API 7K High Pressure Cementing Hose
hose assembly Purpose of armor:
1. Prevent the hose from being damaged by collision or mechanical friction.
2, increase the insulation layer, can be used in high temperature environment to improve the service life.
The structural form of the armored hose: Type K: Add insulation to the outer layer of the hose.
Type K1: woven wire mesh sleeve on the outer layer of the hose.
Type K2: Add insulation material to the outer layer of the hose, and then woven the wire mesh sleeve.
Connector type of armored hose: The joint form of the armored hose is identical to the joint and code of the high pressure hose assembly.
Marking method for armored hose assembly: The method of marking the armored hose assembly is to mark the structural form of the armor on the basis of the marking method of the high-pressure hose assembly.
