Quality policy:

Zhongfu Lianzhong Group took the lead in the domestic industry through the ISO9001:2000 quality management system certification. Every step of the production of Zhongfu Lianzhong is under strict control, from raw materials into the factory to products leaving the factory. These control processes generally include raw material testing, production process control and finished product inspection and other three main parts.

Zhongfu Lianzhong Group has the first-class physical and chemical laboratory in the industry, with more than 100 sets of various testing equipment, the industry's only microcomputer controlled large-caliber pipeline testing machine, magnetic thickness gauge imported from Germany, etc., can be in accordance with DIN, ASTM, ASME, AWWA,BS, JIS and domestic standards for raw material testing and physical properties of products, such as internal pressure blasting test, stiffness test, heat resistance test, resin thermal deformation temperature test, viscosity test, chemical resistance test, glass fiber strength test and A series of tests, the laboratory was rated as A class laboratory by the Ministry of Chemical Industry.

The structural characteristics of the product：

1. With excellent mechanical and physical properties, the material density of FRP products is usually 1.8-2.1g/cm3, about 1/4 of steel, than steel, cast iron and plastic and other materials are high specific strength, thermal expansion coefficient and steel roughly equal, thermal conductivity coefficient is only 0.5% of steel.

2. Chemical corrosion resistance, long service life · GLASS fiber reinforced plastic has special chemical corrosion resistance, in corrosive medium places, glass fiber reinforced plastic shows incomparable advantages of other materials.

3. High strength and excellent structural performance can adjust the physical and chemical properties of FRP products by changing the resin system or reinforcement materials to adapt to the needs of different media and working conditions.

4, light weight, very convenient installation

Reasonable layering structure is a good guarantee of strength and corrosion resistance of FRP. At the same time, the whole molding method is adopted, so that the equipment will have more perfect corrosion resistance and strength bearing capacity. Large equipment is mainly: lining layer (inner layer, Impermeable layer)+ structural layer + outer protective layer layering structure.

1, Inner layer: by lining resin and organic fiber polyester felt/FRP fiber surface felt enhanced, resin content of more than 90%, good air tightness, very smooth. The layer mainly provides products with anti-corrosion, anti-leakage and other functions. Its thickness is about 0.5mm

2, Impermeable layer: by lining resin and non - alkali glass fiber jet yarn composition. Resin content 70~80%. The main function of this layer is to protect the inner surface layer, improve the internal pressure failure resistance of the lining and prevent the crack diffusion. Impermeable layer and inner surface layer are collectively referred to as inner lining layer, the total thickness ≥4.5 mm

3. Structural layer: the roving yarn with no alkali and no twist is wetted by the resin of the structural layer and then wound by the method of spiral + annular + unidirectional cloth. The resin content of this layer is usually about 30~40%. The function is to withstand compressive stress, tensile stress and various external loads. The wall thickness is determined by reasonable and scientific optimization calculation according to the condition of equipment stress. Fiber winding products have the characteristics of high strength and stiffness, good mechanical properties, and can adjust the winding Angle according to the different use environment and pressure of the equipment, good designability, high quality and stable products.

4, The outer protective layer: because the layer exposed in the atmosphere, vulnerable to light oxygen and climate aging, the design of the layer with aging resistant gelcoat spraying again, while adding UV-9 UV absorber in the resin to prevent light oxygen aging. The thickness of the layer is about 1mm
