What is a carbon -free insulating hose?

Carbon -free insulating gel tube is a spare parts commonly used in medium -frequency furnaces. According to the size of the electric furnace, choose a carbon -free insulating tube with different insulation coefficients. Affuvenal, a few large furnaces in the carbon -free insulation tube requires the insulation coefficient of more than 12,000 volts, and there are some special equipment, large steel mills, and the insulation coefficient of carbon -free insulation tube required by transformer factories will reach more than 12,000 volts. The National Petroleum Diamond Midbar Bidding Committee, which was established by the National Standardization Management Committee, is mainly engaged in the standardization of drilling, production, mining equipment and tools in the oil and gas industry.
At the same time, he also serves as the ISO/TC67 Commission of the International Standardized Organization and the Domestic Hand of the United States Petroleum Society (API). In addition, our company has successfully obtained certification certificates such as the API7K16D of the association, indicating that the high -pressure wear -resistant hose produced by our company has corresponding international standards. Pipeline transport 180 degrees Celsius steam generally uses rubber high -temperature and high -pressure steam hose. The inner and outer layers of this hose are used in three yuan (EPDM) rubber. One or multi -layer steel wire is woven in the middle. Steam transportation, in addition, its working pressure can also increase according to the number of steel wire preparation layers used in its enhanced layer, maximizing the work pressure of 20MPa and the blasting pressure of 170MPa.
Type C and D of concrete wear -resistant hose (A, B, C, D pressure from low to high): The work pressure is about 6MPA ~ 8MPa, 78MPa ~ 8.58MPa, which have high requirements for high pressure resistance, enhance The layer is generally the structure of the wire wound. And under high -pressure use conditions, its wear resistance requirements also meet the original conveying volume, which is relatively high in internal glue. Synthetic abrasion -resistant rubber that generally collect special processes is generally collected as internal glue. The rubber tube was ruptured and the steel wire was rusty near the crack. If the high -voltage oil pipe is ruptured, the peeling of the plastic layer is inspected and found that the woven and entangled steel wire near the cracks are rust. This is mainly due to the humid or corrosive substance of the outer gum layer, which weakens the strength of the rubber tube and causes the high pressure to rupture.
This situation is generally accompanied by the outer layer break, abrasion, or severe deterioration, which makes the outer layer lose the protective effect on the enhanced layer. At this time, it is necessary to check and exclude bad factors such as mechanical destruction, chemical corrosion, and high temperature baking of the external rubber layer, and then replace the rubber tube. Steaming tube, that is, steam hose. It is used for cooling water, engine engine cold and cold water, food processing, especially the hot water and saturated steam of dairy products, which can resist thinner (low concentration) pH. Structure: Steam hose, like ordinary industrial hose, is composed of internal glue, outer glue and middle layer. Steaming tube with woven steel wire and wrapped wrap. Commonly used internal and outer glue materials are made of heat -resistant, steam -resistant, oxygen resistance, and excellent EPDM materials with excellent performance of oxygen and chemicals. The middle layer is generally weaving lines or preparation of steel wires to enhance the pressure range of the rubber tube.
