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: Latex tube, rubber tube, silicone tube, which three of the best tightness?: Rubber tightest is butyl rubber, rubber pipe products in general, with no fiber layer, expanding 300-500% is no problem, you can put it into the glass tube, depends on the strength of the glass tube and technique.

Q: What is the maximum pressure that a 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: What's the cause of a default like a general rubber product?: Measures to prevent aging: from the point of view of aging, one of the main reasons is the polymer structure itself. Therefore, it is important to improve the structure of polymers to improve their aging ability. For example, in rubber vulcanization, there are still unsaturated double bonds, and rubber products in use and it is difficult to avoid the erosion of sunlight, oxygen, ozone, so people on the synthesis of new varieties, to avoid or reduce the polymer chain of rubber double bonds, such as ethylene and propylene two monomer by copolymerization made two yuan B two rubber, different from other synthetic rubber is one of the major characteristics in the structure of the backbone is not completely saturated with double bond, making it the most ozone resistance, chemical resistance, high temperature resistant rubber aging; there is a kind of antioxidant, such as adding oxygen or ozone to prevent aging caused by antioxidants. Add UV stabilizers, heat stabilizers, preservatives and other unfavorable factors, and caused by aging.

Q: How to distinguish the true and false corrosion resistant rubber soft joint?: Put the rubber joint in the corrosive liquid which needs to pass. One day, 24h can see that the swelling ratio is not more than 5%!

Q: The difference between silicone tube and PVC tube: Silicone hose is also a kind of rubber tube, resistant to oil and heat. Because of the different types of rubber rubber pipe has many applications, commonly used rubber tube material EPDM, CR, VMQ, FKM, IIR, ACM, AEM, common structure with single, double, multilayer, enhanced, non enhanced etc..Silicone hose is the biggest feature of resistance to temperature changes of -60 degrees to 250 degrees, but the cost is very expensive, PVC is often used as ordinary water pipes, temperature sensitive, cheap and delicious, suitable for general working environment, no requirement for hoses. Compression resistant silicone hose can also withstand pressure, PVC in general, depends on the wall thickness and caliber. These are the differences between the silicone tube and the PVC tube.

Q: Hydraulic hose joint configuration: Strong uplift: hose connector is composed of a core tube and sheathed and clamped together with the sleeve, the sleeve is divided into two sections, the first section length is less than second and greater than the outer diameter of section second; the core tube is divided into two sections, the first section is the second section is the joint oil, rubber press section; the core pipe and the sleeve rubber press section cooperation is divided into three parts. The first part is a locking part, the second part is the part of the third part is the steel wire buckle, rubber press sealing parts; in the first part, the outer surface of the core pipe has a clamping groove, the sleeve surface along the circumferential direction with a snap ring matched; in the second part, the core tube the outer surface of a step and a groove, the inner surface of the sleeve ring a match; in the third part, the outer surface of the core pipe is provided with at least two corrugated groove, the sleeve surface is provided with at least two teeth groove. The utility model is used for the steel wire woven hose made of inner rubber layer, steel wire layer and outer rubber layer, and has the advantages of excellent pull proof performance, long service life and good sealing performance.

Q: How should we distinguish between the silicone hose and the rubber tube?: Smell, silicone no flavor, rubber flavor, silicone general flexibility better, rubber mechanical better

Q: Laboratory condensate water pipe must use rubber tube, shall not use latex tube reasons: 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: How much is a gas hose a metre? At least 1 meters, 5 safe?: About 10-20 yuan. Purchase gas hose produced by manufacturer of production license. It is recommended to be used for not more than 3 years.
