Q:What are the reducing, reducing, reducing, etc in the pipe joint?
The pipe joint is divided into cylindrical pipe thread and tapered pipe thread, and the change of diameter refers to the different diameters of the two ends of the pipe joint
Q:How do you explain the pipe joint?
The fittings are expressed in part according to the British system
Q:Stainless steel pipe, wire joint leakage how to make up?
What is the pressure in the pipe? The glue material is not blocked up, in the humid environment and water under the condition that the glue is not stick, reliable and economic way: cold metal flux were patching, simple and convenient, do not need what tools
Q:Auto air conditioning condenser and high pressure pipe joint leakage, can use sealant?
Should replace the high-pressure pipe or tube sealing ring in order to solve the problem.
Q:Requirements for fire hose fittings
(2) galvanized steel pipe with diameter > 100mm of hydrant water supply system shall be flanged or grooved. The automatic sprinkler system, 100mm diameter is not clear thread connection cannot be used in pipe diameter greater than 100mm shall be provided with flange connection or groove connection point at a distance only.(3) the water supply system of fire hydrant water supply system and automatic sprinkler system shall be threaded flange, and two zinc plating shall be adopted when welding flange is adopted.
Q:Specification for thread of gas couplings
5, pneumatic joints of different series used in different places, specific size can find these brands of websites, generally all brands have their own web site, the website has relevant dimensions description.6, if not clear enough, you can find these brands in Baidu, and then call them to obtain product catalogs, so that more clear.
Q:What is the size of the PVC pipe joint?
In practical applications, stabilizers must be added to improve the stability of the heat and light. PVC is very hard and can only be dissolved in a few solvents such as cyclohexanone, two dichloroethane and tetrahydrofuran. It is stable for organic and inorganic acids, alkalis and salts, and the chemical stability decreases with the increase of the use temperature.
Q:Can the pressure vessel pipe joint adopt G thread? Why?
Can not. G threads are not sealed enough.The following three threads can be used.1.55 degrees taper external thread R and cylindrical external thread Rp matching2.55 degrees taper external thread R and taper external thread Rc fit3.60 degrees taper internal and external thread fit PT.Glass can not be sealed only by thread.
Q:Hot melt pipe joint leakage how to do?
First of all, to find the cause of leakage of hot melt pipe joints, there is a reason to know how to answer, the following are a few solutions;1, the safest solution is to replace the leaking parts of the pipe. Off valve, drain, with PPR scissors cut Water Leakage parts of pipeline, PPR soup machine, with a direct it. The process is uncomplicated and the skilled worker will be able to solve it in 30 minutes.
Q:PPR pipe joints did not plug in the melt, in the end will leak?
1, pipe and pipe fittings should be adopted hot melt essentials, not allowed in the pipe and pipe fittings directly to the wire, and metal pipe can flange connection, and with water device connection, must use metal insert pipe fittings;2, the construction of hot melt connection must use the quality of reliable hot-melt equipment to ensure the quality of welding;3, the use of special scissors cutting vertical pipe shall be smooth without burr, argot;4, clean welding pipe fittings, the quality of sand, dust and other restraint damage are discussed; and the heating head is welding material inherited size related firmly in the hot melt machine, connected to the power supply, heating temperature to reach the best looking head;
