  • NSSJ Series Wear-Resistant Expansion Joints Read More

    NSSJ Series Wear-Resistant Expansion Joints

    The SSJ sleeve expansion joint has a compact structure that accommodates axial displacement between connected pipelines. The source describes movement compensation, high pressure resistance, multiple connection options, reliable operation and straightforward installation and maintenance.
  • PH Series Slag Discharge Check Valves Read More

    PH Series Slag Discharge Check Valves

    This check valve is intended for mineral slurry, mortar, wastewater and ash/slag mixtures in mining, metallurgy, power, chemical and wastewater systems, at pressures not exceeding 6.4 MPa and operating temperatures up to 100°C.
  • NL Series Wear-Resistant Throttle Valves Read More

    NL Series Wear-Resistant Throttle Valves

    The NL series wear-resistant throttle valve was developed for severe valve wear in hydraulic ash removal systems. It provides continuous flow adjustment in two-phase pipelines used in thermal power plant ash removal, mining and other industries.
  • GHZ44H Series Dry Ash Gate Valves Read More

    GHZ44H Series Dry Ash Gate Valves

    This dry ash gate valve is described by the source as a patented design with flexible operation and long service life. It serves as an on/off device in pneumatic conveying systems for dry ash, fly ash and cement, including thermal power plant applications.
  • NPZ Wear-Resistant Slag Discharge Gate Valves Read More

    NPZ Wear-Resistant Slag Discharge Gate Valves

    The NPZ series wear-resistant slag discharge gate valve is designed for mineral-processing and tailings slurry pipelines in ferrous and nonferrous mining, power-plant hydraulic ash removal and slag-water systems, at nominal pressures up to 6.4 MPa and temperatures up to 120°C. The source specifies JC/T2306-2024. Cast basalt or other wear-resistant materials line the inlet and outlet passages. A tapered outlet, slag-guide groove and cast basalt lining at erosion-prone areas help discharge slag. The streamlined base matches the pipeline bore to reduce accumulation and wear, particularly in service with high ash/slag content or larger particles.

frequently ask question
Factory workshop and basalt cast stone production photo 1
Yes, we are a group company of factories and export offices.
Please provide us with detailed requirements regarding product size, organization, quantity, and other special requirements, and our staff will quickly offer you the most favorable price.
Of course, please leave us your contact information and phone number. The samples are free, but the shipping fee should be credited to your account.
Of course, we will customize sizes for your different projects.
Usually our port is Qingdao Port, but it depends on the situation. Some special products will be exported from the ports closest to their quarries and factories, allowing them to offer you more competitive prices.
Reasonable prices and guaranteed quality, as we always have a professional quality control team of 8-10 people. We accept third-party inspection before shipment.
Typical applications include coal chutes and hoppers, ash and slag handling, mineral-slurry pipelines and selected chemical-service surfaces. Suitability depends on abrasion, impact, temperature, chemical exposure and the complete lining system.
A basalt liner is brittle and should not be assumed to carry the pressure or structural loads of a complete pipeline. Review it together with the outer pipe, filling layer, supports and connections in the approved assembly design.
Use the equipment geometry and a dimensioned layout drawing. Flat, curved, tapered or other shaped pieces may be appropriate at different locations. Confirm the actual dimensions, joints, edges and installation arrangement before ordering.
No single lining is suitable for every duty. Cast basalt requires a specific review where there is severe impact, rapid temperature change or chemical exposure. The joints, bedding and supporting structure must also be compatible with the operating conditions.
Service life depends on the conveyed material, flow, impact, temperature, installation and maintenance. A result reported for another plant or supplier should not be treated as a guarantee. Confirm the agreed supply specification and inspection plan for your project.
