The use and classification of high pressure pipe fittings
High pressure pipe fittings are suitable for high pressure steam machinery and equipment, ultra-high pressure and high temperature pipelines in chemical plants, high pressure vessels in power plants and nuclear power plants, boiler accessories and other harsh environments. Pipe fitting is the pipeline system software plays a connection, manipulation, phase change, drainage, sealing and promote the role of parts in general.
Application classification of high pressure pipe fittings
1. The high-pressure pipe fittings used for pipeline connection include flange, tee joint, pipe clamp, sleeve joint, etc.
2. Change the direction of the pipe High pressure fittings: elbow
3. Change the high-pressure pipe fittings of pipe: reducer (eccentric reducer) and reducing elbow
4. High-pressure pipe fittings of lifting pipeline branch system: three-way and four-way
5. Pipe fittings for pipeline sealing: sealing ring, raw adhesive tape, linen, flange blind plate valve and pipe plug
6. Pipe fittings for fixing pipes: circlip, hook, metal ring, fixed bracket, fixed bracket, pipe clamp, etc.
According to the connection mode, the pipe fittings can be divided into four categories: sleeve specification pipe fittings, screw tooth pipe fittings, flange pipe fittings and electric welding pipe fittings.
Application Countermeasures and Precautions of Stainless Steel High Pressure Pipe Fittings
When using maintenance and stainless steel high-pressure pipe fittings, there are many problems that need to be paid attention. The reference standards for the application countermeasures and precautions of stainless steel high-pressure pipe fittings are as follows:
1. Stainless steel high-pressure pipe fittings stored for a long time shall be inspected as planned. Always keep clean, clean exposed appearance, remove stains, store neatly in a naturally ventilated area, prohibit stacking or outdoor storage. Persistently dry and naturally ventilate stainless steel high-pressure fittings, clean machinery and equipment, and store them according to accurate storage methods.
2. When the equipment is running, the stainless steel elbow can be installed on the pipeline immediately according to the interface mode, and the machine equipment can be implemented according to the application site. In general, it can also be used in all parts of the pipeline, but it needs to be easy to operate. Pay attention to disconnect the stainless steel elbow platform flow material needs to flow above under the vertical gate valve, and the stainless steel elbow can only be vertical machinery and equipment. The stainless steel elbow in the machine equipment shall be sealed to prevent large-scale leakage and endanger the normal operation of the pipeline.
3. Stainless steel elbow gate valve, stop valve, stop valve in use, only open and close, can not adjust the flow, to prevent erosion of the protruding surface, accelerate the damage. The stop valve and upper thread stop valve are equipped with back sealing equipment, and the top of the valve is fixed with the main shaft to avoid leakage of substances at the filling point.
4. Make stainless steel elbow with spindle. Try not to use bars or other special tools to prevent damage to the gate valve components. Rotate the spindle clockwise to turn off, and vice versa.
5. The anchor bolts in the filling material cover of the stainless steel capillary valve should be balanced and tightened, and should not be pressed into the bending situation to prevent touching or affecting the movement of the valve seat or causing leakage.
6. Stainless steel elbows should be kept clean in use. The screw teeth of the transmission system need to be successfully implemented according to the plan. Once common faults are found, they should be stopped immediately and the fault phenomenon should be found out.
