MT98 mining wire coiled rubber hose is used for mining hydraulic support, petroleum mining, mining equipment, construction machinery and equipment, hoisting and conveying equipment, ships, metallurgy, agricultural machinery, plastic machinery and various machinery automation and intelligent hydraulic In the transmission system, the inner layer of the tube body is made of gray-black acid and alkali-resistant styrene-butadiene rubber. To ensure low bending, the reinforcing layer is made of super-soft high-strength steel wire woven with one or two layers, and the surface layer is gray-black acid and alkali resistant, Weather-resistant, abrasion-resistant styrene-butadiene rubber for continuous operation in environments ranging from -40°C to 100°C (-40°F to 212°F).

The outer layer of the hydraulic oil hose wall thickness is oil-resistant rubber, and the middle is (2 to 4 layers) cross-braided stainless steel wire or coiled stainless steel wire. Poor quality rubber hose will show: the thickness of the rubber wall is uneven; the stainless steel wire is too tight or too loose or the number of layers of wire rope is too small; the poor sealing performance of the surface glue causes the stainless steel wire to rust; the internal glue sealing performance is poor and the high pressure oil Random access to the stainless steel wire layer; lack of adhesion between the surface layer and the stainless steel wire layer. LT301 API 7K series products — high-pressure mortar plastic hoses are used to transport water-based mortar, oil-based mud, etc. after oil drilling/cementing/workover operations.

It can effectively bear the sliding friction force generated by the transported substances. Most of the reinforcement layers are made of 2–6 layers of stainless steel wire, with the international API 7K qualification certificate, which greatly meets the needs of the Chinese market. Improper application Under the premise that the quality has an inspection port, if the application is not appropriate, the service life of the rubber hose will be greatly reduced. In practice, most of the damage to high-pressure hoses is caused by improper application. Shocked by constant and violent work pressure. The cracking of the high-pressure hose is generally not caused by excessive static pressure, but is related to the strong ability and frequency of pressure shock. During the course of construction machinery and equipment, the sudden rise or decrease of steam pressure in the oil pipeline will repeatedly occur, and then it will cause continuous pressure impact on the oil pipeline, resulting in aggravated damage to the skeleton seal everywhere, and the rubber hose will appear bubbles and ruptures.

And the detachment of the joint leaks the view. Therefore, during the operation process, the valve seat cannot be rotated with excessive force, and it must be dangerous in the filling process of the dangerous goods tanker. It is forbidden to fill the liquid ammonia storage tank, liquid chlorine, compressed natural gas, lng natural gas and other vaporization hazards with plastic hoses. thing. Therefore, our company provides various types of stainless steel wire to improve plastic hoses, industrial hoses, UPE/PTFE rubber-plastic composite multi-purpose plastic hoses, oil drilling plastic hoses, chemical hoses and other sealing gasket products.

This product is mainly used in construction machinery and equipment, oil drilling, coal mining, and other fields. Shale oil and gas refers to the fossil energy contained in the source rock formations with extremely low porosity and coverage, including organic diabase and igneous rocks developed in shale and laminae, including shale porosity and crevices. Crude oil, which also includes fossil fuels in dense igneous or clastic interlayers in shale formations, is developed and designed using gas wells and hydraulic fracturing techniques similar to shale gas.
