Q:What are the common connecting methods for plastic PP pipes?
The electric wire welding method: the oxidation of the tube surface skin removed, insert pipe specifications corresponding with the electric heating element, the heating element to the rated current through a certain period of time, polypropylene pipe fittings and pipe joints to heat and melt each other, turn off the power, thus forming an inseparable interface. The butt welding of the pipe end treatment method: first, with the heating plate placed on well tube and tube or pipe and pipe fittings, set the heating temperature, close the control power, heating, pumping out the heating piece, and then ends by force rapid docking together to form a high cooling. The strength of trapezoidal interface, its interface strength and bulk material. Flexible flange connection method: in the plastic flange place steel looper flange, and then put the appropriate gasket, string into the specified bolt, tighten it.
Q:What is the difference between a grooved pipe and a lining pipe?
A grooved pipe is a piece of pipe that is connected by a clamp, and refers to the way of connection.The lining pipe means that the pipe is lined with a layer of plastic.The groove pipe fittings can be lined with plastic pipe fittings, otherwise, the lining plastic pipe fittings can also be groove fittings.
Q:PE plastic pipe surface is concave, how could it happen?
Before the pipeline connection, the pipe, pipe fittings and accessory equipment shall be checked according to the design requirements, and the appearance inspection shall be conducted at the construction site, and may be used in accordance with the requirements. Main inspection items include pressure rating, external surface quality, matching quality, consistency of material, etc..
Q:Who knows the size of the PVC pipe and what is the maximum and minimum size?
The physical properties such as molecular weight, crystallinity and softening point of PVC change with the polymerization conditions (temperature). PVC resin is used as base material and mixed with various additives such as stabilizer, plasticizer, filler, colorant and modifier. It is plasticized, molded and processed into PVC resin plastic. PVC material has light, heat insulation, heat preservation, moisture-proof, flame retardant, simple construction and so on. Specifications, colors, patterns, and very rich decoration, is widely used in production and life. For example, PVC water pipes, PVC plastic doors and windows, and plastic toys containing PVC, wires and cables.
Q:Are the elbow and three - pipe fittings installed in the water supply and drainage pipes included?
This needs to consider the pipeline material, under normal circumstances, the steel pipe welding connection, the thread connection, the plastic pipe plug connection (mainly for the PVC pipe) are not calculated pipe fittings, included in the quota;The following pipes need to be individually calculated:1, steel pipe groove or flange connection, need to calculate groove pipe fittings, flange piece;
Q:What's the size of the PPR pipe?
After heating, take out the pipe and pipe fittings and connect immediately. When the pipe and pipe fittings are joined together, if the location is not correct, a little adjustment can be made, but the twist angle shall not exceed 5 degrees. Don't push the tube too deep because it may reduce the inner diameter and even clog the pipe
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:What are the differences between electrofusion welding, hot melt welding and welding connection?
Hot melt is to use materials for heating and melting of special equipment, and even after the material is cooled. The hot melt pipes used in the project are all hot melt, and the construction is convenient and economical;
Q:What are the specifications of PVC tubes?
PVC drainage specifications, I know, 200mm-2500mm caliber, Shandong Mu Feng plastic pipe to do drainage that piece is pretty good, you can look at, as if the largest domestic should be able to do three meters caliber
Q:Doubts about the connection of plastic pipe and steel pipe flange?
Pipe diameter is GB, such as DN100, DN150 and so on, the path is the sameBut the pipe will vary with the material used and the thickness of the materialBut the flange is the samePlastic pipes are the same size as flanges used in steel pipesWhen you refer to the piping design manual and the hardware manual on the plumbing and flanges, you'll see
