Pipe Cap

Introduction to Carbon Steel Elliptical Head

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

An elliptical head is a type of boiler component in pressure vessels, commonly 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 distinguish 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, disc-shaped, hemispherical, conical shell, and flat cover, etc. Among them, spherical, elliptical, disc-shaped, and hemispherical end caps are collectively referred to as convex end caps.

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

Application Fields

Headers are an indispensable and important 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 across various fields such as chemicals, construction, water supply, drainage, oil, light and heavy industries, refrigeration, sanitation, plumbing, firefighting, electricity, aerospace, and shipbuilding.

Procurement Recommendation

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

2: manufacturers of end caps need to provide material test reports and other relevant documents for end caps.

3: The head cap must have corresponding specification model stamping and marking.
