Executive standard for pressing process of stainless steel cap

  Stainless steel cap is the main stress component of vessel cap. The quality of cap is related to the normal operation of vessel equipment. How to press stainless steel cap and the pressing method of stainless steel cap.

  The advantages of this method are convenient transportation, if it is too large, it will bring trouble in transportation; Large and medium-sized caps: splicing before forming, and the requirements in the standard are mainly for them (also the most common way); Small cap: general color one-time overall molding manufacturing method, advantages: outstanding overall effect. The existing cap standards in our country are formulated according to the different structural types (oval, dished, conical) and forming methods (stamping, spinning). This not only causes the unreasonable phenomenon that the quality requirements of different standard caps are not completely consistent, but also brings some difficulties to the selection and revision of standard caps.

  In the past, the cap standards were only matched with GB 150 "steel pressure vessel", that is, only considering the manufacturing, inspection and acceptance requirements of heads designed according to rules. However, China completed the double track system of the basic standard of pressure vessel (with "steel pressure vessel analysis and design standard") in GB 150 and JB 4732 as early as 1995, It can not be said that it is a major defect in the standardization of pressure vessels in China.
