Q:Hot tap water pipe joint leakage, what method can be repaired?
Also can use glue, glue in general, more suitable for low pressure pipeline, operating pressure should not exceed 4 kg, this method is not suitable for PP-R products, because the PP-R material determines the glue is generally difficult to dissolve.
Q:How about the water pipe fittings and millimeters?20mm is 425mm is 6Why
This is the confusion caused by the confusion of the three conceptsA,4 points, is commonly known as, should be 1/2 inches,.4/8 is 4 copies6 points, 3/4 inches,.6/8 is 6 copies
Q:Maintenance skills of fire hose clamp joint leakage
The best approach is to remove the clamp groove on the inner wall of the groove, cut a layer of 3mm thick rubber (or thin rubber inner tube), the inner wall of the groove width is smaller than the width of about 2~3mm, their good after the clamp bolt is good, no Water Leakage the problem.
Q:Press the hydraulic pipe fittings standard need to do what procedures
The corresponding micrometer scale is 3. Installed with 33mm mold on the mold seat, and rotated to 3 micrometer scale, the hose peeling and joint assembly. After measuring the joint outer diameter of buckling is buckling parameter table after withholding value 33.5mm is withheld. If the diameter does not conform to withhold, after a fine micrometer withhold hose. Withhold hose connector: swage size too much, hose layer broken, causing leakage; too little buckling size, and hydraulic oil spill caused by rushing out of joint.
Q:Hydraulic pipe quick coupling principle of hydraulic pipe joint
JB/T6381 ~ 6385-1992 burking hose connector has the advantages of convenient installation, but added a tightening process. After the hose is damaged, the joint coat can not be reused, and it is made up of a steel wire braided hose. The utility model can be connected with a welding pipe joint sealed with a O ring. Pipeline system suitable for oil, water and gas as medium. Medium temperature: Oil: -30 ~ 80 degrees Celsius; air, -30 ~ 50 degrees Celsius; water, 80 degrees below JB/ZQ4427 ~ 4428-1986, three valve type hose joint assembly, do not need to remove the rubber tube of the outer layer. A slightly different diameter of hose hose, hose on the joint coat of pre compression to compensate. Hose pre compression in 31% ~ 50% range to ensure no leakage under the pressure of work, will not pull glue, cover does not break. With the welded pipe joint, quick joint, sleeve type pipe joint used for oil, water and gas pipeline system for medium, working pressure, medium temperature by connecting hose limited JB/ZQ4429 ~ 4431-1986 quick change connector (both open and closed) tube apart and self sealing pipe. In the liquid will not be lost, so it is suitable for frequent disassembly occasions. The structure is complex, and the local resistance loss is greater. Suitable for oil and gas pipeline system for medium, the working pressure is lower than 31.5MPa, the medium temperature of -20 to 80 DEG JB/ZQ4434-1986 quick change connector (both ends open) for oil and gas pipeline system for medium, the working pressure of medium temperature according to connecting hose limited JB/ZQ4435-1986
Q:What does pipe joint "DD" mean?
Parts that work in a weak corrosive environment, such as covers, bearings, valves, hand wheels, etc., are joined mainly for connection, installation and maintenance.
Q:What is the function of the pipe joint?
Hydraulic term is a part of a hydraulic system that connects the pipe or sets the line to the hydraulic element
Q:110 degree PVC pipe joint
PVC (full name Polyvinylchlorid) for polyvinyl chloride, in addition to other ingredients to enhance its heat resistance, toughness, ductility and so on. The top layer of this surface film is lacquer, the main component is polyvinyl chloride, and the bottom layer is coated with adhesive. It is a very popular, popular and widely used synthetic material in the world today. Its global usage ranks second in various synthetic materials. According to statistics, only in 1995 a year, PVC production in Europe, there are about five million tons, while its consumption is five million and three hundred thousand tons. In Germany, PVC production and consumption averaged one million and four hundred thousand tons.
Q:How to identify the pipe joint thread quickly and accurately?
1 use a thread gauge to check the gauge of the pipe joint, which is the most accurate.2, you can also use special tools, taps (for female pipe joints) and wrench (for pipe fittings), which is a tool for making pipe joints. Try it on and see if it's easy to screw in. If it is easy to screw in, you can determine the specifications of the unknown pipe thread according to the specifications of the known taps and wrench marks.
Q:What joints do nylon hard tubes work on?
(two) clamp sleeve type pipe joint;Application: sealing pipe joint oil, water, gas and other non corrosive or corrosive medium, with plastic pipe specifications are flexible, and pipeline connection, has the characteristics of reliable connection, good sealing performance, so it is widely used in oil refining, chemical industry, light industry, textile, metallurgy, national defense, aviation, ship the system is suitable for all kinds of hydraulic transmission; mechanical engineering, machine tools and other equipment pipeline. Sleeve type pipe fittings manufacture standard following fifteen kinds:1, card sleeve end through pipe joint (GB/T 3733-2008)2, sleeve type cone thread straight pipe joint (GB/T 3734-2008)3, card sleeve type end through long pipe joint (GB/T 3735-2008)4, long taper pipe thread joint (GB/T 3736-2008)5, card sleeve straight through pipe joint (GB/T 3737-2008)
Our company adheres to the corporate mission of "create a boutique fittings, achievement and customer desire to stimulate social development", upholds the core values of "integrity, innovation, efficiency, responsibility", and sticks to the philosophy of "honesty, cooperation, win-win cooperation. We welcome friends at home and abroad to work together with us based on win-win development.
