ASTM A234 WPB Pipe Fittings Carbon Steel Caps According To ASME B16.9

Carbon Steel Caps, It is a key component used for sealing pipelines in pressure vessels and piping systems, and can be directly screwed onto the pipe body. The product materials include Q235, 20 #, 16Mn WPB and other carbon steel types, and comply with the GB/T25198-2010,ASTM A234,ASME B16.9 pressure vessel head standard and GB/T12459-2005 pipeline standard. Mainly used in the fields of petrochemicals, pharmaceutical equipment, food processing, nuclear power energy, etc
According to structure, it can be divided into four types: convex pipe cap, conical shell, variable diameter section, flat cap, and tight mouth. Among them, convex pipe cap includes four forms: hemispherical, elliptical, disc-shaped, and spherical cap. The specifications cover diameters of DN15-DN1200 and wall thicknesses of 1-100mm. The manufacturing process includes hot forging, cold stamping, spinning, etc. The direction of the joint weld is limited to radial and circumferential directions, and refrigeration equipment can be exempted from some joint standards. After undergoing quality inspection processes such as raw material inspection, forming accuracy testing, and weld seam testing.

Convex pipe caps include hemispherical pipe caps, elliptical pipe caps, disc-shaped pipe caps, and spherical cap shaped pipe caps. From the perspective of force, the hemispherical cap in the convex cap is gradually becoming less desirable, but from the perspective of manufacturing difficulty, it is gradually becoming easier to manufacture.
Usage: Water, beverages, beer, food, petrochemicals, nuclear power, machinery, medical equipment, fertilizers, shipbuilding, waterproofing treatment, pipelines, etc

Packaging: wooden crate, cardboard box

Avoid splicing at the r position of the disc-shaped pipe cap, as it may cause thinning and high stress.
