Large diameter steel wire wound hydraulic rubber hose

Structure: the hose is composed of inner rubber layer, steel wire winding layer and outer rubber layer

Gas drainage hole sealer

After adopting the advanced drainage drilling and working face drainage system, the gas emission and cuttings of the drainage drilling increase obviously, which has a good anti-outburst effect, effectively releases the ground stress and gas pressure, and prevents the occurrence of sudden accidents when cutting coal;

Seam water injection hole sealer

Uses: coal water injection, dust reduction, coal pressure reduction, coal cracking, gas discharge, etc.

Seam Reinforcement Packer

It is suitable for plugging holes in coal or rock mass during grouting and water injection.

Water use hole bottom circulating grouting plug

ZF series of hydraulic and pneumatic grouting plug series products are another excellent product developed by our company on the basis of expansion pipes. This series of hydraulic and pneumatic grouting plugs are multi-functional and are widely used in curtain, consolidation, backfilling, chemical grouting, geological exploration water pressure experiments and drilling water plugging of hydropower stations and reservoir projects. The products meet foreign standards.

Steel wire wound drilling hose

Structure: It is composed of inner rubber layer, inner rubber protective layer, middle rubber layer, steel wire winding layer and outer rubber layer.

marine high pressure oil hose

Structure: composed of steel wire winding skeleton layer and internal and external oil-resistant, corrosion-resistant synthetic rubber

Special Hose for Well Control BOP Control Pipeline

Scope of application: GNG high-pressure, fire-resistant and heat-insulating hose assembly is mainly used for hydraulic control of drilling BOP and hydraulic transmission of high-temperature flammable sites in metallurgical industry.

Flexible choke kill manifold

It is suitable for the connection of the relative movement of the drilling platform, semi-submersible drilling ship or drilling ship, and the change of the installation size of the drilling rig, and the transmission of high-pressure media such as oil, gas and mud.

Concrete delivery hose

Structure: made of natural rubber and butadiene rubber inner rubber layer. With high wear resistance. Steel cord or polyester thread is used as the skeleton layer, with small bending radius and light weight. Neoprene is used as the outer protective layer, which is resistant to aging.
