阅读说明：本技术 一种抗扭抗弯防拉金属波纹管制作方法 (Manufacturing method of anti-torsion anti-bending anti-pulling metal corrugated pipe ) 是由 不公告发明人 于 2021-08-02 设计创作，主要内容包括：一种抗扭抗弯防拉金属波纹管制作方法,主要在金属波纹管件外表面包一层带有弹性塑料外管阴波内也要填充满。在阴波内填充满带有弹性塑料可以防止弯曲过程中管件破裂,因为每一个阴波波内都有弹性塑料增加了一定的阻力,在弯曲时有效把力分散开了,不会聚集到一二个波间从而可以防止弯管时把管件弯裂。因为每一个阴波内填充满带有弹性塑料在拉管时可增加反冲力和阻力使的管件不易拉直从面很好了保护管件的性能。抗扭也是一样当外管件阴波内填充满弹性塑料或软料时当扭曲时可增加反冲力和阻力从而有效的保护管件不会被扭变型,很好的保护管件不被破坏。(A method for manufacturing an anti-torsion anti-bending anti-pulling metal corrugated pipe is characterized in that a layer of elastic plastic outer pipe is wrapped on the outer surface of a metal corrugated pipe fitting, and the interior of a negative wave is filled with the elastic plastic outer pipe. Fill in the negative wave and be full of elastic plastic and can prevent that bending in-process pipe fitting from breaking, because all elastic plastic has increased certain resistance in each negative wave ripples, effectively dispersed power when the bending, thereby can not gather between two ripples and can prevent the pipe fitting bending when the return bend and split. Because each negative wave is filled with elastic plastic, the recoil force and the resistance can be increased when the pipe is pulled, so that the pipe fitting is not easy to straighten, and the performance of protecting the pipe fitting is good. The anti-torsion is also the same as the anti-torsion, when the external pipe element is filled with elastic plastics or soft materials in the negative waves, the recoil force and the resistance can be increased when the external pipe element is twisted, so that the pipe element can be effectively protected from being twisted and damaged.)

1. The anti-torsion anti-bending tensile, the negative ripples are filled and are fully had elastic plastic and can prevent that bending in-process pipe fitting from breaking, because each negative ripples is intraductal all elastic plastic has increased certain resistance, has effectively dispersed power when crooked, thereby can not gather and to the pipe fitting bending crack when can prevent the return bend between two ripples.

2. Because each negative wave is filled with elastic plastic, the recoil force and the resistance can be increased when the pipe is pulled, so that the pipe fitting is not easy to straighten, and the performance of protecting the pipe fitting is good.

3. The metal corrugated pipe comprises a metal annular corrugated pipe and a metal spiral corrugated pipe.

4. The corrugated pipe is covered with a layer of elastic plastic which is filled with negative waves.

Technical Field

The pipe fitting is mainly applied to a fuel gas conveying pipe fitting and a water pipe.

Background

The metal corrugated pipe fitting produced at present often appears in daily use, and brings hidden dangers of property and life safety belts for people. The produced pipe fitting can not be well protected in the mounting process and the using process, and the problems of pipe fitting strain, straightening, excessive bending fracture, distortion, torsional fracture and the like can be easily caused in the construction of non-torsion, non-bending and non-tensile strength. There is a considerable safety hazard.

Disclosure of Invention

The corrugated metal tubing is coated with a layer of elastic plastic and filled with the plastic, including the female bellows, as shown in fig. 1. The negative wave is filled with elastic plastic to prevent the pipe fitting from breaking in the bending process, and because elastic plastic in each negative wave increases certain resistance, the force is effectively dispersed when the pipe fitting is bent, and the pipe fitting cannot be bent and cracked when the pipe fitting is bent and can be prevented by gathering two negative waves. Because each negative wave is filled with elastic plastic, the recoil force and the resistance can be increased when the pipe is pulled, so that the pipe fitting is not easy to straighten, and the performance of protecting the pipe fitting is good. Is safer in use.
