  FRPP tube (glass fiber reinforced polypropylene Tube)
 It is produced with glass fiber modified polypropylene material treated by coupling agent. According to hg20539-92 standard, the specification is DN 15-dn 1500 mm, and the nominal pressure is 0.4-1.0 MPa. It is corrosion-resistant, high-temperature resistant, high-pressure resistant, hygienic and non-toxic, and can be recycled. It is suitable for corrosive liquid transportation (such as acid-base solution) and municipal water supply and drainage system. It is widely used in chemical industry, chemical fiber, chlor alkali, dye, water supply and drainage, food, *, sewage treatment, electrolysis and other industries. catalog one Pipe standard 2 characteristics 3 connection method 4 performance 5 specifications 6 connection assembly 7 quality control 1. Pipe standard
 Hg 20539-92 was performed for FRPP tube[ 1] 2 characteristics
 Long service life --- under the condition of rated temperature and pressure, FRPP pipe can be safely used for more than 50 years. Excellent corrosion resistance - FRPP pipe can resist the corrosion of most chemicals, and can withstand the corrosion of high concentration acid and alkali in the pH range of 1-14 in a large range. High stiffness: the FRP pipe is not easy to deform due to the addition of glass fiber reinforced material. The thermal conductivity of the product is only 1 / 200 of that of the steel pipe, so it has good thermal insulation performance. Reliable connection performance: the strength of the hot-melt joint of FRPP pipe is higher than that of the pipe body, and the joint will not be broken due to soil movement or load. Good construction performance: light weight FRPP pipe, welding The process is simple, the construction is convenient, and the comprehensive cost of the project is low. 3 connection method

Welding rod and Pipe Welding must be carried out at the same time in the molten state, without scorching and decomposition.  weld line The arrangement should be close without gaps. The weld surface shall be flat without waviness and electrode blowing. The strength of the weld shall not be lower than that specified in the design. The weld should be cooled naturally. Hot fusion butt joint of FRPP pipe The heating temperature of pipes during hot-melt butt welding shall meet the following requirements: 190-240 ℃ During hot-melt butt welding, fix the butt joint pipe horizontally on the fixture of the docking equipment, so that the two connecting pipes keep horizontal position, and the two pipes should be aligned with the center. The welding equipment with temperature adjustment shall be adopted for hot melt butt welding. According to the pipe material, control the hot-melt temperature and time. And maintain a certain docking thrust. The joint surface of hot melt butt joint shall be cooled naturally. 4 performance
