Q: Hydraulic hose joint dimensions: Metric plain thread1. metric screw thread with a capital M, tooth type angle 2 degrees =60 (alpha tooth type half angle);2. metric ordinary thread by pitch, coarse teeth, ordinary thread and fine teeth, two kinds of ordinary thread;2.1. coarse tooth ordinary thread mark generally does not indicate the pitch, such as M20 means coarse thread; fine tooth thread mark must indicate the pitch, such as M30 * 1.5 for fine tooth thread, in which pitch is 1.5.2.2. common thread is used for the connection and fastening between the mechanical parts, and the general thread connection is mainly made of coarse thread. The thread strength of the fine tooth thread is slightly higher than that of the same nominal diameter, and the self-locking performance is better.Mark 3. metric screw thread: M20-6H, M20 * 1.5LH-6g-40, where M represents a common thread metric, 20 nominal diameter thread is 20mm, 1.5 pitch, LH said, 6G 6H left, said thread precision grade, precision grade of internal thread uppercase, lowercase precision grade of said external thread, 40 screwing length.

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: Why should the high pressure hydraulic tube peel off the outer skin?: High pressure hose is generally relatively thick, there are steel wire layer, the purpose of peeling is to connect the tooth and steel layer close combination, the joint is more solid. But not all high-pressure hose needs peeling. Now many large companies do not need peeling. For example, pike.

Q: What is the function between the rubber pipe joint and the installing pipe?: The action of the rubber pipe joint on the installation of pipes:1. Small size, light weight, good elasticity, easy installation and maintenance.2. After installation, the transverse, axial and angular displacement of the pipe vibration can be absorbed. The pipe is not concentric and the flange is not parallel.3 、 after installation, it can reduce the noise caused by vibration of pipes, pumps and so on, and has strong vibration absorption ability.

Q: Plastic metal hose connector model specification, who knows?: There are hoses, hoses, hoses, fittings, and steel tubes, with specifications ranging from 8 to 150

Q: Can the rubber hose for the LPG cooker and gas cooker be general?: The rubber hose for the gas cooker and the gas cooker can be used as long as the size is the same.

Q: Three yuan ethylene propylene rubber hose, hydraulic oil and oil?: Finally, NBR (Ding Jing rubber), ACM (acrylate), FKM (FKM) can be non polar medium.

Q: What are the methods of sterilizing rubber hoses and Perspex?: The rubber tube is directly into the steam sterilizer. After a few cracks, throw them away and use the new ones.

Q: How often do the oil - resistant rubber pipes undergo atmospheric pressure testing?: Suction flat test: in the 1min vacuum, after maintaining 10min, with diameter of 0.9 times the diameter of the hose rolled over, check the degree of collapse of the hose. Some standards used to measure the rate of change in the outer diameter of the hose to indicate the extent of deformation of the hose.

Q: Are the bridges, bellows and rubber tubes drawn out or are they drawn only? And the bellows are tensioned with the steel strand?: It is relatively rare, usually corrugated pipe for zinc metal corrugated pipe, the construction unit may be in order to prevent pipe blockage, when pouring concrete, the corrugated pipe with rubber tube, after pouring completed final setting, you can pull out rubber tube. Bellows need not be drawn.
