Pipe thread mainly used for pipe connection

Pipe thread mainly used for pipe connectionPipe thread mainly used for pipe connections , its internal and external thread closely , there are two kinds of straight pipe with the cone . The nominal diameter is the diameter of the pipe connection , apparently a large diameter than the nominal thread diameter . Hydraulic fittings and pipe joints greatest common most significant difference is that the hydraulic pressure is great staggering, hydraulic tubing impact of sudden burst of oil is large.System Hydraulic ferrules blocking phenomenon is rare, common is sintered filters ( glass sand core ) blocked. Segmentation method for detecting occlusion using the system piping , from back to front loosen joints were checked and find blocked pipe , it should be immediately removed to dredge or replacement . Department began blocking obvious, constantly remain in the flow of particles in the pressure will slowly rise , and finally completely blocked. Pipe blockage will also see the joints or gaskets leak , low pressure better, high-pressure leaks evident. A sintered filter or filters ( pore size 2-10um) to remove particles blocking the pipeline ( eg 0.25mm diameter ) . Occlusion is a major failure of hydraulic pipe joints , pipe completely blocked , the pressure will Hydraulic hose fittings overpressure . If the length of the rigid blocking substances , such as biological samples biochemical substances ( proteins ) , microorganisms , fine metal wires can be turned on, the head can also be burned in the fire a burn , the organic carbonized , and then turned on. If it is a rigid material obstruction General to lead a very difficult problem , using the recoil approach can sometimes succeed. Can not be put on- line the same specifications of the tubes . If replaced with a new tube and then blocked , you should stop to check the above-mentioned several reasons causing obstruction . Operation, we need to protect the eyes and exposed skin , because the obstruction will be washed out at high speed . Is to turn around and pump tube erosion .
