Cap Pipe Fitting

Pipe cap, also known as the head, plug, LIDS, pipe cap, cocks, welding on the pipe end or installed outside the pipe thread to cover wall pipe fittings.Use closed pipeline, function the same as the tube wall.Pipe cap including convex cap, conical shell, variable diameter section, the design of the flat cover and tighten.From the standpoint of stress, convex cap in the gradually from hemispherical tube cap is not good, but look from the manufacturing difficulty, good manufacture gradually.Stitching distance requirements, for more than 3 g, and not less than 100 mm (welding heat affected zone is high stress zone, and in the region will be a loss. The chemical composition of the final forming of welding seam detection level, scale and equipment shell, high waste.
Closure phase in the form of close, only the blind flange can be sealed, sealing, and welded tube cap is not detachable.Pipe cap including convex cap, conical shell, variable diameter section, the design of the flat cover and tighten.
Convex tube caps include: hemispherical tube cap, oval tube caps, disc pipe cap and QiuGuanXing cap.From the standpoint of stress, convex cap in the gradually from hemispherical tube cap is not good, but look from the manufacturing difficulty, good manufacture gradually.
