Q:What are the installation requirements of the card sleeve joint?
The ends of the pipe shall be flush. The pipe should be flush in sawing grinding wheel and other tools, and burr cleaning and high pressure air blowing after use.When installing, the coaxiality of pipe and joint body should be kept as far as possible. If the pipe deflection is too large, it will cause sealing failure.The pre assembly force should not be too large. The inner blade of the clamping sleeve is just inserted into the outer wall of the pipe, and the clamping sleeve should not be deformed obviously. When the pipeline connection, and then according to the specified tightening force assembly. The tightening force of the phi 6-10mm card sleeve is 64-115N, Phi 16mmr 259N, Phi 18mm is 450N. If the sleeve is badly deformed at pre assembly, it will lose its sealing effect.(2) prohibit adding sealant and other fillers. In order to obtain better sealing effect, the sealant is coated with sealant, and the sealant is poured into the hydraulic system, causing the hydraulic components, such as damping holes, blocked and so on.(3) when connecting the pipe, the pipe should have enough deformation allowance to avoid the tensile stress of the pipe.(4) when connecting the pipeline, it should be avoided to be subjected to lateral force; the lateral force will cause the seal to be too lax.
Q:What do you mean by pipe fittings 3/4?
Supplement:1 inches =25.4 mm, =8 British points, 1/2 is four points (4 British points), DN diameter 15mm, 3/4 is six points (6 points), DN20mm.
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:Do you have DN150-DN80 variable diameter steel pipe joint?
Such components generally belong to standard parts, which is a national standard. It's easy to procure in the market.See details: "GB/T 12459-2005 steel welded seamless pipe fittings"The L length of DN150-DN80 is 140mm, and is H in the national standardSee below:
Q:What is a reinforced pipe joint?
The 200 in the DN80X200 of the pipe joint represents the thickness of the pipe wallPlease accept the answer and support me.
Q:How are the sleeve couplings joined?
The clamping ring is inserted into the outer wall of the steel tube by the action of the nut and the main body so as to form a seal
Q:The difference between expanding, clamping sleeve and welding pipe joint
Flaredfitting: flaredfitting medium: oil, water, gas and other non corrosive or corrosive medium 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, chemical industry, light industry, textile, metallurgy, national defense, aviation, shipbuilding and other systems; also suitable for hydraulic transmission of various mechanical engineering, machine tools and other equipment pipeline.
Q:The hydraulic pipe fittings how to distinguish the British, American, metric!
Also known as the metric metric tube thread pipe thread, 6810 diameter (pitch diameter of 12141618202224 (1); 1.5; 2730333639424548525660 (pitch) diameter pitch 2), divided into cylindrical and tapered pipe thread pipe thread, with the way into the column, cone and cone, cone two.
Q:The union bonnet (Union Bonnet) and bolted bonnet valves (Bolted Bonnet) the same?
There is no bonnet flange that is threaded directly.
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.
