MT98 MINE-USE STEEL WIRE SPIRAL RUBBER HOSE
this mt98 mine-use steel wire spiral rubber hose complies with the mt/t 98-2006 coal industry standard. it is constructed with an oil-resistant synthetic inner tube, multiple layers of copper-plated high-tensile steel wire spiral reinforcement, and a flame-retardant, anti-static, and wear-resistant outer cover. it offers stable pressure bearing capacity and resistance to high-frequency pressure pulses. it can reliably convey media such as mineral hydraulic oil, emulsions, and clean water within an operating temperature range of -40°c to +100°c. designed to withstand harsh underground conditions including moisture, dust, and frequent bending, it is primarily used in hydraulic pipelines for coal mine hydraulic supports, fully mechanized mining units, and underground excavation equipment. it is safe, flame-retardant, anti-static, and provides a long service life.
