Gas Drainage Inflatable Packer For Coal Seam
The Gas Drainage Inflatable Packer for Coal Seam is a composite unit built around high‑pressure expansion hoses, a central steel pipe, a sliding sealing coupling and a pressure‑injection coupling. It is offered with a diameter selectable between 60 mm and 150 mm and a working pressure range of 1 MPa to 6 MPa, both of which can be customised to site requirements. Fluid can be injected at a rate of 5‑8 tons per hour, while the expansion index varies from 60 % to 100 % depending on the pressure applied. The packer is designed to inject water into coal seams, draw out gas and reduce dust‑related hazards.
The hose assembly is fabricated from a special rubber compound that resists abrasion and chemical attack typical of coal‑seam environments. The central pipe is forged steel, providing the rigidity needed for high‑pressure expansion, and the sliding sealing coupling ensures a leak‑free interface during operation. Such construction follows industry practice for underground gas‑drainage tools, where durability and pressure containment are critical. Typical temperature operating limits for similar rubber‑based packers are - 20 °C to +120 °C, which matches the expected underground conditions.
The packer is suitable for water injection to lower gas content, dust suppression and moisture control in coal‑seam mining projects. Primary buyers include mining contractors, ventilation engineers and safety managers responsible for underground gas management. The supplier can customise diameter, pressure rating and coupling design, but exact minimum order quantities and shipping terms must be confirmed directly. Buyers should request FOB or CIF quotations and verify certification status before finalising the contract.

Sourcing Gas Drainage Inflatable Packer For Coal Seam from Hebei Huayu Special Rubber Co., Ltd. - China Import Guide
Before ordering, confirm the exact diameter, pressure rating and coupling type required for your borehole. Request engineering drawings and, if possible, a third‑party test report that validates the rubber hose’s tensile strength and the steel pipe’s pressure tolerance. Clarify whether the supplier can provide a material safety data sheet for the rubber compound.
Discuss logistics early: ask the supplier which Incoterms they can offer, typically FOB or CIF, and verify the lead time for custom‑fabricated units. Because the supplier’s response rate is currently low, allow extra time for quotation preparation and arrange a written agreement outlining delivery milestones. Payment terms should be negotiated in line with standard industry practice, such as a 30 % deposit and balance against shipping documents.
Plan for quality assurance on arrival. Arrange an independent inspection to check dimensions, pressure rating stamps and the condition of the sliding sealing coupling. Verify that the packaging - a steel‑frame crate - is intact and that all components are listed on the packing slip. Retain all test certificates and material data for future compliance audits.
