※ Product Introduction
Our company has adopted the best international pipe extrusion production lines from Klaus Maffei and Barton Field in Germany, and insists on using PE from Nordic Chemicals and other companies100、 PE80Gas specific polyethylene blending materials, continuously optimizing production processes, improving employee operational skills and literacy, enable gas pipes to maintain excellent physical and mechanical properties of raw materials to the maximum extent possible. The scientific and standardized management system has achieved traceability of product quality from raw materials to engineering applications; The independently equipped German iNOEX weighing system and ultrasonic online diameter and thickness measurement system ensure zero defects and continuous stable high quality of gas pipes. PE safety gas pipes comply with GB/T15558.2-2023Underground Polyethylene (PE) Pipeline System for Gas Use2Part: Pipes \"standard, with excellent performance such as long service life, good flexibility, resistance to crustal settlement, corrosion resistance, resistance to slow and fast crack propagation, etc. The pipeline system adopts hot melt docking and electric melting connection methods, and the pipes and fittings are fused into one, making the system safe and reliable with low construction costs. Vigorously promoting PE gas safety pipelines is in line with the national guidelines for developing chemical building materials and meets the development needs of improving people\'s living standards.
※ Product Features
1. Strong corrosion resistanceResistant to various chemical media erosion, not corroded by soil acids, alkalis, salts, etc., no electrochemical corrosion, no need for additional anti-corrosion measures.
2. Reliable connectionUsing hot melt docking or electric fusion connection, the joint strength is higher than that of the pipeline body, the sealing performance is good, and there is almost no risk of leakage.
3. Good flexibilityExcellent impact resistance, it does not affect the operation of the pipeline after deformation due to external impact, and can also recover. It can achieve the "joint action of pipe and soil", has strong adaptability to uneven settlement of the pipe foundation, and also has good seismic performance.
4. Excellent resistance to stress crackingHas low notch sensitivity, high shear strength, and excellent scratch resistance, with outstanding resistance to environmental stress cracking.
5. Long service lifeUnder rated temperature and pressure conditions, it can be safely used for more than 50 years, and can be stored or used outdoors without being easily damaged by ultraviolet radiation.
※ Implementation standards
