Steel Pipe Caps

Our high-quality pipe caps are essential components designed to seal the ends of pipelines, protecting the pipe threads and internal surfaces from debris, corrosion, and damage during transit or storage. Manufactured to withstand high pressure and extreme temperatures, these caps ensure a leak-proof termination for various piping systems.

1. Technical Specifications

Type:Butt Weld (BW) Caps, Socket Weld (SW) Caps, Threaded (NPT/BSPT) Caps.

Size Range:1/2" to 72" (DN15 – DN1800).

Wall Thickness:SCH 5S to SCH XXS.

Shapes:Elliptical, Hemispherical, Flat, and Round caps.

2. Material Grades & Standards

We provide pipe caps in a full range of materials to match your existing piping infrastructure:

Carbon Steel:ASTM A234 WPB, WPC; ST37.2, A105.

Stainless Steel:ASTM A403 WP304/304L, WP316/316L, 321, 310S.

Alloy Steel:ASTM A234 WP1, WP5, WP9, WP11, WP22, WP91.

Low Temperature:ASTM A420 WPL6.

High Yield:MSS-SP-75 WPHY 42, 52, 60, 65, 70.
