Type classification of head and tube cap

Type classification of head and tube cap  A head is a part of a container that is welded to the cylinder.  According to the different geometric shape, it can be divided into spherical, oval, disc, spherical crown, cone shell and cap, among which spherical, oval, disc, spherical crown head is collectively referred to as convex head.  In the welding is divided into butt welding head, socket welding head.  Used for all kinds of container equipment, such as storage tank, heat exchanger, tower, reactor, boiler and separation equipment, etc.  The materials are carbon steel (A3, 20#, Q235, Q345B, 16Mn, etc.), stainless steel (304, 321, 304L, 316, 316L, etc.), alloy steel (15Mo3 15CrMoV 35CrMoV 45CrMo), aluminum, titanium, copper, nickel and nickel alloy, etc.

Casing) cap, also known as head, plug, cover, pipe cover, head, fitting welded to the end of the pipe or fitted to the external thread of the end to cover the casing.  Used to seal the pipeline, the function is the same as pipe blocking.

 The head refers to the element used to close the end of the container so that the internal and external media are isolated, also known as the end cover.  The head of a cylindrical vessel is usually a rotary case.  According to the shape of the head surface, it can be divided into convex shape, conical shape, flat shape and combination shape.  Convex heads refer to heads with convex outer surface shape, such as hemispherical, oval, disc and unflanged spherical heads.  Some gas cylinders adopt convex inward combined bottom head, which can not only ensure the strength, but also meet the needs of smooth operation.

 Type: the blind is similar in form, except that the blind is removable and blocked, while the welded pipe cap is not removable.  The pipe cap includes convex pipe cap, cone shell, reducer section, flat cover and the design of tightening mouth.  Convex pipe cap includes: hemispherical pipe cap, oval pipe cap, disc pipe cap and dome pipe cap.  From the point of view of force, convex pipe cap is gradually bad from the hemispherical pipe cap, but from the point of view of manufacturing difficulty, gradually good manufacturing.

 The type of head and pipe cap classification is mainly in accordance with customer requirements production processing molding, welcome users who need pipe products to inquire and order!
