What are features of cutting ring connector?
Connector of cutting ring type has the card by tighten nut tightening in joint set of 24 ° cone, at the same time in the card sets of biting steel pipe to form effective hard contact seal, connector of cutting ring type has the biggest characteristic is installed is very convenient and only a wrench to install, use elastic card set of sealing ring , can further improve the ability of connector of cutting sleeve type has the leakage resistance: the other is not relative to the welded joint It will pollute the pipeline cleanliness due to oxide scale in the installation process, so the jacketed joint is widely used in high and low pressure common pipeline system, but the jacketed joint requires the use of precision seamless steel pipe. Flaring joints are recommended if precision seamless steel pipes are not used.
1. The steel pipe is sawed vertically. The perpendicularity error between the end face and the axis of the pipe is allowed to be ±3°.
2. At the end of the steel pipe, the inner and outer surfaces should be slightly deburred, with a permissible chamfering of 0.2×45°.
3. For elbow, the length from straight end to bend should be at least twice the height of nut
Jacket pre-installation:
in order to ensure joint installation effect, it is recommended to use pre-installed joint body or other corresponding pre-installation.
Equipment is pre-installed and assembled through pre-installed joint body:
Apply a small amount of grease to the threads of the nut, to the threads and cones of the premounting body, and to the jacket. Please use special grease ASW 040 P2 for stainless steel joints. Push the nut and clamp onto the steel pipe and make sure the clamp is not reversed
The steel pipe pressure inside the pre-installed joint, joint nut screwed into pre-installed with the hand, and then using a wrench, tighten, until the card hold steel pipe, then will feel tight force increases, and then continue to tighten nut with a wrench is about 1 1/4 to 1 1/2 circle, for larger Φ 12 mm above specifications of steel pipes with a longer spanner.
