Engineered for extreme operating environments. Browse our top featured wholesale solutions designed for industrial efficiency and long-term equipment protection.
Shandong Longhai Lubrication Technology Development Co., Ltd. was established in 2009. Headquartered in the key industrial hub of Zibo, Shandong, we operate as a high-tech enterprise integrating R&D, production, and sales. With over 15 years of industry specialization, we have built a comprehensive industrial chain system focused on supplying top-tier lubrication solutions globally.
Through our proprietary brand "Century Longhai" and international strategic collaboration brands like the British "A Ba" series, we produce premium diesel engine oils, gasoline engine oils, gear oils, hydraulic transmission oils, anti-wear hydraulic oils, motorcycle oils, special engineering machinery oils, and industry-grade turbine engine oils. Backed by quality insurance from PICC China People's Insurance Company, our products guarantee absolute reliability and security.
How our advanced chemical research shapes the next generation of turbine engine lubrication.
Modern gas turbines operate at extreme temperatures, predisposing Group I and Group II base oils to thermal degradation and varnish formation. Our future-focused R&D team leverages Group III and Group IV (PAO) synthetic formulations coupled with specialized ashless dispersant additive systems. This chemistry solubilizes breakdown precursors, ensuring clean hydraulic control valves, reducing friction losses, and avoiding unscheduled outages.
Through rigorous testing under ASTM D943 TOST (Turbine Oil Oxidation Stability Test), our advanced turbine oils achieve oxidation life markers exceeding 10,000 hours. The incorporation of synergetic phenolic and aminic antioxidant packages provides a sacrificial mechanism against oxidation, maintaining low acid number (TAN) and excellent viscosity index stability under heavy thermal loads.
Aligning with global ESG (Environmental, Social, and Governance) expectations, our laboratory is actively optimizing rapidly biodegradable synthetic ester turbine oils. Designed for hydroelectric dams and sensitive marine industrial complexes, these lubricants match the heavy-load performance of conventional mineral oils while minimizing ecological footprint upon contact with soils and water systems.
Operational robustness is critical to securing global supply networks. Longhai's Zibo manufacturing plant covers 131 acres, designed under strict automation principles. By investing over 5% of annual revenue directly into engineering R&D, we have converted our facilities to support smart manufacturing and fast lead times.
Our automatic blending plant incorporates PLC control systems to accurately meter chemical raw materials and base stocks, eliminating operator variation. The state-of-the-art automatic filling lines leverage high-precision volumetric meters ensuring a weight deviation limit of just 1‰ to 2‰. Furthermore, our line efficiency enhancements have increased overall filling speeds by 20% to 35%, ensuring high output to meet emergency global orders without backlogs.
Tailoring premium turbine formulations to fit specific power generation and heavy industry demands.
Combined Cycle Power Plants (CCPP) subject turbine fluids to severe thermal gradients. Our formulation offers superior thermal-oxidative control, minimizing sludge buildup and maintaining system pressure. Excellent air release properties protect bearings from cavitation damage, while rapid water separation prevents hydrolysis, safeguarding structural integrity.
Large industrial air compressors, process gas compressors, and high-speed turbochargers require extremely thin, highly stable fluid films. Our turbine engine oils provide exceptional shear stability and anti-wear protection, reducing frictional heat generation and component wear profiles while maintaining steady oil flow rates over high RPM runs.
Hydro plants present challenges concerning high ambient moisture and potential water ingress. Our turbine formulations prevent rust and corrosion by actively repelling water molecules. Demulsibility curves ensure that water separating from the oil can be easily drained from sump systems, preventing emulsion formation and bearing surface pitting.
We convert unique equipment specifications into optimized fluid formulations through our complete manufacturing flow.
Longhai Technology offers end-to-end customization services, tailoring fully synthetic and semi-synthetic lubricant recipes to meet international standards such as API, ACEA, DIN, and ISO. Whether you require specific viscometrics, tailored additive treatments, or a target budget structure, our engineering team works alongside your technical staff to formulate optimal products.
Our operational framework supports quick development steps: from demand analysis, laboratory design, and physical testing, to pilot trial runs. By leveraging high filling speeds, automatic line changeovers, and in-house packaging and label designers, we help global distributors launch private label product lines with confidence and speed.
Adhering to strict international benchmarks and supplying documented verification for import markets.
Managing chemical imports requires navigating complex regulatory standards. Shandong Longhai is certified under ISO 9001:2015 Quality Management, ISO 14001 Environmental Management, and ISO 18001 Occupational Health Management systems. Additionally, our high-quality formulations have achieved official Mercedes-Benz automatic transmission certifications, reinforcing our engineering credibility.
For international buyers, we supply complete regulatory documentation including GHS-compliant Safety Data Sheets (SDS), certificates of analysis (COA) for every manufacturing batch, and custom clearance documents. Our international strategic alliance with British "A Ba" products ensures our chemicals comply with REACH regulations in Europe, and EPA requirements in the Americas, facilitating smooth port clearance and supply continuity.
Procurement departments look for more than a chemical manufacturer—they require a partner that helps reduce Total Cost of Ownership (TCO). Unstable lubricants lead to high filtration costs, component wear, and lost downtime, which quickly wipe out any short-term savings from buying cheap raw materials.
Longhai minimizes procurement risks by using premium base oils and additives from top-tier global suppliers, ensuring stable quality batch-after-batch. Our advanced logistics capabilities, combined with our strategic location near Qingdao Port, reduce transit costs and lead times. This allows us to keep lead times short and offer flexible minimum order quantities (MOQs) to protect your working capital.
