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.
Что такое ASTM A420 WPL6 low-temperature pipe cap?
Ан 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, толщина стенки, piping code and complete service conditions. These requirements must be confirmed before manufacture.

Производство, осмотр и документация
WPL6 production and release require careful control of raw material, термическая обработка, impact specimens, test temperature and traceability. The manufacturer must receive the complete minimum-design-temperature and acceptance requirements before confirming supply.
Test temperature, specimen orientation, size and absorbed-energy criteria reviewed against the order.
Treatment route and batch traceability linked to the material certificate.
Cap geometry, стена, bevel and specified NDE verified before release.
МТС, impact results, heat treatment and inspection records compiled as ordered.

Часто задаваемые вопросы
Что такое 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, термическая обработка, wall thickness and ordered impact test data. Confirm the project minimum design metal temperature and acceptance requirements.
Is WPL6 a cryogenic stainless steel?
Нет. 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?
Да, subject to a technical review of size, exact wall, формирование маршрута, heat treatment and impact specimen requirements.
