Several Considerations for Selecting High Temperature Hose

High temperature hose is used in high temperature water vapor, oil, chemicals, air and various liquid transfer pipe. In the industrial field, many manufacturing processes require the use of high-temperature hoses, including metallurgy, automotive, paper, casting and other industries. Because the liquid or gas to be transferred must operate in a high temperature environment, it is important to choose the right high temperature hose. When choosing a high temperature hose, the following factors need to be considered:

How to repair the PE pipe after damage? The method is as follows

PE pipe in the production process due to the impact of the environment, may cause some defects on the surface, the more common is the surface roughness or scratches. There are many reasons for this defect, so there are many corresponding repair methods. If it is found that the surface of the PE pipe is rough, it may be caused by the high or low temperature of the host head. For example, when the temperature of the core mold is low, the body temperature is too low to cause the surface roughness; the cooling water temperature is too high to cause the surface roughness. In this development situation, the cooling water temperature should be appropriately reduced. At the same time, we should also check whether there is blockage and insufficient water pressure in the waterway. And check the heating ring, raw material production performance, etc.

How to connect PE pipe with metal pipe and valve fittings?

The bolts on the flange plate are fixed with metal pipes such as PE pipes connected by flanges, which is not only easy to operate, but also short in construction period. Flange connections are mainly used to connect PE pipes to metal pipes or valves, flow meters, pressure gauges and other auxiliary equipment. Flange connection is mainly composed of PE injection flange, steel or aluminum flange, gasket or sealing ring, bolt and nut. Flange connection is the process of tightening bolts and nuts from beginning to end, so that the flange joint is in close contact with the flange parts. PE pipes can be connected to other metal pipes.

Application of Metal Corrugated Pipe in Construction Industry

For many years, the research in the construction industry requires metal corrugated pipes, especially on prefabricated beams. In the prestressed part, the prestressed steel strand must pass through the corrugated pipes. When the concrete strength reaches a certain strength, the prestressed steel strand is tensioned. After pulling, grouting is required and then sealing is performed. Therefore, each prefabricated beam needs corrugated pipes, and the quantity is relatively large. In addition, the current engineering construction industry is so prosperous, and the national investment is large enough, so there is a lot of demand.

What is the reason why there are particles on the surface of EPDM extrusion hose

Extrusion hose surface why there are small black particles. Some silicone manufacturers have consulted us about this problem, so let's briefly discuss what causes this problem. Because there are many reasons, it depends on the composition of the formula and the vulcanization process.

Application of reclaimed rubber in hydraulic hose

The so-called hydraulic hose refers to the high-pressure hose with steel wire braiding or steel wire winding structure. It has particularly harsh requirements on the type and index of the rubber material used, especially the inner hose. So whether reclaimed rubber can be used in the production of hydraulic hose as a new raw material to reduce the cost of various rubber products instead of raw rubber, what kinds of reclaimed rubber can better reduce the production cost of hydraulic hose while ensuring the quality and service life of hydraulic hose products?

Analysis of quality identification method of PP pipe

1, "touch" texture is delicate, whether the particles are uniform. At present, there are mainly white, gray and green colors on the market. Under normal circumstances, recycled plastics cannot be white, so consumers often think that white is good. In fact, this view is rather one-sided. With the update of technology, color is not the standard to distinguish the quality of PP pipe. The quality of the tube cannot solve the problem. Touch it, and the rough particles are likely to be mixed with other impurities.

What should be paid attention to when PP pipe is used in construction?

What should be paid attention to when using pp pipe construction? As a kind of special plastic pipe, because of its perfect performance, it is mostly used in building cold and hot water discharge and switching system in life. So what should we pay attention to in the process of using pp pipe?

Storage mode of PP pipe and its components

PP pipes should be stacked horizontally on the flat ground, bending pipes should be avoided, stacking height should not exceed 1.5m, pipe fittings should be stacked layer by layer, should not be stacked too high. PP pipes and fittings shall be placed in well-ventilated warehouses or simple sheds, and shall not be stored in the open air to prevent direct sunlight. Pay attention to fire safety and the distance from heat source shall not be less than 1m. Pipes and fittings shall be handled with care to avoid oil pollution. Violent impact is strictly prohibited. It is strictly prohibited to touch, throw, drop, roll and drag with sharp objects.

Formulation Design of Cold-resistant Hose Produced by EPDM Rubber/Reclaimed Rubber

EPDM rubber has excellent high and low temperature resistance and aging resistance, and can maintain good service performance for a long time under specified low temperature conditions when it is used to produce cold-resistant hose. EPDM reclaimed rubber is an ideal substitute material for EPDM rubber. When it is used with EPDM rubber to produce cold-resistant hose, the purpose of ensuring quality and reducing cost can be achieved through reasonable formula design. So what should be paid attention to when designing the formula of rubber hose using EPDM/reclaimed rubber to produce cold resistant rubber hose?
