Upsetting straight thread process is to use steel cold heading machine ends upsetting, and then machined straight sets of silk threads on the ends of upsetting the steel segment, and then connect the two steel butt sleeve. Due to the ends of the steel cold heading,Parher jic female swivel fitting not only to increase the cross-section;Hydraulic pipe fittings and strength have improved. Additionally, the ends of the processed steel straight thread, the smallest diameter of the thread at the bottom, should not be less than the diameter steel base metal. Therefore, Jic nipples with reinforced base materials, such as strong. Process and other steel straight thread connection is:
Reinforced hydraulic upsetting material → → → threading threading the mounting sleeve → → → hydraulic upsetting reinforced plastic protective cover installed U-turn → → → on-site installation and marked.
Reinforced ends must use straightening process,quick hose coupling requiring incision and reinforced cross section perpendicular to the axis, as cited only use abrasive cutter cutting its length by cutting the length of the ingredients. Reinforced by upsetting upsetting to realize the function of automatic clamping, upsetting other processes, upsetting the first time about every 30 ~ 40s, each class of about 500 to 600 upsetting, upsetting the first operation is very simple. Upsetting machine weighs only 380kg, transported to the site to facilitate processing. Prior to the formal process should be based on bar diameter and hydraulic machine performance and appearance after upsetting effect, the test to determine the appropriate upsetting pressure.
