Q:What is the difference between a D-LD2000 clamp type flexible pipe joint and a KRJ clamp flexible pipe joint?
Four, flexible pipe joint internal structure and KRJ internal structure is slightly different, flexible pipe joint no retreat or small platform, and the latter is large return platformFive, flexible pipe joints, standard clamp type flexible pipe joints, disassembly can be worn down, shoulder type flexible pipe joints can not be.Note: some units in the market now confuse the two products with the aim of selling high priced products at lower prices so that they can make more profit margins. To ask for the data parameters of the drawing, to judge whether it is a flexible pipe joint or a flexible pipe joint.
Q:How tight is the gas pipe joint?
The gas pipe joint for plastic pipe and metal pipe joint connected with hose clamps, locking can achieve the sealing connection.
Q:What are the types of tubing and pipe couplings?
Pipe joint is detachable between the tubing and tubing, tubing and hydraulic components of the connection, it should satisfy the convenient assembly and disassembly, reliable connection, reliable sealing, small size, large capacity oil, small pressure loss, good processing etc..
Q:About thread, pipe joint standard question
The world's three major thread standards, individuals feel very good, although six or seven years of work
Q:Air conditioning outdoor units, pipe joints, frosting, or even icing
As long as the counterclockwise rotation, with the starting force of about 10% of the screw can not move, it means that it has been opened to the maximum degree.
Q:How much is the monofilament of the 304 pipe joint?
Small size is cheaper, and one more thing is the thread standard you want to connect to
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:Hydraulic hose joint is spherical and cone sealing, threaded connection, what is the form of joint?
UNF often used to transport water (high temperature), the imperial teeth often used to transport oil (high pressure).
Q:The union bonnet (Union Bonnet) and bolted bonnet valves (Bolted Bonnet) the same?
And plug valve bonnet (bolted): there is a valve cover flange, the valve cover flange is bolted and connected to the valve body, and then stuffing box.
Q:PPR pipe joints did not plug in the melt, in the end will leak?
A, in general, as long as the PPR hot melt pipe effective connection, through the fusion will fuse together, will not leak, and if not assured, it is recommended to re melt.Two, the pipeline before welding to seriously clean pipes and appearance, cleaning pipe appearance of oil, impurities and burrs. To carefully insert pipe length should be appropriate, should be symmetrical flange to discuss the formation of pipeline connection, if not well proportioned, stability that side, reflected weld is not ideal, the discussion is not difficult to guarantee Water Leakage, you should promptly reconnect.
