Protection and analysis of steel pipe caps

Protection and analysis of steel pipe caps

Carbon steel pipe caps include the design of convex pipe caps, conical shells, reduced diameter sections, flat caps and reduced diameter heads for tightening mouth.

Convex tube caps include: hemispherical tube caps, oval tube caps, dish-shaped tube caps and ball-shaped tube caps. From the point of view of force, the convex tube cap from the hemispherical tube cap is gradually not good, but from the point of view of manufacturing difficulty, it is gradually easy to manufacture.

Carbon steel pipe cap, also known as plug, cap, pipe cover, head, used to close the pipeline, the role is the same as pipe plug, but the pipe cap can be directly screw on the pipe, do not need other pipe fittings. The design of the pipe cap includes a convex pipe cap, a cone shell, a reducer section, a flat cap and a tightening mouth.

The material of carbon steel head is mainly Q235, 20#, A3, 16 manganese, Q345B, 45 steel and so on. The standard is GB/T25198-2010(pressure vessel head standard), and pipeline standard GB/T12459-2005, GB/T13401-2005 and so on.

Pipe cap is an indispensable part of pressure vessel equipment in petrochemical industry, nuclear energy, water conservancy, food, machinery, chemical fertilizer, shipbuilding and many other industries. The pipe cap is the end cap of the pressure vessel, which is a main pressure bearing part of the pressure vessel. The function is to seal. The pipe cap is the upper and lower bottom of the pressure vessel of the tank or the end of the pipe. It is not ready to extend further, so it is sealed in the welded form of the pip
