- Q:Very confused about the pipe fittings and the fittings, and can not distinguish them
- Pipe jointIt is a joint on a hard tube or hose, and it must be installed at the end of the pipe to connect it to the fittings or the equipment
- Q:How to compile the welding technology of 12CrlMoVG header and pipe joint
- 1 welding method argon arc welding wire H08CrMoG.2, process:(1) welding example, economizer, evaporator section, tube bundle, water wall and low temperature superheater are made of No. 20 steel, and high temperature superheater tube is 12Cr1MoV.
- Q:Inside and outside the threaded joint, one end of the internal thread (G),
- The cylindrical internal thread and the taper outer thread form a column / cone fit; the taper internal thread and the taper outer thread form the cone / cone matching.
- Q:Auto air conditioning condenser and high pressure pipe joint leakage, can use sealant?
- No, it must be treated fundamentally, welded pipe or change the sealing ring
- Q:What are the types of tubing and pipe couplings applicable to each occasion?
- Pipe joint is detachable between the tubing and tubing, tubing and hydraulic components of the connection, it should satisfy the convenient assembly and disassembly, reliable connection, reliable sealing, small size, large capacity oil, small pressure loss, good processing etc.. According to connection tubing and pipe joints, pipe joints are welded, sleeve type, expanding type, press type form; pipe joints each form, according to the channel number and direction of joint points straight, rectangular, three other types; threaded connection and flange connection with the connection of the body. In addition, there are some special purpose pipe couplings.
- Q:What is the reason that the rubber hose of the fire hose is flowing black oil?
- This is the groove of the fire trench, the connection of the pipeline meets all the requirements and the quality is not satisfied. That is, the quality of aprons.
- Q:How many types of hydraulic connections?
- The difference between hydraulic pipe joint and common pipe joint:The biggest and most significant difference is that the hydraulic pressure is large, amazing, the hydraulic tubing suddenly burst, the impact of oil is very large.Cannot use the ordinary replacement special-purpose joint, because the hydraulic pressure all can withstand the very big pressure, the ordinary 0.5 most barometric pressure already nearly died.
- 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:Hydraulic hose joint is spherical and cone sealing, threaded connection, what is the form of joint?
- UNF often used to transport water (high temperature), the imperial teeth often used to transport oil (high pressure).
- Q:The gas cooker joint is pagoda shaped. Can it fall down and connect with bellows joint directly?
- The provisions of China's domestic gas (gas interface with connection terminal interface), must be 55 degree cylindrical internal thread sealing pipe thread and external tapered thread sealing pipe thread, 55 degree conical internal thread and external tapered thread, 55 degrees of one of three non sealing pipe thread.A bellows is a tubular elastic device that is joined by folding wrinkles along a folded and telescopic direction. Bellows joints for civil water pipes and gas appliances are mostly 55 degree non hermetic pipe threads.Because the form of pipe joints is very large, they can be used in conjunction with the same thread and sealing form, so it is not sure whether the joint of the pagoda can be dropped or not.
