1. Pressure resistance test
Test the pressure of the high-pressure hose, check whether the pressure resistance of the hose is qualified, whether the tube body leaks, whether the parts are damaged, etc., to determine whether the safety of the hose is good.
2. Air tightness test
The air tightness test of the high-pressure steel wire wound hose adopts dry and clean air or nitrogen or other protective gas as the detection medium to detect whether the hose is leaking.
3. Is the texture of the rubber hose uniform?
Check whether the quality of the high-pressure steel wire wound hose is uniform and whether there are irregularities such as sticking. If so, they will be considered ineligible.
4. Flexibility test
Bend the high-pressure steel wire wound hose moderately to see if it has a certain toughness, so as to avoid abnormal fracture due to bending during use, affecting the normal use of the user.
The high temperature and high pressure hoses mainly include hydraulic pipes and water supply and drainage pipes. Such as continuous casting machine secondary cooling, sintering machine lubrication station, blast furnace drilling machine, etc. For high temperature and high pressure oil pipes, we generally use outsourced asbestos technology for engineering high pressure oil pipes. Since asbestos is made of high temperature resistant materials, the high pressure hose is resistant to pressure, oil and corrosion, and high temperature resistant technology is added on the outside, so it has a longer service life and a wider range of applications. Asbestos rubber hose structure: The rubber hose is composed of an inner rubber layer, a multi-layer winding layer and an outer rubber layer, wrapped with asbestos cloth, and has a temperature resistance of 300 degrees.
Asbestos hose features: high temperature resistance, 100 degrees water delivery, high pressure resistance, pressure 10kg, 20kg. The burst pressure of the rubber hose is four times that of the working pressure, and it has the characteristics of radiation protection, fire prevention, flame retardant, insulation and anti-aging. Specific specifications and calibers are available. Mainly used in intermediate frequency furnace plants and electric furnace plants.
Introduction of high temperature and high pressure asbestos hose
Asbestos hose is composed of high-density asbestos cloth, rubber outer rubber layer, natural or synthetic fiber reinforcement layer and rubber inner rubber layer. It is suitable for the transportation of cooling water in high temperature areas such as steel and ferroalloy electric furnace smelting. The outer casing of the intermediate frequency electric furnace water cable has the characteristics of high voltage resistance and high insulation.
Asbestos is a commercial term referring to silicate mineral products with high tensile strength, high flexibility, resistance to chemical and thermal corrosion, electrical insulation and spinnability. High temperature and high pressure steel wire wound hoseis a general term for natural fiber silicate mineral resources. Asbestos is composed of fiber bundles, which are composed of long and fine fibers that can be separated from each other. Asbestos has high fire resistance, electrical insulation and thermal insulation. It is an important fire protection, heat insulation and thermal insulation material.
