Execution standard of head (stainless steel head)

Head is a metal part used to close the end of pipeline, vessel, tank and other equipments. Stainless steel head, on the other hand, is a head made of stainless steel material with good corrosion resistance and high strength. In order to ensure the quality and safety of stainless steel head, a series of execution standards must be followed.

Head (stainless steel head) implementation standards

I. Overview

Head is a metal part used to close the end of pipeline, vessel, tank and other equipments. Stainless steel head, on the other hand, is a head made of stainless steel material with good corrosion resistance and high strength. In order to ensure the quality and safety of stainless steel head, a series of execution standards must be followed.

II. Execution standards

1. Material standard: Stainless steel head shall be made of high quality stainless steel material, such as 304, 316 and other materials. The material should conform to relevant national standards, including chemical composition, mechanical properties, corrosion resistance and other requirements.
2. Manufacturing process standard: The manufacturing process of stainless steel head shall conform to relevant national standards, including requirements on molding, welding, heat treatment and so on. Strict quality control should be carried out in the manufacturing process to ensure the quality of head.
3. Dimension standard: The dimension of stainless steel head shall meet the design requirements, including the dimension tolerance of diameter, length, thickness and so on. If the size is too big, it will affect the installation and use of equipment, and if the size is too small, it may not be able to meet the use requirements.
4. Performance standard: Stainless steel head should have good performance of pressure resistance, corrosion resistance, high temperature resistance and so on. Performance standard is an important guarantee to ensure the safe use of end sockets, which must conform to the relevant national standards.
5. Inspection standard: Stainless steel head shall be strictly inspected in the manufacturing process, including material inspection, manufacturing process inspection, size inspection, performance inspection and other aspects of inspection. The inspection result shall conform to the relevant national standards to ensure the quality and safety performance of the head.

III. Specific standard content (take length as an example)

Length of end socket refers to the length of end socket in axial direction. The length shall conform to the design requirements and follow the relevant dimension tolerance standard. For example, the length of 600mm stainless steel head should have its dimension tolerance within ±1mm. The specific standard content also includes other parameters, such as diameter, thickness, surface quality and so on.

Four, summarize

As an important metal part, the quality and safety performance of stainless steel head is crucial. In order to ensure the quality and safety of stainless steel head
