Q:What are the reducing, reducing, reducing, etc in the pipe joint?
Do not know where you see these pipe joint nouns, you should say are all variable diameter pipe joints.
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:PVC can the pipe joint be butted with the joint? How do I get it?
For example: 110mm diameter PVC pipe joint two, to connect them, you can cut a 110PVC tube (length 8cm), at the end of a first pipe with special glue inserted into a connector, then put another head on glue, then inserted into another joint, so ok.
Q:Hydraulic jointWho knows the hydraulic connection "3/8*25.4=9.525" refers to the connection?
The ends of the pipe shall be flush. The pipe should be flush in sawing grinding wheel and other tools, and burr cleaning and blowing with high pressure air before use. When installing, the coaxiality of pipe and joint body should be kept as far as possible. If the pipe deflection is too large, it will cause sealing failure. If the pre loading force is unfavorable, the inner edge of the ambassador card sleeve is just inserted into the outer wall of the pipe, and the clamping sleeve should not be deformed obviously. When the pipeline connection, and then according to the specified tightening force assembly. Phi 6-1 card sleeve tightening force is 64-1 15N, 16 MMR 259n, Phi Phi 18mm for 450n. If the sleeve is badly deformed at pre assembly, it will lose its sealing effect
Q:Reinforced pipe joint,Used in chemical pipes
20# steel, JB 4726-2000 material "pressure vessel with carbon steel and low alloy" standard, SW socket welding.  40T025/01 is drawing number, SCH80 diameter specifications. See below;
Q:How to identify the pipe joint thread quickly and accurately?
1 use a thread gauge to check the gauge of the pipe joint, which is the most accurate.2, you can also use special tools, taps (for female pipe joints) and wrench (for pipe fittings), which is a tool for making pipe joints. Try it on and see if it's easy to screw in. If it is easy to screw in, you can determine the specifications of the unknown pipe thread according to the specifications of the known taps and wrench marks.
Q:The difference between expanding, clamping sleeve and welding pipe joint
Sleeve type pipe joint: the working principle of the clamp sleeve is to insert the steel tube into the clamp sleeve, lock the sleeve with the nut, contradict the sleeve and cut into the pipe to seal. The utility model does not need welding when connected with the steel pipe, and is favorable for fire prevention, explosion prevention and high-altitude operation, and can eliminate the defects caused by careless welding. Therefore, it is a kind of advanced connecting device in pipeline, automatic control device, pipeline, oil refining, chemical, petroleum, natural gas, food, pharmacy, instrument and meter, etc.. Apply to oil, gas, water and other medium pipeline connection. The card connector has reliable, high voltage capability, high temperature resistance, good sealing and repeatability, installation and convenient maintenance, safe and reliable connection.
Q:Hydraulic hose joint is spherical and cone sealing, threaded connection, what is the form of joint?
WREN we also do ultra high pressure joint (hydraulic joint) and all hydraulic wrenches, hydraulic pumps, etc., you can contact us to negotiate!
Q:How to choose the connection mode of clamp type flexible pipe joint correctly
Pipe end connections do not need to be done to the end of the pipeThe pipe end connection omits the overall length of the pipe and reduces the costThe overall price of the clamp joint at the end of the pipe is higher than that of the steel ringThe steel ring adopts the way of socket welding, and has certain requirements for the welding positionThe steel ring requires cleaning of the pipe port, i.e., the sealing surface
Q:Puvc pipe joint leakage how to do?
Changing a new one is cheaper than maintaining it. If your part doesn't allow you to change it
