |
| Hot and cold cycle | 20℃⇄93℃/5000 times | Sealing structure integrity |
Project implementation suggestions
- Preferably use socket-type argon arc welding stainless steel pipe fittings for high temperature and high pressure systems
- When connecting copper pipe fittings, the brazing temperature should be controlled within the range of 645-790℃
- DN≥200mm pipe fittings should be subjected to on-site vibration test
