- Q:Will the moving angle of the air conditioner indoor be harmful to the connecting pipe joint?
- There's nothing wrong with the moving angle. Our unit air conditioning because moving, we have been disassembled and assembled several times (copper tubes are disk, installation and then stroke straight), there is no leakage problems.
- Q:What are the standard drawing numbers for hydraulic couplings?
- (two) prohibit adding sealant and other fillers. Some people in order to obtain better sealing effect, in the card cover with sealant, the result of sealant is poured into the hydraulic system, causing hydraulic components, such as plugging holes.(three) when connecting the pipe, the pipe should have enough deformation allowance to avoid drawing the tube.(four) when connecting the pipeline, the lateral force should be avoided, and the lateral force will cause the seal to be too tight.(five) when connecting pipelines, should be a one-time good, avoid repeated disassembly, otherwise it will make poor sealing performance.
- Q:What's the half pipe connection?
- The half pipe connection essentially means that the branch pipe becomes larger when it is connected to the main pipe through the half pipe joint
- Q:What are the types of hydraulic couplings?
- Is a flat +O ring, C - like Japan, spherical ring - free, H - like Germany, 24 degrees cone +O - shaped ring.Each has hundreds of models, depending on the manuals and samples.
- Q:What is pressing type pipe joint
- If necessary, I will send you the connector type and specifications
- Q:Man, can you send me some national standards? Mainly for hydraulic use
- Domestic standards, I do not have any standards, the domestic standards of learning German, learn from other countries standards, do very badly.SN standard pipe taper angle of 24 degrees and 30 degrees in China, can not mix.
- Q:Will that be all right? Then there's the PPR pipe joint on the right. Is that ok?
- You don't see this picture very clearly. You mean there's a lot of right side connections, right?
- Q:Drawing design, drain cross dry pipe is flexible cast iron pipe, vertical pipe is PVC pipe joint
- But in actual construction, because the special AD type bottom joint is more expensive, the construction unit usually adopts the cast iron pipe elbow to deal with the problem of reducing the diameter of the two kinds of materials.
- Q:What are the types of tubing and pipe couplings?
- According to the number and direction of the connection, there are straight through, right angle, three pass and other types; the connection with the body has threaded connection, flange connection and so on. In addition, there are some special purpose pipe couplings.
- 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.
Our company has integrated equipment and processing capacities of machining, heat-treatment, surface treatment, and hot extruding. For human resources, we have 16 senior engineers, 16 engineers and technicians and 14 inspectors, and have advanced processing technology and experience in casing and tubing couplings, pup joints, tool joints and down hole tools. Quality of our products is stable and excellent.
