Q:How do you explain the pipe joint?
Steel pipe marking should be DN, DN is nominal diameter, DN20 galvanized pipe does not mean that the outer diameter of the pipe is 20mm, the outer diameter of the steel pipe, but 26.8mm; DN15 galvanized pipe, the outer diameter is 21.3mm.
Q:What is the manual pre assembly procedure for the EO-2 joint?
I. pre assembled1, EMB card sleeve type pipe joint pre assembly of the most important link, directly affect the sealing reliability. A dedicated preprocessor is usually required. The small diameter can be pre joint in a vise. The concrete method is to use a joint as the mother's body and press the nut and the sleeve onto the tube. The utility model mainly comprises a sleeve type through pipe joint, a clamping sleeve type end through connection head, a clamping sleeve type three way pipe joint and other patterns. I found that even if the same manufacturer of a batch of goods, the cone of these joints on the depth of the hole is often different, resulting in a leak, and this problem is often neglected. The correct approach is to connect the end of the pipe with what kind of joint, and the corresponding connection ends are prefabricated with the same type of joint, so that the leakage problem can be avoided to the maximum extent.
Q:Hydraulic pipe fittings, DIN, GB, American Standard how to distinguish?
ZG is a commonly known as cone, cone thread processing, pipe joint is generally the old GB marked Rc for metric threads to represent the thread pitch, with every inch of the thread number, this is the biggest difference between them, metric thread is 60 degrees equilateral tooth type. 55 inch thread is isosceles tooth type of thread, 60 degrees. Metric units for metric threads; British and American systems. Pipe thread is mainly used for pipe connection, the internal and external threads are closely matched with straight pipe and cone pipe two kinds. Nominal diameter refers to the diameter of the pipe to be connected. Obviously, the diameter of the thread is larger than the nominal diameter. 1/4, 1/2, 1/8 is the nominal diameter of inch inch, inch in inches.
Q:Apart from the air-conditioning, the high-pressure pipe is not tight enough. What shall I do?
Will affect the cooling effect, it is recommended to cut off the connector, and then use reaming device to expand after re installation. Charges will not be too high, dozens of blocks enough to be careful to be pit.
Q:G1/8 "pipe joint end special sealing WD-B02 is what mean
WD circle of different names is divided into: ED ring, ED ring, hydraulic pipe joints, pipe joint gasket seals and so on, the use of pressure: 5 (MPa), the use of temperature: 200 (c), properties: corrosion resistance, high temperature resistance, abrasion resistance, applicable scope: pump, cylinder, sealing, effect material: nitrile rubber (NBR) fluorine rubber (VITON).
Q:What's the meaning of the pipe joint 14-M18*1.5? What's the thickness of the wall?
The assembly of the sleeve type pipe joint (1) the most important part of the pre assembly of the sleeve type pipe joint directly affects the reliability of the seal. A dedicated preprocessor is usually required. The small diameter can be pre joint in a vise. The concrete method is to use a joint as the mother's body and press the nut and the sleeve onto the tube. The utility model mainly comprises a sleeve type through pipe joint, a clamping sleeve type end through connection head, a clamping sleeve type three way pipe joint and other patterns.
Q:How to choose the connection mode of clamp type flexible pipe joint correctly
The overall price of steel ring is lower than that of pipe endSummary: the middle and high pressure pipeline is recommended to use the pipe end connection, and the middle and low pressure pipeline is recommended to use the steel ring connectionThe customer can choose the clamp type flexible pipe joint (steel ring joint) or clamp flexible pipe joint (pipe end connection) according to the demand to reduce the purchasing cost.
Q:The material is 304 stainless steel 1/4 "NPT" threaded joint. How much MPa pressure can be received?
As the master of the world pipe joint wellock, stainless steel NPT thread pressure they can do 200-760BAR, and different pressure according to different sizes
Q:Puvc pipe joint leakage how to do?
That will help you do better plugging without changing the new foundation. But the cost is several times higher than the new one. Ha-ha
Q:Outside the wire (wire) of what the standard joint size
Structure and characteristics:The utility model relates to a sleeve type metal hose joint, which can connect a steel pipe without a thread and a hose, and can save the thread filling process, and only screws can be screwed in;The metal fittings are jacketed to connect the metal hose to the non threaded steel tube;Adaptation: steel thin steel wire pipe, black, tin pipe (water, gas);When choosing the ferrule type metal joint, please pay attention to the specification and size of the connecting pipe hose.Installation notesIn our daily life, we often see the pipe fittings on the pipe fittings. For this kind of products, we need effective installation to ensure that it can perform its functions better. Here is a brief discussion of a kind of pipe joint - card sleeve type joints in the installation of the use of methods.
