Glass pipe specification, Xiong Wang Thai (certified), Baoding glass pipe provided by Xiong Wang Thai Plastic Products Factory. Xiong Wang Thai Plastic Products Factory (www.wangtai668.com) is specialized in the "plastic tube, MPP power tube, CPVC pipe electricity, irrigation pipes, HDPE pipes, p" of the enterprise, the company of "honesty, hard service" concept, to provide you with the highest quality products and services. Welcome to inquire! Contact: Fengjing Li. Before the pressure test, shall meet the following conditions: a. Within the experimental range of pipeline installation project in addition to painting, insulation outside, according to the design drawings have been completed, the installation of quality to meet the requirements. 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 restraint device. d. Test pressure gauges have been checked, and in the period, which shall not be less than 1.5 accuracy, full scale value should be measured Table 1.5-2 times the maximum pressure FRP pipe plant, pressure gauges shall not be less than two. e. Liquid or gas to meet the pressure test requirements is now ready. f. According to test requirements, the pipeline has been reinforced. g. Piping system to be tested and have nothing to do or take other measures to be separated by a blanking plate. h. Road 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, note should be drained of liquid air. b. During the test the ambient temperature not less than 5 ℃, when the ambient temperature is below 5 ℃, freezing measures to be taken. c. Pipeline test pressure of 1.5 times the design pressure. d. When the pipe is higher than the design temperature of the test temperature, the 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] Xu FRP pipe, pipe under 1 ---- test temperature stress (MPa) stress (MPa). When [σ] 1 [σ] 2 is greater than 6.5 glass pipe, take 6.5. Glass pipe with its unique and strong corrosion resistance, smooth inner surface, low transport energy consumption, long service life, in general, the life of the glass tube in more than five decades, convenient transportation and installation, low maintenance and low total cost many advantages in the oil, electricity, chemicals, paper, urban drainage, sewage treatment plants, desalination, gas transportation and other industries to achieve a wide range of applications. Glass pipe is a both a hardness of the glass, high temperature, corrosion-resistant properties, but also has the same characteristics of hard steel shatterproof glass pipe specification, and can stand shoulder to shoulder with the steel composite pipe materials. With urbanization, the face of the balance and protect the population, resources and environment, governments at all levels in the year to increase investment in urban infrastructure, combined with advanced science and technology needs, pipes, fittings and constantly enrich the varieties and specifications, production increasing the quality continues to improve, especially glass pipes developed rapidly, becoming a mainstay of the casing.
