Yanshan County Bo Yan Pipe Co., Ltd. is located in Yanshan County Industrial Development Zone. North of Beijing and Tianjin and Beijing-Shanghai railway to the east Bohai Sea, Tianjin Port, State Road across the county superior geographical conditions, carbon steel pipe cap GB, abundant local resources, carbon steel pipe cap manufacturer, for my company's development has laid a good foundation . Best-selling products, and exported to South Korea, steel pipe cap specifications, Vietnam, Singapore, Malaysia and other countries. I used to pursue "science and technology first, gaining the upper hand, quality, customer supreme, credit first" business ideas, is willing to domestic and foreign users and sincere welcome customers to work together to create a better future head of a large butterfly design standards ( 1) the different structure type, head different manufacturing methods while incorporating this standard, and put forward a unified manufacturing, testing and inspection requirements, which improve the quality of various head is necessary. (2) The standard both inclusive design by the rules (and JB150 supporting) the head, also inclusive design by analysis (and JB4732 supporting) the head, carbon steel pipe cap, for the first time in our steel pressure vessels Head of uniform quality requirements. (3) The text of this standard (mainly manufacturing head, inspection and acceptance requirements) as a mandatory provision, and the appendix of this standard (mainly various types of head size, the inner surface area, volume, mass, etc.) As a guide content, which is conducive to influence product quality and safety of the various elements of the uniform requirements, but also to the user of this standard to all kinds of factors do not affect the safety of selective space, making them according to actual needs, both in accordance with the selection criteria, in accordance with the appropriate design criteria, design their own calculations. Standard elliptical head outer layer thickness requirements in the design of elliptical head, we will strictly control the effective thickness, which the designer has enough technical test, but also the key to good and bad head. So under normal circumstances we require its thickness is how much? Let us wait and see. In recent years, thanks to the spinning manufacturing process for the manufacture of large-diameter oval head to bring the convenience. Elliptical head due to better overall performance, is widely used in low-pressure containers. Elliptical head by a half ellipsoidal and cylindrical straight edge segments. The role of the straight section is to avoid the connection weld head and the cylinder of the radius of curvature of the mutated appears to improve the situation by force welds. Due to changes in the curvature of the ellipsoid part warp Head smooth and continuous, so the stress is more evenly distributed, and the oval-shaped head is much less depth than the hemispherical head, easy to press molding, it is currently in the application of more low-pressure vessel closure one head.
