Problems that may be encountered for cutting fing fittings
1. Why does the cutting ring fitting leak?
A: Causes of leakage:
1. steel pipe is not topped to the positioning prism of the joint body, resulting in the cutting ring into the steel pipe is not enough to form a sealing line;
2. workers are not installed according to the regulations: such as the end of the steel pipe is not vertical, the surface of the steel pipe has burrs, not screwed to the required number of turns, screwing more than the required number of turns;
3 installation process, the steel pipe is skewed resulting in uneven cutting ring, resulting in part of the seal line is not formed enough;
4 steel pipe size Small, steel pipe quality is not high.
2. Why is the installation of large size pipe fittings particularly laborious? How to install it with less effort?
A: 1 During installation, the steel pipe is skewed, resulting in uneven ferrule cut-in, leading to large friction in the tangential direction;
2 There is no oil smearing in the prescribed place; labor-saving methods: smear a little oil on the threaded part of the joint body, and smear a little oil on the contact surface of the cutting ring and 24 degree cone, and the contact surface of the ferrule and the compression nut.
