Professional fluid technology professionals can improve mature fluid technology solutions for customers and create value for customers. Here, according to the feedback from customers, we summarize the requirements for the use of concrete conveying hoses for the reference of customers and friends: 1. For the wall thickness of concrete hoses, especially the parts that wear quickly, the safety requirements are higher. 2. When the working pressure is above 1MPa, during high-pressure construction, the wall thickness of the conveying pipe near the pump outlet is 4.3mm, and the wall thickness of the connection between the pouring site and the distribution pipe should not be less than 3.5mm. mm. The fire resistance of the oil hose complies with API Spec. 16D in the fire resistance test, and shows its fire resistance and integrity in the 30-minute open flame test data. The company's products are used in harsh environments such as high risk, high pressure and high temperature, which is enough to prove its reliability. Application of high pressure union: It is used in cement trucks, fracturing trucks, various manifolds, pipelines and other high-pressure equipment. It is an important accessory for transporting oil, water, fracturing fluid and mixed liquids. The product is made of high-quality alloy steel by casting and finishing, and has good mechanical properties, sealing performance and different pressure levels, and is an ideal accessory for oilfield drilling and production operations. The results show that under the same pressure condition, the composite oil hose is better than the same kind of pipe. The utility model can work normally under a relatively small rotation radius, and the bending part of the utility model is always kept in a circular shape, and no folding occurs, the inner wall falls off, is blocked, and the pipe body is broken. Because it is a laminated galvanized sheet structure, the pressure resistance is good, and the hose will expand and contract when the pressure is charged and decompressed. It is mainly used in oil exploration, oil refining, oil pollution treatment, petrochemical storage, animal oil storage, shipbuilding industry, oil port terminals, aviation fuel products, etc. The woodworking ventilation rubber hose has strong wear resistance, and if the copper-plated steel wire is grounded, it can also discharge static electricity, which can be used in the suction and discharge of materials. The high-axis strength of the hose is superior, which can make the transportation of materials smooth; in addition, the rubber hose also has excellent chemical resistance; the bending radius is small, especially suitable for the swing position of mechanical equipment.
