- Q:Outside the wire (wire) of what the standard joint size
- The metal joint is made of zinc alloy. The surface is zinc plated, sanded or chrome plated. The structure is close, without porosity and high strength. Reliable connection with metal hose, beautiful appearance;The metal joint is an end connection and a linear connection for connecting the metal hose to the case;It is recommended to use an inch metal hose joint or a metric thread metal joint;Can be customized a variety of non-standard metal hose joints, special metal joints.Ferrule type metal joint
- Q:What's the half pipe connection?
- The main function is to connect the small main pipe to the big main pipe and reinforce it. The common branch pipe is smaller than DN50, will use half pipe joint, more than DN50, must choose the variable diameter three links to connect.
- Q:How about the water pipe fittings and millimeters?20mm is 425mm is 6Why
- This is the confusion caused by the confusion of the three conceptsA,4 points, is commonly known as, should be 1/2 inches,.4/8 is 4 copies6 points, 3/4 inches,.6/8 is 6 copies
- Q:Principle of fast pipe joint
- The application with a one-way valve, a one-way valve end is connected with the gas source, when the check valve closes automatically when connected to a one-way valve open end of the thimble.Self locking is the use of steel balls embedded in the groove, while the "cone - cylinder" sleeve to lock the ball.
- Q:How to use the clamp type pipe joint?
- The clamping sleeve type straight through joint has clamps at both ends, and it is worn at the end of the pipe which needs to be connected, and then it is clamped and connected with the nut,
- Q:PT1/4 large diameter pipe joint? No figure urgently
- The thread has a taper of 1:16, equivalent to 55 degrees taper pipe thread, or ZG
- Q:What is the taper angle of flared tubular joints?
- Expansion type pipe joint applicable medium: oil, water, gas and other non corrosive or corrosive medium pipe joints, with steel pipe specifications requirements more flexible, and pipe welding
- 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:Does the American and English fittings how to recognize it?
- Inch thread is an isosceles triangle with 55 degrees, 60 degrees is made of an equilateral triangle, if you have a good tooth type gauge measurement, also the same number of teeth have more teeth than American english. Therefore, the two threads in your subject are short in length and inch in english.
- Q:The hydraulic pipe fittings how to distinguish the British, American, metric!
- Metric thread tooth angle of 60 degrees, fine teeth; British American pipe thread pitch, basically the same, but the BSP screw tooth angle is 55 degrees, American pipe thread angle is 60 degrees. The difference between the metric and inch pipe screw thread, the:
