Q:PVC how to deal with leaking water in the upper opening of three pipe joint of launching pipe?
And then find a PVC or half or more than half pipe cut off, the segments cut using UPVC glue in crack (crack, wrap) dry, you can prevent Water Leakage, but the specific will leak, will see you trap technology.
Q:What does flaring pipe joint mean?
To match the cone of the joint, although the processing is troublesome, the sealing is reliable. In addition, the use of copper tubes in general, the expansion is relatively easy.
Q:20ppr pipe joint is not what brand, 20ppr pipes can weld?
Standard requirement is to carry on the water and electricity warm transformation, is the water pipe and the joint choice same brand product.
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:Press the hydraulic pipe fittings standard need to do what procedures
Be sure to grasp the reasonable degree of withholding, with joint core hole shrinkage degree as the standard, GB joints under compression compression joints under ordinary small 0.1~0.4mm, small 0.1~2mm. Because the hose and the joint coat of different manufacturers, such as the GB standard for most northern rubber hose production plant, 602 standard for the south, foreign SAE standard, the factory hose, joint specific size, material may not be the same, so the buckling parameter table data for reference only, the specific size should be withheld according to the experimental pressure.
Q:Reinforced pipe joint,Used in chemical pipes
DN means the inner diameter, 25 is 25mm, and DN25 is "25 mm in diameter", length 300mm.
Q:The difference between expanding, clamping sleeve and welding pipe joint
Welded pipe joints: welded pipe joint applicable medium: oil, water, gas and other non corrosive or corrosive medium. The welding type sealing pipe joint with steel pipe specifications and flexible pipe welding, has the characteristics of reliable connection, good sealing performance, so it is widely used in oil refining and chemical engineering light industry, textile, metallurgy, aviation, defense, and ship system; also suitable for hydraulic transmission of various mechanical engineering, machine tools and other equipment pipeline. When the sleeve type pipe joint production can not meet the needs, and in the case of strong corrosion, priority can be adopted.
Q:What's the difference between pipe repair device and clamp type flexible pipe joint?
Generally applicable range is less than 16 kilograms, can not solve the limit problem, limited position can not solve the problem of flexible axial compensation.
Q:What is a slot type mechanical joint?Copy search
The groove type mechanical joint is a kind of pipe connection method that was developed in 1997. It can speed up the construction more than 10 times, and the reliability has reached the perfect level. Now, the fire fighting system has been adopted in this way. The rolling machine with the steel pipe processing a groove, and then the special clamp sealing ring will steel pipe and pipe fittings or two steel pipes are connected, convenient, and does not damage the galvanized layer, promotion of high,
Q:Standard Specification for jacket type pipe couplings for card sleeve couplings
Britain said the outer diameter and thickness of MM 10 1/4 10 "" 1/4 "" 1/2 12 "12.76 * 1.6012 (13) 3/8" "3/8 12" 17 * 2.25 "3/8 15" 15.87 * 1.6015 (16) 1/2 "" 1/2 15 "21.25 * 2.75" 20 3/4 19.05 "x 1.6020" (19) 3/4 "20 3/4 26.75" x 2.75 "251" 25.40 x 1.80251 ""
