Q:Hydraulic tubing connections are made of material steel
Hydraulic tubing connections are generally over 20MPa to 40MPa, high pressure multi carbon steel and high strength steel, low pressure useful carbon steel, red copper or brass material
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 joint seal, with raw meal belt and sealant that good?
It is best not to use, with American conical teeth hard seal, NPTF generally very few people with this. High precision ah!
Q:Screw in pipe joint Dg10 what do you mean?
For example: the nominal diameter of 100MM seamless steel pipe 102*5, 108*5 several, 108 for the outer diameter of pipes, 5 said that the wall thickness of the tube, therefore, the pipe diameter (108-5-5 = 98MM), but it is not completely equal to two times the wall thickness of the pipe diameter difference, it can be said that the public said the diameter is close to the diameter, but not equal to the diameter of a pipe diameter specifications on the design drawings, so we use the nominal diameter, the purpose is to determine according to the nominal diameter pipe, flange, gasket structure dimensions and connection dimensions, nominal diameter is represented by the symbol DN, if the diameter of in the design drawings, piping specifications should also make the table, show that the nominal diameter of a pipe wall thickness.
Q:What are the types of tubing and pipe couplings?
According to connection tubing and pipe joints, pipe joints are welded, sleeve type, expanding type, press type form; each form of pipe joint,
Q:Air conditioning outdoor units, pipe joints, frosting, or even icing
If it has been opened to the maximum opening, the cooling effect is still not good, and here frost and ice, should consider replacing filters, after washing the pipeline, re vacuum and refrigerant.
Q:What is a slot type mechanical joint?Copy search
Because of the special sealing structure design of the rubber sealing ring and the clamp hoop, the groove connecting piece has good sealing property, and the sealing property is enhanced correspondingly with the increase of the fluid pressure in the pipe.
Q:Hydraulic hose connector size 20As shown in Figure six, the angle is 71mm to the edge, 80mm to the diagonal, approximately 34mm higher
Hydraulic joint standardHydraulic pipe fittings - thread standard twoClassification of threadsThe 1. threaded internal and external threads two;2. according to the shape of teeth can be divided into: 1) triangular thread 2) trapezoidal thread 3) rectangular thread 4) sawtooth thread;3. by line, single, head and multi thread;4., according to the direction of rotation, two kinds of left and right threads, the right is not marked, left plus LH, such as M24 * 1.5LH;5. according to different uses are: metric common thread, thread sealed pipe thread, non threaded sealing pipe thread, 60 degrees taper pipe thread, metric taper thread, etc.

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
