Detailed Introduction

American standard pipe caps are pipe end closure fittings used in conjunction with ASME B36.10M carbon steel pipes and ASME B36.19M stainless steel pipes. Their main functions are to close pipe ends, block medium flow, and reserve spare pipe openings. They can also serve as temporary seals during pipeline hydrostatic testing to reduce impurities entering the pipeline. Products use NPS inch specifications, covering NPS 1/2″ to NPS 48″, with wall thicknesses including Sch10, Sch40, Sch80, Sch160, SchXXS, and pressure ratings covering Class150 to Class1500. Materials are selected according to ASTM grades: carbon steel includes A234 WPB and A105, stainless steel includes A403 WP304 and WP316L, and alloy steel includes A234 WP11, WP22, and the A182 series. Structural forms include elliptical, dished, hemispherical, spherical, and flat bottom, and specific configurations can be confirmed according to project requirements.

Produced according to ASME B16.9, ASME B16.25, and ANSI B36.10M/B36.19M standards, with dimensions, bevels, and wall thicknesses aligned with the American standard system, facilitating acceptance in overseas American standard projects and replacement of imported fittings.
Specifications cover NPS 1/2″ to NPS 48″, wall thicknesses from Sch10 to SchXXS, and pressure ratings from Class150 to Class1500, allowing matching of corresponding models according to pipeline diameter and pressure rating.
Materials are selected according to ASTM grades: carbon steel A234 WPB and A105, stainless steel A403 WP304 and WP316L, and alloy steel A234 WP11, WP22, and the A182 series, adapting to different media and temperature conditions.
The mainstream processes are hot-pressed seamless forming, steel plate rolled and welded fabrication, and forged processing. Seamless pipe caps have no splice welds and uniform wall thickness, making them suitable for pipe end closure where sealing performance is required.
Export orders can be accompanied by MTC material certificates, UT non-destructive testing reports, and hydrostatic test reports, for acceptance in overseas EPC projects and customs clearance.
Supports customization for non-standard sizes, special materials, and process upgrades. Special diameters, thickened walls, special arc heights, non-standard bevels, and English markings can be confirmed according to project requirements.
