The use of PPH pipe can eliminate galvanization, the long-term temperature of the pipe is 90 degrees Celsius, the short-term temperature can reach 120 degrees Celsius, and the inner wall is smooth, rust-free, and small anti-flow for long-term continuous use. PPH pipe welding is hot melt welding, and various specifications of hydraulic or manual plastic pipe hot fusion splicing machines are selected. When punctual, tighten the fastening screws at both ends of the clamp one by one to avoid the pipe section being unlevel;
The lower half of the welded surface is touched by hand so that the two seams are horizontal. When the requirements are not met, the screws at both ends are tightened by conditioning to make the weld seam free of mistakes; HeatingTake out the heating plate that has reached the required temperature from the thing placement rack, put it on the operating frame, and push the hydraulic clamp while leaning on the side of the welding surface to make the pressure reach the required welding pressure, so that the welding surface is flat and the section is avoided.
The general reason for the smell of plastic products is often the use of retractable materials and residual additives, which will emit irritating gases; PPH pipes can be buried in the ground, and heavy pressure should be avoided on the top after the laying is completed, so as not to cause the pipeline to bend after being buried, and the pipe joints are prone to leakage and liquid leakage due to uneven pressure for a long time.
PPH tubing has a wide range of use, and freezing and cracking may occur when the temperature is lower than minus 20 degrees, so it is necessary to consider the environment in which it is used; At the end of the bracket device, the prefabricated connection is tied to the hemp rope upper line hoisting device to reduce the operating load and accelerate the pipeline device. Add pipe grooves, pipe trenches, etc. in the PPH pipe laying, and add maintenance ports or maintenance doors at the tube wells after completion.
