Q:The small hose attached to the grease gun is coarse or fine at the joint
For sealing, according to the maze principle, the smaller the pitch, the number of threads, that is, the more layers, the better the sealing effect, not easy to leak oil, significantly better than the rental thread.
Q:Stainless steel metal hose and flexible rubber joint which is easy to use?
Stainless steel metal hoses and flexible rubber couplings are used for pump inlet and outlet to absorb vibration and noise during the operation of the pipe pump. The two products are common in the case of ordinary media.
Q:Method for inserting glass tube into rubber tube when assembling instrument
Pipe connection is widely used in the laboratory. Besides the sleeve of the glass tube, there are plastic tube, rubber hose and iron pipe sleeve, etc. the sleeve connection method can be carried out by referring to the sleeve connection method of the glass tube.
Q:How to make sure the rubber hose will not be worn off?
The ink jet machine can mark the laser marking machine on the pipe, and then mark the joint on the joint
Q:Flexible rubber joints. What do they mean by flexing?
Flexible flex is simple to understand and relatively flexible in rubber joints. Stainless steel bellows and flexible rubber joints do not belong to the same kind of products, but they are more flexible and stable because of their axial expansion performance, so they can replace flexible rubber joints.
Q:Why should liquefied petroleum gas use strong rubber hose and liner?
These gases on the rubber has a certain corrosion, swelling (not resistant to oil will speed up swelling), aging effect, liquefied petroleum, so choose rubber seal to consider oil resistance, corrosion resistance, swelling. Petroleum gas is corrosive to ordinary rubber pipes and gaskets and easy to cause air leakage. Therefore, it is necessary to use rubber pipes and gaskets with strong oil resistance.
Q:Could you tell me the maximum pressure that the hose can bear?
Production process with pressure hose hose to withstand the enhancement layer material has a great relationship with the enhancement layer, the enhancement layer of the same level, generally the larger diameter bearing capacity is small, the enhancement layer is cloth or steel wire line and the enhancement layer is also different. Select the hose you want according to your requirements. The hose pressure is 4 times the normal pressure
Q:Is the electric water heater well connected with the metal hose?
The electric water heater, now in the industry are required to use PPR on the inlet and outlet pipe welding, a long service life, can effectively control the water heater outlet Water Leakage; on the other hand, can avoid the water heater power switch for two grounding and frequent take-off effectively. Therefore, the metal pipe connection does not meet the safety and installation specifications
Q:Difference and application of rubber joint and rubber expansion joint
The utility model can be used to reduce the vibration and noise of pipelines, and can compensate for thermal expansion and cold contraction caused by temperature changes. Rubber expansion joints are used in chemical, construction, water supply and drainage systems!
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;
