Projects
Valve supply and project cases in oil & gas, refining, power and chemical applications
Tailings Slurry Knife Gate Valves for a Chilean Copper Concentrator
The project supplied wear-resistant knife gate valves, large-diameter butterfly valves and wear-resistant gate valves for the tailings transport and return water systems of a copper concentrator in South America, for shutoff and isolation of high-density slurry and return water lines.
Fluorine-Lined Valve Package for an East China Chlor-Alkali Plant
The project supplied a complete package of lined butterfly valves, lined ball valves and corrosion-resistant globe valves to an integrated chlor-alkali plant in East China, for shutoff and control on brine, hydrochloric acid, sodium hypochlorite and other highly corrosive lines.
Butterfly and Check Valve Batch Supply for a North African Municipal Wastewater Plant
The project supplied wafer butterfly valves, dual-plate check valves and flanged gate valves in batches for the expansion of a municipal wastewater treatment plant in North Africa, for aeration, return sludge and effluent lines.
Large-Diameter Butterfly Valve Retrofit for a District Heating Network in North China
The project replaced large-diameter butterfly valves and ball valves on the primary network (main lines DN800–DN1400) of a city district heating system in northern China, solving internal leakage and excessive operating torque.
API 6D Ball Valve Delivery for a Middle East Refinery Project
The project covered the packaged delivery of API 6D trunnion-mounted ball valves and associated valves for a refinery expansion in the Middle East, across critical points including tank farm isolation, process line isolation and truck and tanker loading arms.
Corrosive Media Valve Replacement at a Southeast Asian Fine Chemical Park
The project replaced valves that had failed in batches on sulfuric acid, acetic acid and organic solvent lines at a fine chemical park in Southeast Asia, including fully lined ball valves, lined butterfly valves and stainless steel globe valves.
Butterfly Valve Batch Supply for an Indonesian Water Treatment Plant
The project supplied large-diameter butterfly valves and resilient-seated gate valves in batches for a new water treatment plant in Indonesia, covering raw water, clean water networks and booster pump stations.
High-Pressure Gate Valve Retrofit at a Central Asian Power Plant
The project implemented high-pressure gate valve and control valve retrofits on the main steam and feedwater systems of a Central Asian power plant, replacing aged main steam gate valves and adding feedwater pump minimum-flow control valves.
High-Pressure Water Injection Valve Supply for a Middle East Offshore Platform
The project supplied API 6D trunnion-mounted ball valves, high-pressure globe valves and check valves for the high-pressure seawater injection system of a Middle East offshore platform, for injection pump outlets, distribution manifolds and wellhead injection lines.
Blast Furnace Gas Butterfly Valve Replacement at a Southeast Asian Steel Plant
The project replaced large-diameter butterfly valves and gate valves on the blast furnace gas (BFG) system and hot blast lines of an integrated steel plant in Southeast Asia, solving gas cross-flow and high energy consumption caused by internal leakage.
High-Pressure Hydrogen Valve Selection and Technical Consulting for an East China Refueling Station
The project provided high-pressure hydrogen valve selection and technical consulting for a hydrogen refueling station in East China, covering high-pressure ball valves, globe valves and check valves in the 35 MPa/70 MPa refueling process.
Gathering Pipeline Valve Replacement in the Russian-Speaking Region
The project supplied valve replacements and spare parts to a gathering station in the Russian-speaking region, replacing failed ball valves and gate valves to restore station shutoff and sealing performance.
