Q: How do you get the joint of the plastic pipe?: It adopts electric melting connection, which is suitable for PE water supply pipeline with big caliber inside and outside.

Q: Does the rubber tube affect the engine in the car's tank?: I don't know what you mean by that, but the car's tank itself needs to be sealed and no clutter is allowed

Q: Is the electric water heater well connected with the metal hose?: On the other hand, the utility model can effectively avoid the frequent switch of the water heater power switch because of the two grounding. Therefore, the metal pipe connection does not meet the safety and installation specifications.

Q: How do the rubber tubes fit into the galvanized pipe?: If the rubber tube is outside the galvanized pipe, when the rubber is ordered, the inside diameter shall be greater than the outer diameter of the galvanized pipe. If the rubber tube is inside the galvanized pipe, when the rubber is ordered, the outer diameter of the rubber pipe will be galvanized and the inner diameter of the galvanized pipe will be inside

Q: Is flexible rubber joint and telescopic device a kind of thing?: The utility model discloses a pipe expansion device, which is a connecting piece which is compensated by the size change caused by thermal expansion and cold contraction in the pipe connection. There are two kinds of pipe expander, one is rubber pipe telescopic device, and the other is metal pipe telescopic device.

Q: What is a hose valve?: It is composed of valve body, headstock gear and special rubber tube. When working, turn the handwheel in clockwise direction, which can achieve throttling and closing.

Q: Is it feasible to use rubber material, middle canvas layer and outer rubber material in PVC rubber tube?: Improvement measures: 1, adjust the process, plastic material in place; mixing rubber plastic stability; vulcanized rubbing with low temperature long time vulcanization; 2, test cloth in curing temperature shrinkage coefficient is too big, consider changing cloth;

Q: What's the rubber sleeve of the expander?: The expansion device is also called expansion joint, expansion joint, compensator and expansion joint. The expansion device is divided into steel telescopic device, rubber telescopic device and stainless steel telescopic device according to the material. Expansion device capable of axial expansion in a certain range, the offset can overcome different axial pipe butt within a certain angle and produce, installation and convenient disassembly pipeline valve greatly, in the pipeline to allow expansion in free expansion, once over its largest expansion amount rise to limit, to ensure the safe operation of pipeline the. Mainly for the protection of the safe operation of the pipeline, has the following functions: compensating absorption pipeline axial and transverse and angular deformation; absorption equipment vibration, reduce the vibration on the impact of pipeline equipment; deformation of the pipeline, absorb seismic subsidence.

Q: The use of anti slip rubber joints under what circumstances?: The flange connecting the rubber joint shall be the valve flange or the flange conforming to GB/T9115.1 (RF).

Q: Is the rubber pipe joint installed in the middle of the pipe and pump for shock absorption?: Control the noise produced by parts of machinery, equipment, and equipment. The pump foundation of the new pump house should adopt heavy weight to prevent vibration from producing noise. Vibration isolation should be set up with rubber vibration isolating pads to reduce vibration noise. Each pump unit shall be provided with a foundation to prevent resonance. Use "soft" connection as far as possible in the suction pipe and pressure pipe of the pump. Periodic maintenance problems, such as packing leakage, equipment parts loose, serious wear and tear of equipment parts, mechanical vibration and so on, should be repaired in time, thereby reducing noise.
