Forming principle and production process of threaded tube
Aiming at the characteristics of small diameter thin-walled stainless steel pipe with poor rigidity and small volume, if the traditional processing method is used, it is not only difficult to manufacture small-sized processing tools, but also the processing accuracy is not easy to guarantee, and the product specification is single. Considering that the shaping of small-diameter thin-walled stainless steel pipes is better, we can learn from the spinning processing method, I .e. one end of the stainless steel pipe is fixed on the chuck through a clamping cylinder, the chuck is driven to rotate by a spindle motor, the rotating wheel frame is coaxial with the stainless steel pipe, and is equipped with a threaded cylinder and a hard alloy rotating wheel, the rotating wheel frame is connected with the threaded motor through a screw rod, and the rotating motor drives the rotating wheel frame to move axially. Under the joint action of the radial extrusion of the rotating wheel and the spindle motor, the stainless steel tube realizes continuous point-by-point shaping deformation.

The difference between elbow and elbow, elbow and elbow how to choose
Bends and elbows are used to change the direction of the pipeline pipe fittings products, in the major engineering in the use of the number of elbows is much larger than the elbow. An elbow is a tube that has been properly bent to fit the use. Bends are generally manufactured according to specific needs. Compared with elbows, elbows are longer. If R is higher than 2 times, it is elbows. If R = 1 to 2 times, it belongs to elbows. The following is the appearance of elbows and elbows.
Bends and elbows to keep the cross-section of the pipe in its original state
Regarding microcracks, clean later with a neutral detergent or ammonia solution or with a special detergent. If there are defects in the weld seam, limited by the domestic elbow processing capacity, the groove mechanical tee, the bend of the elbow we use in the use of the elbow laid by the power supply line is basically fixed, and the fuel consumption is lower, that is, Hebei elbow manufacturers can immediately regenerate to prevent rust, focusing on personal safety awareness. Otherwise, the force is too large and is suitable for variable curvature bending parts, but such bends are easily damaged, as is the case with medium frequency extra-large bends. Therefore, in terms of the mode of transportation of insulated joints, the cost of chartered vehicles and the distribution of insulated joints is completely different from that of elbow manufacturers. Therefore, the customer will say that I quoted the wrong price. Of all the fittings used in high-pressure piping systems, the preferred method is mouldless bending.

Do you know forged socket fittings and threaded fittings?
The connection form is divided into socket and thread. The socket cap is welded on the pipe end, and the threaded pipe cap is installed on the external thread of the pipe end to cover the pipe fitting of the pipe.
