Introduction to practical application of pipe cap  

Cap manufacturers to introduce the practical application of pipe cap products, pipe cap in piping installation mainly used in the end of the pipe end this cap also use many of the products, such as pipe cap in some pipe head will have access to products, commonly used in the process of installing the connection mode is direct welding, the welding after the completion of our company staff will to carry on the fine polishing,  So that the pipe cap products are more beautiful in the pipeline, look special atmosphere.

Cap products in the customer's mouth also known as the head, but also become hemispherical cap, butterfly cap and so on.

To make tube cap products, we need to choose tube cap grinding tools:

The tensile die should be in good condition, and the vent hole of the upper die should not be blocked. It can be used only after being certified.

The upper and lower die and the pressing ring are respectively fixed on the punch and the press base with studs and accessories. The clearance of the circumference direction is uniform, and the difference is less than or equal to 1mm.

Before stretching each tube cap, check whether the tire mold is loose and offset, as well as other defects, and confirm that it is in good condition before continuing to use.

Before each product is drawn and pressed, it is necessary to remove the oxide scale, slag and other sundries on the workpiece surface of the tire mold, and evenly brush the pull ring with lubricant.  When cold drawing head, the upper and lower die and blank holder working face, the upper and lower parts of the blank periphery, are coated with lubricant.

The blank of the tube cap is pressed

In order to avoid corrugations and bulges during stretching of thin heads, the blank can be pressed into arch first.

The residual height of the welded joint of the splicing blank shall be polished until it is flush with the base metal before pressing.  When the plate is spliced, the distance between the outer weld and the center of the plate shall be less than 0.25DI and the width of the small plate shall not be less than 300mm.  (Di-- Inner diameter of sealing cap)
