Q:Is the pipe seat a pipe joint or a standard connection?
The branch pipe seat for reinforcing pipe type pipe connection, instead of the traditional use of different diameter three, reinforcing plate, strengthening pipe etc. branch connection type, which has the advantages of safety, lower cost, simple construction, improve the media channel, series of standardization, has the advantages of convenient use,
Q:Joint type of pipe joint
G is the pipe thread collectively (Guan), 55, 60 degrees division is functional, commonly known as tube round. The thread is machined from a cylindrical surface.ZG is a commonly known as cone, cone thread processing, pipe joint is generally the domestic old standard thread marked Rc thread RMetric threads are represented by pitch, and American and British threads are expressed in thread per inch. This is their greatest difference,Metric thread is 60 degrees equilateral tooth type, thread is isosceles tooth type thread 55 degrees, 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:Stainless steel pipe, wire joint leakage how to make up?
1) want to save trouble, buy special glue to block, general hardware store can buy;2) the silk joint opens, the more winding some raw rubber tape, then turns tight to see whether can solve the problem;3) if it is a silk joint, replace the wire joint;4) the pipe is re tapped or replaced with a new pipe;
Q:Do you have DN150-DN80 variable diameter steel pipe joint?
Do you have DN150-DN80 variable diameter steel pipe joint? Is there a standard in this respect?What's his length, L? Look at the picture
Q:Classification of pipe couplings for hydraulic couplings
Hydraulic hose, high pressure ball valve, quick joint with odd intention and sleeve type pipe joint
Q:What are the specifications and models of hydraulic pipe fittings?
The connection forms of the pipe joint include thread, welding and clamping sleeve, and the shape of the pipe joint is straight through and elbow
Q:Can the pressure vessel pipe joint adopt G thread? Why?
1 、 pressure vessel pipe joints do not use G thread, because G thread is not sealed enough.
Q:Can the pneumatic pipe connection be carried through the water?
There are two types of pneumatic couplings, the quick couplings are not available, and the other can be inserted into the pipe and locked outside with the nut
Q:G1/8 "pipe joint end special sealing WD-B02 is what mean
The special sealing ring WD-B02 for the end of pipe joint is one of many industrial seals. It is used as a special seal for hydraulic fittings such as pipe joint, hydraulic plug and transition joint,
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
