Buried polyurethane insulation pipe handling and transportation 1, insulation pipe handling, can be used at both ends of the two hook Diaozhu steel or with a width greater than 50mm tape loading and unloading, the small diameter pipe insulation and easy to manual handling. 2, in the handling, should be done gently, to prevent damage, non-dragging on the ground. 3, pipe piling, loading and unloading is prohibited to use iron pry or rope tied directly to the outer casing. Model specifications polyurethane insulation polyurethane insulation Buried pipe fitting Note 1, we must truly understand the two ways Buried Heating Pipeline: Buried and without compensation to make up for direct burial, really two ways to master their works Features and Applications for a reasonable choice in the design, the construction of safe, reliable and economical. 2, after entering the test seriously, before construction is necessary for the production of polyurethane manufacturers to conduct research, to refuse the use of substandard pipe insulation. 3, in the pre-buried pipe construction, polyurethane insulation pipe welding work is a key project quality assurance. 4, to meet pressure conditions, it is necessary to suppress the importance polyurethane insulation pipe. Firstly irrigation drain air, then do two steps: 10 since the beginning of the regulator without leakage. Strength test: After the pressure in the pipeline was increased to 1.5 times the working pressure; with 1kg hammer around the weld seam inspection one by one beat, tightness test: when the pressure inside the tube down to the working pressure for 30 minutes without leakage and pressure drop is not more than 0.2 atm is qualified; specifications should check pressure test records. 5, due to polyurethane insulation buried, project acceptance carefully, if final acceptance is not serious, detailed information is not completed, it will affect the future use. 6, joints, backfill should be in the pipeline pressure test. Completion of the measurement, can be carried out after the cleaning is completed, and the essential characteristics of construction by polyurethane insulation backfill sand predetermined thickness, do not cut corners. 7, polyurethane insulation pipe insulation shall only be fitting scene after the pressure test, the joint insulation construction site. This is an element of pipeline construction is unique polyurethane insulation construction quality directly affects life.
