- Q:Is the pipe seat a pipe joint or a standard connection?
- It is used more and more widely, especially in high pressure, high temperature, large diameter and thick wall pipes. It replaces the traditional method of branch pipe connection. The main body of the branch pipe is made of high quality forgings. The material is the same as the pipe material. Carbon steel, alloy steel, stainless steel and so on. The branch pipe and the head adopts a welding, pipe seat and branch pipe or other pipe (such as tube plug, etc.), instruments and valves connected with butt welding, socket welding, threaded types.
- 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:Man, can you send me some national standards? Mainly for hydraulic use
- Here you are, some European companies, but you need to download them on the Baidu Library
- 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:Maintenance skills of fire hose clamp joint leakage
- A fuse is generally used when Water Leakage threaded connection, trench connection pipe to check whether the sealing surface is flat and smooth, without burr. Whether the sealing surface of the sealing ring is scratched and whether the length of the sealing section meets the requirement. These are three guarantees. They won't leak.
- Q:What are the links between hydraulic components and pipe couplings that are used to prevent leakage?
- If it is a cylindrical thread, depending on the pressure, you can use a combination washer, copper gasket, O Ring + ring, rectangular ring and so on
- Q:The expansion type pipe joint and the sleeve type pipe joint difference, everybody looks at the picture, this is belongs to that kind of?
- The material of the pipe has a problem, it is a hose. So what kind of form do you have?. If the straitjacket of words, should belong to flaredfitting.
- Q:Why are the sleeve joint leaks?
- Main reasons and troubleshooting methods of oil leakage in sleeve type pipe joint:The card sleeve type pipe joint with highest accuracy requirements (diameter > drawn tube. When the cold drawn pipe and the sleeve matching parts are not closed, the strain has an axial pin (the outer diameter of the pipe and the inner diameter of the sleeve), it will leak. Solution: at this time can be cut off a strain of cold drawing tube, or replace the card re assembly qualified.
- Q:Hot melt pipe joint leakage how to do?
- 2, dry leakage parts, with Wang Yu (waterproof cement) to buy. Less water, very thick situation, large surface paste in the water leakage position. This method is also used to remedy cast iron pipes.
- 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
