summary<\/h2>\n

 <\/p>\n

The reinforcement taper thread joint is a joint that processes the connecting end of the reinforcement into taper thread and connects the reinforcement into one according to the specified torque value by using the principle that the taper thread can bear both tensile and compressive forces and has good self-locking and sealing performance.<\/p>\n

The basic idea of GK equal strength reinforcement taper thread joint is: before cutting the taper thread at the reinforcement end, first apply great pressure on the reinforcement end through the pressing die along the radial direction to make it plastic deformation and form a conical pile, and then cut the taper thread at the preloaded reinforcement end according to the process route of ordinary taper thread reinforcement joint, Then use the steel sleeve with internal taper thread to tighten the connection with a torque wrench. During the plastic deformation of the steel bar end, according to the principle of cold work hardening, the strength of the deformed steel bar end material is 10% ~ 20% higher than that of the steel bar base material, so that the strength of the tapered thread cut on it is also increased accordingly, which makes up for the defect of the reduction of the joint bearing capacity caused by the reduction of the section size of the steel bar base material due to the turning of the thread, Thus, the strength of the conical threaded joint is greatly improved, so that it is not less than the strength of the corresponding reinforcement base metal. Because the strengthening length is adjustable, the weakening of the root of the threaded joint can be effectively avoided. Without relying on the super strength of reinforcement, the strength requirements of the most advanced class I joint in the industry standard can be met.<\/p>\n
