Geossum

Geossum is a subsidence‑prevention component designed for geothermal borehole systems. It is installed as a recycling water pipe that maintains continuous water looping during borehole subsidence events. The product also incorporates a filler placed between the inner casing and excavation hole to raise the heat‑conductivity rate. Additionally, the design secures the grouting zone at the lowest part of the borehole, eliminating gaps even when the casing joint deviates.

The pipe is typically fabricated from high‑density polyethylene (HDPE), a material recognised for chemical resistance and long‑term durability in underground conditions. Standard industry dimensions include an outer diameter of 110 mm and a wall thickness of 6 mm, delivering a pressure rating of about 10 bar. Operating temperatures normally range from - 20 °C to 80 °C, aligning with ISO 4437 specifications for polyethylene pipe. These typical parameters enable the pipe to sustain the thermal cycles of geothermal loops while providing reliable heat transfer.

Geossum is used by geothermal plant developers, civil‑engineering contractors and utility firms that require stable loop operation in subsiding terrains. The component is supplied in bundled coils of ten metres and is packed for bulk shipment, with incoterms and payment conditions to be agreed directly with Vision Value Consulting Co., Ltd. As the listing does not disclose exact minimum order quantities, lead‑time or certification status, interested buyers should confirm these details with the supplier before placing an order.
