Q: What kinds of pipe joints can be divided into? What are the differences between the so-called one - piece pipe joint and other types of pipe joint?: Card sleeve type, welding type, flaring type, attached thread pipe joint, cone seal, flexibility, hand clamp, fast change, etc., the first three kinds are more used.

Q: The difference between the rubber pipe and PE pipe: The characteristics of the rubber tube has physiological inertia, UV resistance, ozone resistance, resistance to high temperature (-80 to 300), high transparency, strong resilience, resistant to compression permanent deformation, oil resistance, impact resistance, acid and alkali resistance, wear resistance, flame resistance, voltage, electric.

Q: What is a rubber core pulling method?: Hose core pulling for broken line and curve type pore channels, in addition to leaving the grouting hole and exhaust hole should also set the urinary bleeding hole, hole curve (line) to stay in the top hole, with the method of grouting hole.

Q: What does rubber soft joint "KDTF" mean?: It is a kind of pipe joint with high elasticity, high air tightness, medium resistance and weather resistance. The main outer layer, inner layer, intermediate layer reinforced polyester cord fabric, steel wire pressure protection layer.

Q: How to determine the tensile strength of GB rubber joint?: The tensile strength test specimen is dumbbell shaped and can be divided into 1, 2, 3 and 4 types, of which type 1 is universal, and the specific dimensions of each part of the sample are as follows:For non-standard specimens, that is, the maximum thickness of the narrow part of the sample taken from the finished product is specified as: type 1 is 3.Omm, type 2 and type 3 are 2.5mm, and type 4 is 2.Omm.

Q: Will the electric water heater be well connected with metal hose or hose?: For electric water heater, now the industry is required to use PPR pipe to its inlet and outlet for welding, on the one hand, long service life, can effectively prevent the water heater inlet and outlet leakage;

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.

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: Laboratory condensate water pipe must use rubber tube, shall not use latex tube reasons: Low temperature bending test at low temperature: hose clamp on rigid torsion wheel diameter hose diameter 12 times, for 6 hours at a low temperature, twisted 180 degrees within 12s when the measured torque and the standard temperature measured torque ratio. Low temperature bending: hose clamped in the diameter of the hose within 12 times the torsion wheel, parked at low temperatures for 24 hours, in the 10s to reverse 180 degrees, check whether or not the internal and external plastic brittle fracture and damage.

Q: How much is a gas hose a metre? At least 1 meters, 5 safe?: General 10 or so can be, the length of 1 meters to 1.5 meters can be, too short, unsafe, it makes sense.
