Q: How to determine the parker381 hose joint?: PARKER hose connector specifications: 1/4 "to 2", the connection form of DKO 24 cone, American NPT taper thread, JIC37 degree flared, ORFS American plane seal, JIS60 cone, JIS30 degree flared, SAE flange etc.. It can be divided into three series: detachable, buckle pressing and Push-Lok. The detachable series hose joint does not need special equipment when it is assembled, so it is easy to operate. It is especially suitable for field operation and can be reused. But because of the high price, fewer customers are used. Buckling type series high voltage because the connection is reliable and widely used, but the processing assembly need to withhold special equipment, so the majority of customers directly buy hose assembly. Push-Lok series are suitable for low voltage applications. They are widely used in automobile production lines because of their rapid assembly and disassembly, easy maintenance and replacement. They are also widely used in the die industry.

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?: The pipe joint is divided into a steel pipe joint and a hose joint.The steel pipe joint is provided with a clamp sleeve type, a welding type, a clapboard is connected, a reducing connecting, an oil inlet connection, a combined connection, a pressure gauge connection, a flange connection, etc..A seizure type hose connector, removable, plug-in, you said one pipe joint is extruded hose connector, connector and sleeve is one, there is a separate.My side is to do this piece, the United States PARKER Parker hydraulic hose, joints, assembly, quick change connector.

Q: There are several ways to connect the built-in rubber stop: Generally, there are two kinds of joint methods for this kind of rubber sealing strip: one is to use adhesive to make cold joint, and the other is to use hot vulcanizing mold to heat it.

Q: Latex tube, rubber tube, silicone tube, which three of the best tightness?: Ding Ji rubber: usually used as a silicone hose material used, in general, the sealing ability of silicone hose is better than the rubber hose. So, in life or in the industry need to seal the tube will take into account the silicone hose.

Q: What is the maximum pressure that a hose can bear?: This hose with material, wall thickness, diameter is Dudu, but there are special hose pressure testing machine test the size of the market, you take a look at the next.

Q: What happened to the soft rubber flat?: A slightly heated or pressurized medium will return to its original condition.

Q: The basic buret is a rubber tube is inlaid with a glass bead to replace glass piston. Why this burets cannot be used to install Potassium Permanganate solution?: Are made of glass, acid burette glass piston burette, no piston, just at the tip of a rubber tube, rubber tube with glass beads, glass or the lower beak. Why not the same because of acid burette, glass and alkali reaction, generate silicate, sticky, if it is very easy to use acid burette, the hole is blocked, damaged burets.

Q: How to detect the reliability of rubber hose: 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. Test of low temperature brittleness measurement hose is the most simple specimen should be bent 90 degrees at low temperature, or a hose after freezing compressed 1/2 to see whether the embrittlement, another method is to use a certain weight of the heavy hammer falls freely, to see if the specimen embrittlement impact specimen.

Q: The use of anti slip rubber joints under what circumstances?: When the pipeline medium for acid, oil, high temperature and other special materials, should be higher than the pipe work pressure, a gear of the joint.

Q: M40 and M50, and then the hose is 2 "what does the box connection mean?": One with teeth and one with hose, the hose is 2 inches, 2 inches of hose, and the inner hole is 50MM (1 inches =25.4MM).
