Welded pipe cap

A pipe cap is a fitting welded at the end of a steel pipe to seal the pipeline, and its function is similar to that of a pipe plug or stopper. The main materials include carbon steel, stainless steel, and alloy steel, with specifications ranging from DN15 to DN1200, and a wall thickness of SCH5-SCH160, in compliance with multiple international and domestic standards such as ASME, DIN, etc. Pipe caps come in various shapes, including convex (hemispherical, elliptical, disc-shaped, spherical), conical shell, flat cover, etc. They are widely used in fields such as petrochemicals, nuclear power, ships, medical equipment, etc.
Cangzhou, China is the main base for domestic pipeline equipment manufacturing, with more than 3200 production enterprises. Its products cover seamless steel pipes, flanges, valves, and various types of pipe fittings, with an annual processing capacity of 25 million tons and gradually upgrading to high-end manufacturing. The international standards for pipe flanges are divided into the European system (represented by German DIN) and the American system (represented by American ANSI), and the ISO 7005-1 standard integrates these two systems into a universal specification.
