[Tianjin Jinzhong Ji HVAC purification equipment to recommend the star product - Pipeline Project] duct installed in place according to the site, can be connected into a length on the ground, with the lifting of the method in place, you can lookout tube a section of land on the bracket, section by section connections. General order is the first dry pipe, after the branch pipe. Riser installation is usually installed from the bottom up. Post-installation leveling position, alignment, designed to meet the requirements specified. Duct installation should be noted: 1, when the duct using flangeless connection, the interface should be tight and firm. The four corners of the rectangular duct positioning and sealing arrangements must be applied. Duct connecting the two planes should be straight, not misplaced and distorted. 2, mounted on a bracket round wind pipe bracket should be located. 3, the wind piercing the roof should be set outside the rain cover. 4, easy to produce condensate transport duct, the slope of the design requirements should be installed. Duct bottom ventilation ducts can not have a longitudinal seam project, if the application sealed seams. 5, steel duct with brick, concrete duct connectors should conform airflow direction, wind pipe and duct joint surface must be sealed. 6, the branch duct insulation, hangers should be located in the outer insulation, and not damage the insulation. 7, air hose and a vertical mains plug, the interface should be set wind adjustment. After the air duct tightness test tube installed, the system pressure should be closely rating test, air leakage should be in line with national norms "Ventilation and Air Conditioning Engineering Construction Quality Acceptance" tightness test should GB50243 the requirements, the system meets GB50243 specification appendix leaked assay and amount of air leakage testing. Tightness test should be low pressure piping systems using sampling, sampling rate of 5% and less than one sampling system. When processing and leaked test failed, the sampling rate should be required to do the amount of air leakage test. Tightness test medium voltage systems, piping specifications should be under strict eligibility leaked detection of air leakage duct system for sampling, the sampling rate of 20%, and less than one sampling system. High-pressure system should be fully carried out air leakage test. [Tianjin Jinzhong Ji HVAC purification equipment to recommend the star product - galvanized pipes] (a) operating conditions 1, should have a centralized processing pipeline using open, bright, clean, smooth surface, no wet plant . 2, the job site have the appropriate processing of the necessary tools, facilities and power and reliable security guards, and fire equipment. 3, the wind should be approved drawings produced by the review of a large sample chart, system diagram, and a member of the technical construction of written tests, quality and safety. (B) a material requirements, the main material applicable plates, steel should have the factory certification or qualification documents. 2, stainless steel plate should have acid corrosion resistance at high temperatures, the board may not have scratches, scratches, rust plate, and depression and other defects. 3, aluminum sheet should have good ductility, electrical conductivity, thermal conductivity and acid resistance, surface scratches and wear not. 4, industrial equipment: gantry bending machine, power punching, manual electric shears, chamfering machine, locking machine, beading machine, folding party machine, a sewing machine, vibration curve Jane plate machine, rolling machine, hydraulic pliers, nail pliers, electric Riveter, bench drill, hand drill, punching machine, cutting, flange machine, spiral tube machine, electricity, gas welding equipment, air compressors, paint, painting and other equipment and stainless steel plate ruler, protractor Square, zoned regulation, stylus, Yang Chong, hammers, wooden hammer, clappers and other small tools. Plate thickness exhaust system can refer to high-pressure system.
