What is frpp tubing? frpp pipe is something we can easily see in our life, but we just don’t know much about it. What are the characteristics of frpp pipe? The following Xiaobian will lead you to understand.
What is frpp tubing
The frpp pipe interface is treated with a two-layer structure of radiation crosslinked polyolefin heat shrinkable sleeve, namely polypropylene hot melt adhesive and outer radiation crosslinked polypropylene structure. The materials used meet the requirements of technical specifications. There is a new technology to improve the frpp pipe: first, the pipe is connected to the day table for derusting and cleaning treatment, and then coated with a layer of melted epoxy powder, and then coated with a layer of chemically modified polypropylene powder, the pre-prepared polypropylene composite tape to the joint, and squeezed with a clamp. This force – one method is complicated to operate, but the effect is better.
Through the copolymerization and blending modification of frpp pipe material, the problem of brittleness at low temperature and heat aging property are effectively improved. Through the test, the performance index requirements of special raw materials for submarine pipeline anticorrosive layer are formulated. Based on this, the experimental study of coating technology was carried out. This technology is applied to frpp pipe for the first time, which creates a precedent in domestic sea.
The preferred anticorrosive coating for frpp pipes is a material that is compatible with the body anticorrosive coating and of a quality not less than the body anticorrosive coating. Radiation crosslinked polyolefin thermal shrinkable sleeve (belt) material can be used for on-site repair of the anticorrosive layer, and the thermal shrinkable sleeve (belt) anticorrosive layer should be two layers or two layers. The first layer structure includes solvent-free epoxy resin primer, high shear strength adhesive and radiation crosslinked polyolefin, and the second layer includes hot melt adhesive and outer radiation crosslinked polyolefin.
frpp pipe features
1, long service life. frpp glass fiber polypropylene tubing can be used safely for more than 50 years under rated temperature and pressure conditions.
2, excellent corrosion resistance. frpp tubing is resistant to corrosion of most chemicals and can withstand high concentrations of acids and bases in a wide range of ph values from 1 to 14.
3, excellent wear resistance. The wear resistance of frpp pipe is more than 4 times that of steel pipe when conveying mineral sand mud.
4. High stiffness. Due to the addition of glass fiber reinforced material, frpp tube is not easy to deform.
5, heat resistance, heat preservation and energy saving. frpp pipe has good thermal insulation performance with the highest operating temperature of 95 degrees.
6, reliable connection performance. The strength of the frpp pipe hot melt interface is higher than that of the pipe body, and the joint will not be broken due to soil movement or load.
7, good construction performance. frpp pipe has light weight, simple welding process, convenient construction, and low overall engineering cost.
frpp pipe is made of glass fiber modified polypropylene material treated with coupling agent. It is resistant to corrosion, high temperature, high pressure, sanitation, non-toxic, recyclable, suitable for corrosive liquid transportation (such as acid lye) and municipal water supply and drainage system. Excellent impact resistance and tensile strength, light weight, easy installation and maintenance. FRPP pipe is widely used in chemical industry, chemical fiber, chlor-alkali, dye, water supply and drainage, food, medicine, sewage treatment, electrolysis and other industries because of its unique properties.
