- Q:What are the types of hydraulic couplings?
- Mechanical design manual fourth volumes, hydraulic pipe joints are there?. You go check it out,.
- Q:Plastic pipe joint leakage, how to deal with better?
- Repair seal.Specific operation, see the following points:Now that the water leaks, you'll find the main switch for this pipe and turn it off for later maintenance;
- Q:Do you need adhesive for the sleeve joint of PVC wire pipe?
- The Construction Code stipulates that this is true, but it is rarely used in general decoration.
- Q:What's the difference between the half pipe joint and the branch seat?
- The main body of the branch pipe is made of high quality forgings. The material is the same as the pipe material. Carbon steel, alloy steel, stainless steel and so on. The branch pipe and the head adopts a welding, pipe seat and branch pipe or other pipe (such as tube plug, etc.), instruments and valves connected with butt welding, socket welding, threaded types.
- Q:What is the size of the PVC pipe joint?
-  the PVC joint size is in inches, 1 inches =25.4 millimeters. PVC: polyvinyl chloride (English: PolyVinyl Chloride abbreviation: PVC) is a use of a chlorine atom to replace one of the hydrogen atoms in polyethylene polymer material. PVC is an amorphous white powder with less degree of branching
- Q:How do I distinguish the rigid clamp joint and the flexible clamp joint from the outward appearance?
- Length and thickness of flexible clamps.Clamp itself difference:Flexible and rigid joints of the same specifications: width is different, flexibility is wider than rigidity 2MM (take 159 clamps as an example)
- 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 is the liquid used in the fire hose joint?
- The commonly used red is the pipe interface glue, and the white is the liquid raw meal belt
- 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:PPR pipe joint leakage, do not want to change pipes, what is the good way?
- You did not explain is not with threads, if you want to screw thread, cut threaded joint is broken, then a good joint,
Our company has integrated equipment and processing capacities of machining, heat-treatment, surface treatment, and hot extruding.
