Supply Taian arched head

The thickness of the definitions of the standard head tube cap is not reasonable, mainly in the container and the head after forming thickness requirements, convex head and the thickness of the thermal roll forming requirements shall not be less than the nominal thickness minus plate negative deviation (δn -C1), which may lead to the design and manufacture of twice increasing the thickness of the thickness on the basis of the design to ensure the forming thickness. Definition and labeling of such thickness is a popular method of international pressure vessel industry, has its rationality, but there are two problems need solutions Typically cap size is relatively small in our current standard, the head size is relatively bigger . Cap the ends of the pipe is generally used, head for the top and bottom (vertical device) container equipment parts or right and left edges (horizontal equipment) are generally outside diameter of the cap, like the elephant 219,273,325. Also known as plug cap, scarf, tube cover, bulkhead mounted on the pipe end male thread to cover plugging the pipe fitting. For closing the pipeline, the role and plugs the same, but the cap can be screwed directly on the tube, you do not need other fittings. Generally used for sampling the mouth of the tube does not end after the acquisition is complete, to screw on the cap, the other is in exceptional circumstances, after twist off the cap, you can wire port connected to tubes, continuous take temporary or priming. Tube cap generally lower pressure, easy removal for maintenance, under high pressure conditions generally do not cap. Cap includes a convex caps, cone shell, adjustable segment, flat lid and tighten port design. Cap parameters: Stainless steel: 304304L316316L321 Diameter: DN15-DN1200 thickness: SCH5-SCH160 standard: ASMEDINJISBSGB / TJBSHHG purposes: water, soft drinks, beer, food, petrochemical, nuclear power, machinery, medical equipment, fertilizer, shipbuilding, water treatment , piping, etc. Packing: wooden box, carton Service: providing technical advice, installation guide dish cap of r at avoiding splicing, will thinned, high stress. Generally, the head is the inner diameter, such as 1 meter, are referring to the inner diameter of the cap is not a requirement for the transition (unlike the standard oval), it can only be found on the diameter and length of the general manual, and straight edge Part longer. Just plug cap pipe, DN, will use more than 300 head replaced if the pressure to perform strength check. Caps and head shape almost made of stainless steel is more, cap size is relatively small and can be forged; head size is relatively bigger, usually with pressed steel, pipe caps are generally used for the ends of the pipe, head for up and down (Vertical devices) or left and right parts of the container device ends (horizontal equipment). Convex cap comprising: a hemispherical cap, oval pipe cap, disc and ball cap crown cap. From the perspective of the force gradually bad convex caps from the hemispherical cap, but the difficulty of making point of view, good manufacturing gradually. To this end, we have proposed the concept of a minimum thickness of forming: "; hot rolled or convex rear cylinder head forming process need to ensure the thickness, its value is not less than the design thickness."; That designer should be marked with a nominal thickness and forming the smallest thickness (ie design thickness δd) in the drawing, such that the manufacturing unit can decide whether thinning coupled with manufacturing based on the design and rounded amount of original design manufacturing processes.
