Q:Plastic metal hose connector model specification, who knows?

Package type plastic hose is many, the most common is the DPJ thread joint, DPN joint, DKJ card connector, DGJ self fixed joints, Glenn joints, fittings

Q:What's the rubber sleeve of the expander?

Expansion rubber flexible joint, installation of the flange sleeve telescopic device.

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:What should I pay attention to when rubber tube is in storage?

Storage should be as follows: (1) should be stored in a ventilated and dry environment, the relative humidity of the air is 50% ~ 80%. (2) should be stored in non corrosive media, and away from the heat source, the temperature is about 5 degrees Celsius conditions. (3) packing should be kept as far as possible without box stacking.

Q:Why can the air conditioning connection be made of copper tube? How about rubber tube and aluminium pipe? Please heroes pointing for the dishes.

The pressure of the aluminum pipe is relatively small. "Again, when the aluminum pipe is too soft, it is easy to be flattened.".. Rubber tubes will decay if they are used! Withstand pressure is also high!

Q:Why should liquefied petroleum gas use strong rubber hose and liner?

Commonly called liquefied petroleum gasMain ingredients: ethylene, ethane, propane, propylene, butane, butene, etc. (oil resistance will accelerate swelling and aging).Appearance and properties: colorless gas or yellow brown oily liquid, has a special odor.In order to remind people of the leakage of liquefied petroleum gas in a timely manner, the processing plant often mixes a small amount of foul odor mercaptan or thioether compounds into liquefied petroleum gas, which is the source of special odor.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!

Q:How to prevent leakage of rubber joint check valve?

Is an integral structure, one hundred percent high quality elastic rubber material, built-in reinforcing fibers, except hooped external stainless steel hoop, its interior does not contain any metal accessories, will not rust corrosion, and wear resistance strong, no mechanical failure worries, no maintenance. Because it is used in butyl rubber, so that the wear resistance is particularly strong with the traditional water pressure automatic opening and closing are very safe and reliable, no noise, no need of manual operation, so no need to maintain his application scope is wide.

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:What is the function of the rubber pipe joint and the installation 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:Is it feasible to use rubber material, middle canvas layer and outer rubber material in PVC rubber tube?

Cloth rubber tube, 68.5MM mold out, take off the mold, after natural cooling, measuring the diameter of only 67.8MM, rubber and cloth shrinkage!
