RPMP handling should be noted: Fiberglass Reinforced Plastic Pipe in the process of loading and unloading Beware beat or hit, try to gently; before handling handling tools to check well in advance of the stability and reliability of the ceiling, if handling tools instability will lead glass pipe member has been hit hard in the loading and unloading process, quality problems; fittings in the lifting of the process to identify the two support points to ensure that the tube in the air balance, prohibited two with a rope leash fittings reach for the hanging glass pipe changjia, pipe surface is smooth, rope fall off from both ends of the tube, resulting in pipe fall rupture from the air; tubular handling process used to choose the strength and toughness, high softness to the rope or belt, to prevent midway key slip or scratch the surface of the tube. Before the pressure test, meet the following conditions: a. Within the test range of pipe installation in addition to painting, insulation, but has been completed according to design drawings, installation quality compliance. b. Welds and other parts of the yet to be tested paint and insulation. c. Expansion joints on the pipeline has set up a temporary restraining means. d. Test pressure gauges have been checked, and in the cycle, the accuracy of not less than 1.5, the full scale value table should be 1.5-2 times the measured maximum pressure, pressure gauge must not be less than two. e. Liquid or gas to meet the pressure test requirements is now ready. f. According to test requirements glass pipe, the pipe has been reinforced. g. Independent pipeline system to be tested or to take other measures have been separated by a blanking plate. h. Road to the safety valve to be tubes and instrumentation components, etc. have to be removed or isolated. i. Test program has been approved and carried out technical tests. ⑤ hydraulic test shall comply with the following provisions: a. Before the test, inject the liquid should be drained of air. b. When the test environment temperature should not be lower than 5 ℃, when the ambient temperature is below 5 ℃ glass pipe manufacturers, to take freezing measures. c. Pipeline test pressure of 1.5 times the design pressure. d. When the pipeline design temperature is higher than the test temperature glass pipes, test pressure is calculated as follows: Ps = 1.5P [σ] 1 [σ] 2 wherein Ps ---- test pressure (gauge pressure) (MPa); P ---- design pressure (gauge pressure) (MPa); the design temperature for 2 ---- Xu [σ] pipe; [σ] test temperature under 1 ---- Xu pipe stress (MPa) stress (MPa). When [σ] 1 [σ] 2 is greater than 6.5, taking 6.5. Glass pipe changjia_ Xiong Wong Tai (Live) _ Wulanchabu glass pipe provided by Xiong Wang Thai Plastic Products Factory.
