S31803 12Cr2Mo1 Alloy Steel Pipe End Cap SCH5S SCH160 Rustproof
Alloy steel seamless steel pipe 12Cr2Mo1 16 "alloy head end ca
specific characteristics
During splicing, only radial and circumferential weld directions are allowed. This requirement may be cancelled in the future for large pipe caps. The splicing distance shall be more than 3 δ, It shall not be less than 100mm (the welding heat affected zone is a high stress zone, and the chemical composition in this zone will be burned. Therefore, it is necessary to avoid the high stress zone, which is related to the thickness. According to practical experience, the stress attenuation length is greater than 3 δ, And not less than 100mm). However, refrigeration equipment is difficult to meet this requirement, which has its particularity.
Use of head
Head is an indispensable part of pressure vessel equipment in petrochemical, atomic energy and food pharmaceutical industries.
1. The head is the end cover on the pressure vessel and a main pressure bearing part of the pressure vessel.
2. The quality of the head is directly related to the long-term safe and reliable operation of the pressure vessel.
