Carbon Steel A234 WPB, A860 WPHY42/WPHY46/WPHY52/WPHY56 BW Cap Large Diameter Steel Pipe Cap

A234 WPB is a standard specification for piping fittings of wrought carbon steel and alloy steel for moderate and high-temperature service. A234 WPB carbon steel pipe end caps are used to close the ends of pipes, providing a seal to prevent leakage and contamination. These end caps are designed to fit large-diameter pipes and are commonly used in various industrial applications, including oil and gas, chemical processing, and power generation.

The “WPB” in A234 WPB stands for “wrought pipe fitting, butt-weld,” indicating that these fittings are designed to be welded to the pipe for a strong and leak-resistant connection. They are manufactured in accordance with the ASTM A234 specification, which covers seamless and welded carbon steel and alloy steel pipe fittings.

When selecting A234 WPB carbon steel pipe end caps for large diameters, it’s important to consider the specific requirements of the application, such as pressure rating, temperature range, and material compatibility. Additionally, proper installation and welding procedures should be followed to ensure the integrity of the piping system.

Package

We marked all ASTM A234 Pipe Fittings with Grade, Lot No, Size, Standard and Schedule Thickness. Our workers packed large diameter steel pipe caps into wooden pallets or cases.

Clear labels are tagged on the outside of the package for easy identification of the quantity and product I.D. great care is taken during operation and transportation.

Inspection

Visual the surface of cap fittings body. Such as dents, die marks, porosity, undercuts etc.
Check the marking. Such as size, material code and grade, thickness, heat no.
Measure the size of large steel pipe cap. Such as the diameter, thickness, height of end to end.
