Alloy steel pipe cap

Introduction to Carbon Steel Elliptical Head

Carbon steel elliptical end cap, also known as: blind plug, pipe plug.

The elliptical head is a type of boiler component in pressure vessels, commonly used at both ends of the pressure vessel.

Another product is a type of welded pipe fitting used for sealing at the end of pipelines.

Many customers believe that caps and pipe covers are the same, but that's not true. A simple way to differentiate between caps and pipe covers is that the straight edge height of pipe covers is higher than that of caps.

Variety Categories

By shape classification: They can be divided into spherical, elliptical, dish-shaped, hemispherical, conical shell, and flat cover, among others. Among them, spherical, elliptical, dish-shaped, and hemispherical end caps are collectively referred to as convex end caps.

By welding classification: available in large diameter butt-welding caps and socket-welding caps.

Application Fields

Head covers are an indispensable and essential component in pressure vessels across various industries, from petrochemicals and nuclear energy to food processing.

Due to the excellent comprehensive properties of carbon steel elliptical heads, they are widely used in basic engineering fields such as chemical industry, construction, water supply, drainage, oil industry, light and heavy industries, refrigeration, sanitation, plumbing, fire protection, electricity, aerospace, shipbuilding, and more.

Procurement Recommendations

1: Suggest purchasing from a reputable head cap manufacturer, which should have a certain production scale.

2: manufacturers of flanged heads must provide material test reports and related documents for the flanged heads.

3: The end caps must have corresponding specifications, model stamps, and markings.
