Description
Technical Field
The invention belongs to the technical field of gas pipeline detection, and particularly relates to a gas pipeline detection system.
Background
In the municipal pipe market of China, plastic pipes are steadily developed at present, PE pipes, PP-R pipes and UPVC pipes all occupy a place, and the strong development potential of the PE pipes is the most remarkable. PE pipe's application is extensive. The water supply pipe and the gas pipe are two largest application markets. The PE resin is polymerized from monomer ethylene, and can obtain resins of different densities due to different polymerization conditions such as pressure and temperature during polymerization, and is classified into high density polyethylene, medium density polyethylene and low density polyethylene. When processing different types of PE pipes, the corresponding resin grades are selected according to different application conditions, and the requirements on an extruder and a die are different.
The gas pipe must bear certain pressure, and PE resin with high molecular weight and good mechanical property, such as HDPE resin, is usually selected. HDPE resins have low tensile strength, poor compression resistance, poor rigidity, poor dimensional stability during molding and processing, and are difficult to join, and are not suitable as materials for water supply pressure pipes. However, due to its high hygienic standard, LDPE, especially LLDPE, has become a common material for gas pipes. LDPE and LLDPE resins have small melt viscosity, good fluidity and easy processing, so the selection range of the melt index is wide, the MI is usually between 0.3 and 3g/10min, cracks occur in weather change or other external reasons during the use process of a gas pipe, but the cracks cannot be found from the outside, if the cracks cannot be detected in time, the gas leakage can be caused by the continuous deterioration of the cracks, and therefore, the problems are improved in the text.
