The hard core method adopts the core extrusion process to extrude the inner rubber tube blank, which directly uses the extruder to cover the inner rubber tube blank on the iron core, instead of the traditional casing process, and simplifies the process flow. Shanxi Acid and alkali resistant pipe The billet forming adopts the process method of intertwining outer film and steel wire braiding forming. Similar to wrapping water wrapped cloth, the overlapping width is 1/2 of the film width. This process method can replace the method of wrapping outer film by extruder or by hand, reducing energy consumption and cost. We all know that the reinforcing layer and reinforcing layer of the rubber hose are the main force bearing parts, which are used to bear the load pressure. The factors determining the stress condition of the reinforced layer of the rubber hose are determined by the tension of the braided steel wire and the braiding angle. The high-speed steel wire hose braiding machine developed by our factory has introduced the advanced technology of foreign braiding production lines, and integrated the characteristics of domestic braiding machines. It integrates the advanced functions of hydraulic brake hose braiding production line, such as horizontal mechanical transmission, automatic lubrication, and so on, to develop equipment with high productivity and high degree of automation. The range of braiding diameter can be achieved Ф 6— Ф 25 Long core rubber hose (reinforcement layer). It fills the gap of domestic knitting production equipment, which can be widely used in rubber and plastic hose, rubber hose (reinforcement layer) knitting production equipment. The structure of high-pressure rubber hose is composed of four parts: inner liner, inner rubber layer, skeleton layer, middle rubber layer and outer rubber layer. Acid and alkali resistant pipe Where can I find it? In case of direct contact with the conveying medium, the synthetic rubber with good medium resistance, high tensile strength, high constant tensile stress, small compression permanent deformation and easy processing is usually selected. In order to meet the use requirements of strong polar medium resistance, the inner liner is composed of polytetrafluoroethylene layer and rubber layer, and a layer of film or adhesive is added on the surface of the inner liner to improve the adhesion with the skeleton material.

Shanxi Acid and alkali resistant pipe It is used in transportation, construction and other industries. Correct procurement can not only save procurement costs, but also ensure its operation safety. The following series will introduce some purchase suggestions, hoping to help you. Suggestion 1. Determine the type of hose brand to be purchased according to the connection equipment and budget of sandblasting hose, such as high-tech equipment. Naturally, it is necessary to buy large brand sandblasting hose. However, if it is industrial and mining equipment with extremely fast scrapping speed, general quality is enough. Recommendation 2. The price of sand blasting hose with uniform quality grade is also different, especially for large-scale procurement, the price difference will be obvious, so it is necessary to have three quality grades to determine the final partner. Suggestion 3: Select appropriate channels. Sand blasting hoses are usually purchased in large quantities, which means that their turnover is relatively large. Therefore, reliable channels need to be selected to ensure the safety of their own loans. Acid and alkali resistant pipe Where can I find it? The purchase of sand blasting hose components is also described in the model. High pressure hose assembly, pipe body specification (inner diameter, number of pressure layers, winding or braiding), joint type (national standard or Eaton), protective layer type, length and other parameters are the basic data for determining hose assembly.

Shanxi Acid and alkali resistant pipe There are many specifications. Different installation positions require different specifications of cloth clamping sand blasting pipe, and the specification selection of cloth clamping sand blasting pipe has different requirements. The following small series will briefly introduce them to you: 1. Temperature: The selection should be based on the ambient temperature when the cloth clip sandblasting pipe is working. In case of high temperature, the temperature correction pressure shall be determined according to the working pressure and temperature correction coefficient of the cloth sanding pipe under high temperature to determine the correct pressure level. 2. Pressure: when selecting the cloth clip sandblasting pipe, check the nominal diameter and pressure gauge of the corrugated cloth clip sandblasting pipe according to the actual working pressure of the hose to determine whether to use the stainless steel mesh sleeve type. 3. Size: select the joint type, size of cloth sanding pipe and hose length according to the size of cloth sanding pipe. 4. Medium: determine the material of each part of the hose according to the chemical properties of the material medium transported in the cloth sanding pipe and the corrosion resistance of the hose material. 5. Status: According to the use status of the hose, refer to the correct use and installation method of the cloth clip sandblasting pipe and the length of the hose in the settlement compensation. Therefore, Acid and alkali resistant pipe Where can I find it? According to the actual pressure of the system, the higher the working pressure of the cloth clamping sand blasting pipe is, the normal operation of the system can be ensured, and the appropriate cloth clamping sand blasting pipe is selected.

Shanxi Acid and alkali resistant pipe Vulcanization of technical performance indicators is an important process to enhance the adhesive strength between rubber and reinforcement layer and make it a whole in rubber hose manufacturing, and also an important link to ensure and improve product quality. In order to obtain good pulse performance and service performance of steel wire reinforced rubber hose, in addition to reasonable structure and formula, it is necessary to ensure the compactness of vulcanized hose. In order to meet this performance requirement, the traditional vulcanization method is to wrap the water in water cloth on the semi-finished hose before vulcanization, make braided hose or steel wire for reinforcement and fastening, and vulcanize in batches with steam vulcanization tank. Since the performance requirements of medium and low pressure hoses are low, the rubber hose can also be directly put into the curing tank without fastening. Although water wrapped cloth vulcanization can also increase the compactness of the hose, its appearance is poor. In order to obtain the smooth outer surface of the hose, the lead coating vulcanization method is widely used at home and abroad. For decades, people have been using this method as an effective method to vulcanize and strengthen rubber hoses, especially high-pressure rubber hoses. So far, many domestic and foreign manufacturers are still using this method to produce rubber hoses. But the fatal disadvantage of this method is that it pollutes the environment. Acid and alkali resistant pipe Where can I find it? The main control function of the air compressor station unit is to exhaust more air. According to different structures, it can be divided into full hose, cloth hose, steel braided hose, etc. According to different uses, it can be divided into air hose, water suction hose, water delivery hose, heat resistant hose, acid (alkali) resistant hose, oil resistant hose and special hose., It can be closed within the specified range.

1. The use of protection cannot be ignored: the long-term use of high-pressure sand blasting hose joints at home usually does not cause concern, but excessive use and improper protection also buried the hidden danger of joint cracking to a certain extent. It is understood that the service life of the joint is usually 200000 times, and it should be replaced after long-term use. When using the side, Acid and alkali resistant pipe Where can I find it? Care should be taken to close and open as gently as possible and not to rotate the knob of the hose connector repeatedly. 2. Differentiation of quality can be based on standard evidence collection. It is understood that it is still difficult to determine the cause of joint cracking. At present, the National Bureau of Technology and Quality Supervision has issued recommendations for sealing nozzles and hose specifications. These two specifications perfectly adjust the quality specification target of connectors and hoses. Consumers can go to the quality inspection department to check the torsional strength of the connecting hose, the tightness of the connecting spool and the strength of the connecting materials. If the content of standard rules cannot be met, it will be attributed to quality problems, which can serve as a strong basis for expression. 3. The appearance of hose connector is difficult to distinguish between good and bad. In order to pursue profits and reduce costs, many manufacturers currently use selected cast iron (easy to rust) and zinc alloy (non anti-corrosion) as materials to produce high-pressure sand blasting hose joints, which causes product quality problems. It is understood that the quality of connectors and hoses is not up to standard, Shanxi Acid and alkali resistant pipe The strength function and sealing function of high-pressure sand blasting hose joints are not up to standard due to problems such as materials and wall thickness, which should be paid attention to by consumers.
