Q:Antistatic flame retardant PE plastic pipe installation, what should pay attention to?
When installing the pipe, the distance between the two socket flexible connections shall be no more than 3 meters. When the length compensation is needed, the pipe can be completely inserted into the socket and then out of the 10mm. Flexible connections between pipes and fittings can absorb thermal expansion of pipes up to 10mm.
Q:Plastic Yong connector temperature is too high, how to do? Can reflect the sound quality of PPR tube?
Hot melt machine regular manufacturers generally have red and green indicator light, red light green light is on behalf of heating, constant temperature, don't use it first reaching the green, must be used up to second green, hot melt temperature at 260 DEG -280 deg. Lower than or above the temperature, will cause the connection can not be fully fused, leaving water seepage hazard.
Q:How to connect the wire mesh, steel tape and plastic composite pipe?
The connection of hole net, steel belt and polyethylene composite pipe can be made in two ways: fused pipe fittings and flange joint.
Q:PE is the hot melt?
1. When using this method, the hot melt butt welding machine is adopted, and the main operation steps are as follows:After the butt welding machine has been debugged, put the pipe to be placed on the welding jig and clamp;The cleaning pipe end to be connected and connected with two end milling cutter alignment docking, the displacement is not greater than the pipe wall thickness of 10%:When the temperature of the heating plate reaches the set temperature, put it on the heating plate:After heating, take out the heating plate, quickly start the oil pump pressure, join the two pipe heating surface, and step up to the welding pressure, keep pressure and cool down:After cooling to the specified time, open the clamp and remove the pipe from the rack, observe the roll edge, determine the quality of the connection, and complete the connection.2. Check the quality of hot melt butt jointThe determination of the quality of hot melt butt welding is still mainly concerned with nondestructive appearance inspection of welding roll edges. Usually includes edge geometry and cutting edge visual inspection, the edge to behind the buckling to prove that connected with no lack of fusion check.Ultrasonic testing and X ray examination have been applied abroad.Destructive detection. Tensile test, bending test and tensile creep test are carried out at the interface respectively.3, hot melt docking notes:The procedures for the use of the docking machines and the matters needing attention shall be observed;Operators must wear gloves, wear overalls, do a good job of self-protection, to avoid electric shocks or burns;Heating the surface of the board, and the connecting ends should be kept clean:Docking pressure should be adjusted to the actual needs of the site:Polyethylene pipes shall not be heated by open flame;The welding interface to protect from sand and rain hit.
Q:Method for using steel wire mesh skeleton plastic composite pipe
Welding replacement of electric melting pipe fittings, must ensure that the pipeline without water retention, otherwise it is difficult to weld the fused pipe solid.
Q:What tools and methods are needed for the installation of plastic hoses and steel tubes?
(1) quantity. When the storey height is less than 4 m, the riser shall be provided with a telescopic joint on each floor; when the storey height is greater than 4 m, the design shall be determined according to the design expansion amount, and the maximum allowable amount of expansion shall not be greater than the expansion joint(2) site. The construction units often think that as long as the drainage pipe is provided with a telescopic section can satisfy the requirement, even as the expansion joint connecting pipe joints, Water Leakage caused by seepage, the correct approach is socket expansion joint should be set along the direction of flow, when the drainage pipes in the floor below access riser expansion joints should be set under water confluence pipe; when the drainage pipes in the floor above the access riser section should be arranged on the telescopic water confluence pipe; drainage pipes in the floor and upper and lower access, should be located in the middle section of the telescopic floor. At the same time, when the riser passes through the floor as a fixed support, the expansion joint can not be fixed, and when the contraction section is a fixed support, the riser can not be fixed through the floor. A telescopic joint arranged on the transverse pipe shall be arranged at the end of the water current converging pipe fitting.
Q:How is the building material, plastic pipe and sewer made? Where are the machines and how much is the selling price?
The raw materials for the general characteristics of production technology of pipe fittings and pipe the same general, China is now the popularization and application of plastic pipe of many varieties are: polyvinyl chloride (PVC) tube (in the form of the structure can be divided into: single tube solid wall pipe, reinforced radial pipe, core layer foam pipe, spiral pipe muffler double wall corrugated pipe, single wall corrugated pipe etc.), polyethylene (PE) pipe series products (according to the density and structure divided into HDPE, MDPE, LDPE double wall corrugated pipe, spiral wave fiber winding tube etc.) chloride PVC pipes, crosslinked polyethylene (PE-X) pipe, three type polypropylene (PP-R) pipe, polybutene (PB) pipe, ABS (three copolymer acrylonitrile butadiene styrene ethylene) (SP) pipe, aluminum-plastic composite pipe, high temperature resistant non crosslinked polyethylene (PE-RT), ultra high molecular weight polyethylene (UHMW-PE) pipe, polyethylene silicon core pipe and so on.
Q:How to connect the steel tube and the steel tubes?
The connection of wire mesh frame and plastic composite pipe is made up of two kinds of electric heating welding and flange connectionElectric melting connection is a composite pipe socket to electrofusion fittings, make embedded electric heat wire on the surface of the heating pipe. The pipe inner surface of melt generated melt, melt and fill the gap until the expansion pipe fittings, pipe appearance also produced two kinds of melt, melt each other together, cooling and forming after the pipe fittings are closely connected as a whole.
Q:How to set the quota for plastic pipe fittings?
Installation of plastic pipe installation, the plastic flange installation included in the quota items in the valve flange.
Q:What are the connecting modes of steel wire mesh and plastic composite pipes?
Characteristics of electric fusion welding:Electric heating welding technology is convenient for construction. Prompt. The connection installation group can be implemented, and the uniform welding can be carried out.The welding reliability is good and the strength and density are better than those of other connections.Keep the inner wall smooth, without affecting the flow area.
