Characteristics and main uses of pipe cap  

Cap features: Caps come in many forms.  Its role is to seal.  One is to make the upper and lower bottom of the can-shaped pressure vessel, and the other is that the pipe is at the end and is not ready to extend forward, so a head is used to seal the pipe in the form of welding.  Similar products to the head are blind plates and tube caps, but those are removable.  After the head is welded, it can not be disassembled.  The supporting fittings are pressure vessels, pipes, flanges, elbows, tees, four-tees and other products.  

 Material introduction of tube cap: Carbon Steel:  ASTM A105, 20 #, Q235, 16 mn, ASTM A350 LF1, LF2 CL1 / CL2, LF3 CL1 / CL2, ASTM A694 F42, F46, F48, F50, F52, F56, the F60, F65, F70, etc  

 Alloy Steel:  ASTM A182F1, F5a, F9, F11, F12, F22, F91, A182F12, A182F11, 16MnR, Cr5Mo, 12Cr1MoV, 15CrMo, 12Cr2Mo1, A335P22, ST48.8/ⅲ, 35CrMoV,  45 crmo etc.  

 Stainess Steel: ASTM A182 F304, 304L, F316, 316L, 1Cr18Ni9Ti, 0Cr18Ni9Ti, 321, 18-8 etc  

 The cap includes convex cap, conical shell, reduced diameter section, flat cap and different design of tightening orifice.  Convex pipe cap includes: hemispherical pipe cap, oval pipe cap, disc pipe cap and dome pipe cap.  From the point of view of force, convex pipe cap is gradually bad from the hemispherical pipe cap, but from the point of view of manufacturing difficulty, gradually good manufacturing.  

 The processing method of the tube cap mainly uses the advanced equipment press machine to put the tube blank into the mold, and the upper and lower mold is pressed. Under the push rod, the tube blank moves along the inner membrane and the gap reserved for the outer mold and completes the manufacturing and forming.  

 The purpose of the
