ASTM A420 WPL6 Low Temperature Pipe Cap
A butt-welded pipeline closure for low-temperature carbon steel systems, supplied against the ordered impact test, heat treatment and traceability requirements.
Apa itu ASTM A420 WPL6 low-temperature pipe cap?
Sebuah ASTM A420 WPL6 pipe cap is a wrought low-temperature carbon steel fitting used to close the end of a butt-welded pipeline. It is selected when the design specification requires carbon steel fitting toughness at a stated low temperature rather than the general moderate-temperature service associated with ASTM A234 WPB.
WPL6 should not be treated as a generic cryogenic alloy. Allowable design temperature and suitability depend on the ordered heat treatment, impact test temperature and results, ketebalan dinding, piping code and complete service conditions. These requirements must be confirmed before manufacture.

A420 WPL6 vs A234 WPB pipe cap
| Titik seleksi | ASTM A420 WPL6 | ASTM A234 WPB |
|---|---|---|
| Service focus | Low-temperature carbon steel piping | Sedang- and elevated-temperature carbon steel piping |
| Impact toughness | Ordered low-temperature impact testing is central to material qualification | Project or code impact testing must be considered separately |
| Documentation focus | Heat treatment and impact test records | Kimia, mechanical properties and general inspection records |
| Seleksi yang khas | Refrigerated process, cold climate and low-temperature utilities | Minyak, gas, uap, power and general process service |
Aplikasi yang umum
| Industri | Layanan khas | Alasan pemilihan |
|---|---|---|
| Low-temperature process | Cold hydrocarbon and process utility closures | Specified impact toughness at the ordered temperature |
| Pendinginan | Industrial refrigeration auxiliaries and headers | Low-temperature carbon steel material route |
| Cold-climate facilities | Outdoor process and utility systems | Project-defined toughness and traceability |
| LPG/LNG support systems | Selected non-cryogenic auxiliaries within qualified temperature limits | Carbon steel solution where the design specification explicitly permits WPL6 |
Contoh penerapan hanya sebagai panduan saja. Insinyur proyek harus memastikan kompatibilitas material, tunjangan korosi, persyaratan dampak dan kepatuhan kode desain.
Manufaktur, inspeksi dan dokumentasi
WPL6 production and release require careful control of raw material, perlakuan panas, impact specimens, test temperature and traceability. The manufacturer must receive the complete minimum-design-temperature and acceptance requirements before confirming supply.
Suhu uji, specimen orientation, size and absorbed-energy criteria reviewed against the order.
Treatment route and batch traceability linked to the material certificate.
Cap geometry, dinding, bevel and specified NDE verified before release.
MTC, impact results, heat treatment and inspection records compiled as ordered.

Pertanyaan yang sering diajukan
Apa ASTM A420 WPL6 used for?
It is a low-temperature carbon steel fitting grade used where the piping specification requires verified toughness at a defined low temperature.
What is the minimum service temperature of WPL6?
A single universal service limit should not be assigned without the applicable piping code, perlakuan panas, wall thickness and ordered impact test data. Confirm the project minimum design metal temperature and acceptance requirements.
Is WPL6 a cryogenic stainless steel?
TIDAK. WPL6 is a low-temperature carbon steel fitting grade. True cryogenic services may require austenitic stainless steel or nickel alloy selected by the project engineer.
What documents prove low-temperature qualification?
The data package commonly includes the MTC, heat-treatment record and impact-test report showing specimen details, test temperature and results, plus traceability to the fitting heat or batch.
Can heavy-wall WPL6 caps be supplied?
Ya, subject to a technical review of size, exact wall, membentuk rute, heat treatment and impact specimen requirements.
