Carbon steel elliptical head

Introduction to Carbon Steel Elliptical Heads

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

An elliptical head is a type of boiler component in pressure vessels, typically used at the ends of pressure vessels.

A type of welding fitting used for sealing the end of a pipeline.

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

Variety Classification

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 caps are collectively referred to as convex caps.

By welding classification: It can be divided into large-diameter butt-welded caps and socket-welded caps.

Application Fields

The head is an indispensable and essential component in pressure vessels across various industries, including petrochemical, nuclear, and food processing.

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

Procurement Recommendations

1: Recommend purchasing from a reputable cap manufacturer with a certain production scale.

2: manufacturers of headed caps must provide material inspection reports and related documents.

3: The cap must have corresponding specification model embossed and marked.
