In order to withstand the test of ultra-deep wells, ultra-high pressure, high wear drilling conditions, high temperature difference, strong wind and sand and other harsh environments, the R&D team of Litong Technology has deepened the research of basic geological theory, researched new technologies suitable for shale oil and gas exploration and development, and through innovative production Process and material ratio selection, developed and produced LT301F super wear-resistant acidized fracturing hose. The hose uses UHMWPE imported from Germany as the inner layer of the hose, and 4 to 10 layers of super high-flexible steel wire/steel rope are used as the pressure-bearing skeleton material to solve the problems of high pressure, corrosion and wear in the development of ultra-deep oil and gas drilling and production. , Which greatly reduces the replacement frequency of the hose assembly and prolongs the service cycle of the hose. This series of hoses has the following remarkable features:

Application:flexible line using for delivery water-based, oil-based, acid-based and foam fracturing fluids under high pressure in acid, sand and hydraulic fracturing works

Tube:UPE

Reinforcement:4 or 6 layers of high tensile super flexible spiral steel wire or steel cable

Cover:abrasion and weather resistant synthetic rubber

Temperature Range:-20°C~+82°C (-4°F〜+179.6°F)

Standard:API Spec. 7K FSL0 | ABS

Connectors:integral union or integral flange

Full flow: larger diameter and faster flow, helping to increase production efficiently;

Super wear resistance: high pressure conveying emery, the choice of sand fracturing quality, can wear 8000 hours;

Acid and alkali corrosion resistance: UHMWPE lining imported from Germany/Japan can withstand 28% hydrochloric acid, and transport acid-based fracturing fluid without pressure;

Resistant to ultra-high pressure: working pressure up to 20000Psi (about 138MPa), burst pressure up to 40000Psi (about 276MPa), high fracturing efficiency, ensuring safe operation.
