Stitching head detection test head prosperity head plant perennial wholesale and retail affordable diagram

Cangzhou prosperity head factory specializing in the production of large diameter head, good quality and reputation. Head plant introduction head set straight section of reason, which is connected with the cylinder girth welding has become two different geometries of the housing between here not only produce welding residual stress and a variety of welding defects, also produced edge stress, the deterioration of the premises by force status, stress concentration area; if the head with a straight section, which is connected with the cylinder into a butt weld curvature of the same cylinder and cylinder between the wall thickness are equal, where no edge stress, when the wall thickness is not equal to equal thickness can be localized thinning. Hebei prosperity head plant perennial mass production of various thickness head, shelf. Head is a boiler, pressure vessel main pressure parts and shape its structure design is reasonable, affecting boiler, pressure vessel safety work. Head There are many types, such as elliptical head, butterfly head, cone-shaped top, which several heads in the end what is the difference? Speaking from which their performance. Dished head dished head that is there hem spherical head. It there is a large bending stress, and ellipsoidal head mainly film stress, which is not ideal in engineering use. When using dished head, head transition zone corner radius should be not less than 10% of the inner diameter of the head, and not less than three times the thickness of the head, the inner radius of the sealing surface portion of the header should be less than the inner diameter of the head of . Prosperity head plant Gezhongfeibiao head, timely delivery, good reputation.
