Q:How to compile the welding technology of 12CrlMoVG header and pipe joint
(2) before welding, before welding, the pipe should be 30 degrees, and the inside and outside 15mm range of the pipe should be polished to be metallic. The pipe clearance is 1~3mm. When the actual clearance is too large, the transition layer shall be deposited on the side of the pipe groove. Set up temporary shelter facilities, strictly control the wind speed at the welding operation place, and the air hole is easy to generate because the wind speed is beyond a certain range.(3) the operation uses WST315 manual tungsten argon arc welding machine, the welder itself is equipped with high frequency arc striking device, and the high frequency arc striking can be adopted. The arc and arc electrode, such as arc too fast, easy to produce crater crack, so the operation will lead to the edge of the pool or parent material is thick, and then gradually reduced the pool slowly extinguish arc, and finally close the protective gas.
Q:What is the difference between the pipe and the pipe joint?
Two, plastic pipe type 1, PVC (PVC-U) plastic wire pipe (hard tube), 2 and PE threading pipe (winding hose) 3, plastic bellows (flame retardant bellows, wire harness casing, high density bellows, high temperature protective casing, etc.)
Q:Inside and outside the threaded joint, one end of the internal thread (G),
Generally speaking, pipe threads refer to British pipe threads. There are two ways of matching the thread of an inch sealing pipe
Q:May I ask what material EN39 is? Used to make a threaded pipe joint
EN39 is a European standard, the standard number is EN39:2001. The standard formal name is: carbon steel pipe for scaffolding.
Q:Hydraulic pipe quick coupling principle of hydraulic pipe joint
JB/T6381 ~ 6385-1992 burking hose connector has the advantages of convenient installation, but added a tightening process. After the hose is damaged, the joint coat can not be reused, and it is made up of a steel wire braided hose. The utility model can be connected with a welding pipe joint sealed with a O ring. Pipeline system suitable for oil, water and gas as medium. Medium temperature: Oil: -30 ~ 80 degrees Celsius; air, -30 ~ 50 degrees Celsius; water, 80 degrees below JB/ZQ4427 ~ 4428-1986, three valve type hose joint assembly, do not need to remove the rubber tube of the outer layer. A slightly different diameter of hose hose, hose on the joint coat of pre compression to compensate. Hose pre compression in 31% ~ 50% range to ensure no leakage under the pressure of work, will not pull glue, cover does not break. With the welded pipe joint, quick joint, sleeve type pipe joint used for oil, water and gas pipeline system for medium, working pressure, medium temperature by connecting hose limited JB/ZQ4429 ~ 4431-1986 quick change connector (both open and closed) tube apart and self sealing pipe. In the liquid will not be lost, so it is suitable for frequent disassembly occasions. The structure is complex, and the local resistance loss is greater. Suitable for oil and gas pipeline system for medium, the working pressure is lower than 31.5MPa, the medium temperature of -20 to 80 DEG JB/ZQ4434-1986 quick change connector (both ends open) for oil and gas pipeline system for medium, the working pressure of medium temperature according to connecting hose limited JB/ZQ4435-1986
Q:Is the thread at the two ends of the card sleeve the same?
InequableThe card sleeve is divided into two types: a single card sleeve and a double clamp sleeveThe sleeve end thread single card is generally metric thread, 6mm or 1/4 "card sleeve thread is M12*1.5."G1/4 is pipe thread with fixed thread, outer diameter and pitchDouble card for UNF fine thread (also have metric teeth, but already very little), and G1/4 internal thread is even more not matching
Q:How to choose the connection mode of clamp type flexible pipe joint correctly
The overall price of steel ring is lower than that of pipe endSummary: the middle and high pressure pipeline is recommended to use the pipe end connection, and the middle and low pressure pipeline is recommended to use the steel ring connectionThe customer can choose the clamp type flexible pipe joint (steel ring joint) or clamp flexible pipe joint (pipe end connection) according to the demand to reduce the purchasing cost.
Q:Connect with stainless steel tube with 304 stainless steel clip type pipe joint,
In the process of using, as a general instrument to take pressure, the general gas and liquid pipelines, 10 kilograms are no problem. We usually use 10 kilograms of steam piping instrument to take pressure, no problem.
Q:The pipe connections have different diameters. Reducing the diameter, what else?,
According to the form of joints: pipe plug, two - way connector, three - way connector, four - way connector,
Q:PVC pipe joint leakage how to do?
3. if it is a faucet, it is caused by the abrasion of the core gasket in the faucet. Use pliers to pull the gland loose and remove. Remove the axle washer with a clamp and change it with a new axle washer.
Our main products are double eccentric metal/rubber seated butterfly valves, triple offset butterfly valves, tilting disc check valves, centerline butterfly valves, ebonite butterfly valves, eccentric plug/ball valves, gate valves, globes and power station valves, with sizes ranging from DN40mm (2") to DN4000mm (160") and PN ranging from 0.01MPa to 6.4MPa.
