Explore our elite portfolio of high-durability marine-grade and industrial gear, engine, and turbine lubrication fluids.
Founded in 2009 and situated in Zibo, Shandong, Shandong Longhai Lubrication Technology Development Co., Ltd. stands as a premier high-tech enterprise. Over the last 15 years, we have built a fully integrated R&D, production, and distribution network. Our ultimate focus is delivering ultra-stable, high-performance lubrication products that cater to the demanding requirements of global marine, petroleum extraction, and heavy-duty transportation industries.
We serve as a vital pillar in the domestic and international energy supply chains. By utilizing advanced synthetic technology, our proprietary brand "Century Longhai" alongside our international strategic partner brand, the British "A Ba" series, addresses the global market’s most rigorous mechanical trials. Our entire range features product and quality liability insurance backed by PICC (People’s Insurance Company of China), assuring operations with risk-mitigated reliance.
Unlocking superior reliability and performance parameters under harsh maritime environments.
Saltwater, high humidity, and severe mist require lubricants with exceptional demulsibility. Longhai's formulations isolate water elements swiftly, creating an impenetrable anti-rust barrier on critical metal gears.
From freezing subsea lines to scorching diesel engine bays, our fluids sustain a stable viscosity index. This mitigates sludge formulation and ensures continuous hydraulic response under sudden temperature swings.
Offshore drilling drives extreme mechanical torque load. Our synthetic gear oil and anti-wear hydraulic oil form robust boundary lubricants that protect gears from micropitting, scuffing, and fatigue.
How Longhai engineering lubricants solve complex wear vectors across offshore drilling, marine logistics, and industrial plant operations.
Offshore exploration and production (E&P) require lubrication systems that can endure some of the most punishing environments on the planet. Heavy seas, high-pressure subsea wells, and non-stop operational cycles leave no room for lubricant breakdown. Shandong Longhai Lubrication Technology Development Co., Ltd. resolves these challenges by introducing high-performance molecular blending designed specifically for deepwater and shelf applications.
Modern offshore drilling rigs depend heavily on hydraulic power to control subsea blowout preventers (BOPs), tensioners, and deck cranes. Our Wholesale Longhai Premium Anti-Wear Hydraulic Oil utilizes premium hydrocracked base oils paired with advanced zinc-free additives. This provides exceptional hydrolytic stability and filterability, preventing filter blockage even in the presence of minor water contamination. It maintains viscosity integrity at extreme ocean floor depths, preventing cavitation and pump wear.
Compressed air systems serve as the lifeline for instrument air and pneumatic tools on offshore platforms. Standard compressor oils struggle against continuous salt-spray exposure, accelerating acid formation and varnish buildup. Our China High-efficiency air compressor oil features enhanced anti-oxidant chemistry that resists thermal cracking. It preserves clean rotors and separators, extending oil drain intervals (ODIs) to over 8,000 operational hours.
With turbine installations moving further offshore, access for maintenance becomes incredibly costly. Gearboxes in these installations suffer from severe wind shear loading and micro-movements, making them prone to micropitting. Our China Longhai Heavy-Duty Gear Oil delivers premium micropitting protection across a wide temperature range, significantly reducing premature gear fatigue. It meets and exceeds major industry specifications including DIN 51517 Part 3, proving its viability under extreme marine wind farm operations.
Merging advanced chemical formulation with high-precision automation systems.
Our intelligent factory features fully automated blending manifolds that monitor raw material flow rate, temperature, and mixing viscosity in real-time. By investing over 5% of annual revenue directly back into R&D, Longhai maintains a highly modern blending setup. The filling production line integrates high-precision volumetric meters to guarantee a filling accuracy of 1‰-2‰, preventing product loss and maintaining stable packaging quality.
Moreover, the integration of these smart systems has boosted overall plant efficiency by 20% to 35%, ensuring we meet large volume procurement requests with minimal lead times.
Spanning 131 acres, our primary production center produces up to 200,000 tons of premium lubricants annually. We serve a broad network across China, providing consistent supply logistics across 139 cities in 29 provinces and autonomous regions. Our international logistics infrastructure supports global bulk shipments, catering to offshore operations in Southeast Asia, the Middle East, and beyond.
To ensure high standards, our laboratory operates high-performance testing instruments, conducting ASTM-compliant checks on viscosity, flashpoint, pour point, CCS, and ICP elements.
Adapting base-oil viscosities and additive chemistry to align with proprietary industrial machinery and regional climates.
We provide full-spectrum customization services for global oil distributors, drilling companies, and marine fleet managers. Our engineering team designs semi-synthetic and fully synthetic formulations tailored to meet API, ACEA, and specific OEM specifications.
We optimize pour points and shear stability indicators to match target environments, from extreme Arctic cold to tropical marine operations.
Our manufacturing lines accommodate trial batches for field tests as well as large-scale bulk containers for international logistics.
Every formulation undergoes rigorous testing to match critical environmental guidelines (such as EPA VGP regulations for biodegradable lubricants).
Evaluating technical parameters, machinery specs, and target applications.
Synthesizing optimal base oils and additive balances in our laboratory.
Running extreme load, corrosion, and oxidation tests on trial samples.
Initiating high-precision automated filling and global shipping logistics.
Providing continuous fluid analysis and optimization recommendations.
Verifying performance and compliance metrics through international audits and strict testing standards.
At Shandong Longhai Lubrication Technology Development Co., Ltd., quality consistency remains our primary focus. We have designed our quality framework to meet key international maritime and heavy industrial operations. Our facility operates under the following certifications:
By blending imported additive packages with high-purity synthetic base stocks, we ensure our oils perform reliably under extreme marine stress, helping operators reduce downtime and extend maintenance intervals.
