Damage to wear-resistant hoses under high temperature conditions

Temperature can sometimes compromise the life of wear-resistant pipes. High temperature will accelerate the damage of chemical substances to rubber raw materials, which depends on the ratio of polymer and chemical substances. There are some compound rubbers that are stable at room temperature, but are likely to fail rapidly at high temperatures. When chemicals come into contact with compounded rubber, they generally swell. Under a certain expansion coefficient, the hose may operate normally in a static data environment. If it undertakes a relatively large bend, the hose will quickly become invalid. Braided stainless steel wire hose is suitable for transporting chemical gases and organic solvents under high temperature and high pressure. In addition, the pipe body can also give a flexible connection between the seamless steel pipes in the fixing system. It is widely used in mining hydraulic support, automatic hydraulic transmission system of oil and gas field mining machine, mining engineering and other agricultural fields, especially as a component of jackhammer. The tube body can work continuously in an environment with a resistance of -40°C to 100°C and a maximum temperature of 125°C. The surface layer of stainless steel wire woven high-pressure hose can be divided into two types: smooth surface and textile surface. Gas chemical raw materials, also known as oil and gas field additives, refer to chemical additives used in the whole process of oil and gas field exploration, well completion, oil field, irrigation, enhanced oil recovery, Taobao collection and transportation; in a broad sense, it refers to oil and gas fields, exploration, oil and gas collection and transportation. , EOR and other links, the development and utilization of various chemicals. Crude oil and natural gas chemical products can be divided into five categories according to their main uses: general chemicals, drilling chemicals, oil and gas extraction agents, and petrochemical equipment. 150PSI white food suction and discharge pipe: The pipe body is mainly used to inhale and remove edible substances, such as human fat, greasy food and alcoholic beverages (up to 75 alcohol content). The internal structure is made of NBR rubber that meets the requirements of FDA and its 3A. The surface layer is made of white NBR/PVC rubber mixed rubber, which has good wear resistance, air oxidation resistance, alkali resistance and weather resistance. In order to ensure that the body of the tube works continuously in the nature with a stable working pressure of 150psi, the tube body is reinforced with high support force coiled textile ropes and its 4 layers of relatively high agility helical steel wires.

Stainless steel wire braided hose is a new product of wear-resistant rubber hose. It is light in weight, small in diameter and easy to assemble. It is suitable for various environments where mortar or raw materials are transported, and high-pressure systems are used for various transportation. Substances and chemical raw materials. For the production of high-pressure and wear-resistant hoses, the application temperature is between -40° and 120°. The imported UPE with low flow resistance and smoothness is used as the raw material of the connecting pipe, and the high-strength steel wire is used as the reinforcement layer. Abrasion-resistant, all-day raw materials.

Like other equipment accessories, each different type of spare parts product has There are different styles and their specifications and sizes. For different customers, their application places and requirements are different, and the requirements for new products are also different. When choosing API 7K crude oil wear-resistant hoses, we should be concerned about this situation. Here we recommend that you pay attention to the model specifications and specifications of your own machines before choosing, and see what type of soft hose you actually need. Tubes are used together, so that the effect used in the middle and later stages will be better.
