FRPP pipes are basically used in central air-conditioning systems. They can also be used in purified water systems. Even building heating systems and heating systems, FRPP pipes are competent. Those of us who are not familiar with FRPP pipes certainly don’t know what to pay attention to when choosing pipes. The editor probably also knows that if you want to use FRPP pipes for a long time, the temperature cannot exceed 70 degrees Celsius. If it is used for cold water, 40 degrees Celsius is enough. Of course, these are not topics we need to worry about. There are specialized people who can help us solve our difficulties.
FRPP pipes (glass fiber reinforced polypropylene pipes) are produced from glass fiber modified polypropylene materials treated with coupling agents. They are corrosion-resistant, high temperature resistant, high pressure resistant, hygienic and non-toxic, and can be recycled. Suitable for industrial corrosive liquid transportation (such as acid and alkali liquid) and municipal water supply and drainage systems, etc. FRPP pipe (glass fiber reinforced polypropylene pipe) is produced from glass fiber modified polypropylene material treated with coupling agent. It is corrosion-resistant, high-temperature resistant, high-pressure resistant, hygienic and non-toxic, recyclable, and suitable for corrosive liquid transportation ( Such as acid and alkali solutions) and municipal water supply and drainage systems. It has excellent impact resistance and tensile strength, is light in weight, and is easy to install and maintain. FRPP pipes are widely used in chemical industry, chemical fiber, chlor-alkali, dyes, water supply and drainage, food, medicine, sewage treatment, electrolysis and other industries due to their unique properties.
The FRPP pipes purchased daily are basically 5 meters in size. The editor below uses a table to show you the specifications of FRGG pipes. Long service life - under rated temperature and pressure conditions, FRPP pipes can be safely used for more than 50 years. Excellent corrosion resistance - FRPP pipes are resistant to corrosion by most chemicals and can withstand corrosion by high-concentration acids and alkalis with a pH value ranging from 1 to 14 over a wide range.
Higher stiffness - due to the addition of glass fiber reinforced materials, FRPP pipes are not easily deformed. Heat-resistant, thermal insulation and energy-saving - the maximum operating temperature of FRPP pipes is 95 degrees. The thermal conductivity of this product is only 1/200 of that of steel pipes, so it has good thermal insulation performance. Reliable connection performance - the strength of the hot-melt joint of FRPP pipes is higher than that of the pipe body, and the joints will not be disconnected due to soil movement or load. Good construction performance - the chemical composition of the welding rod material must ensure the strength requirements for pipeline welding. When hot air welding, the heating temperature should comply with the following regulations: 190-240℃.
The welding rod and welding surface must be clean and clean. The welding rod and pipe must be in a molten state at the same time for welding, and there should be no burning or decomposition. The welds should be arranged closely and there should be no gaps. The surface of the welding seam should be smooth, and there should be no corrugation or blowing of the welding rod. The strength of the weld shall not be lower than the strength specified in the design. The weld should cool naturally. The heating temperature of pipes during hot-melt butt jointing should comply with the following regulations: 190-240°C. During hot-melt docking, the pipes to be docked should be fixed horizontally on the clamp of the docking equipment, so that the two connecting pipes remain in a horizontal position, and the two pipes should be aligned with the center. Hot melt butt joints should use welding equipment with temperature regulation. Control the hot melt temperature and hot melt time according to the pipe material. And maintain a certain docking thrust. The hot-melt butt joint surface should cool naturally.
The editor only knows about this much, and of course he is not as good as the professionals. The wall thickness of frpp pipe fittings must be no less than the wall thickness of pipes of the same specification. When we choose pipe materials, we must clean the pipes and pay attention to tight fit when welding. The material of FRPP pipe is very light, and the welding process is not complicated. Workers will find it very convenient and fast during construction, and its cost is very low. Simply put, frpp is the best choice.
