DESEINOR was established in 2008 and has over 17 years of experience in the tank truck parts and fuel station equipment industry. We specialize in the production of manhole covers, bottom loading valves, overfill prevention valves, API adapters, composite hoses, couplings, and other key tank truck components. We have built long-term partnerships with clients across global markets.

Our tank truck equipment and parts are certified to meet major international standards, including CE, ADR (EU), UL (U.S.), IEP ATEX explosion-proof, and CCS (China Classification Society). In addition, we operate under the ISO 9001 Quality Management System to ensure safety and reliability across all products.

Yes. We implement comprehensive quality control procedures, including material inspection, dimensional checks, pressure testing, sealing performance tests, and fatigue resistance evaluations. All products come with a 1 to 2-year warranty, during which we offer free replacement or repair for any quality-related issues.

Most standard parts are kept in stock and can be shipped immediately. For customized products, the production lead time is usually 7-20 days, depending on the order quantity. We work with reliable logistics partners to ensure on-time delivery for both domestic and international orders.

We offer 24-hour technical support, including usage guidance, installation training, and remote technical consultation. All DESEINOR products come with full after-sales service, including repairs, replacements, and technical upgrades, to ensure peace of mind for our customers.

Before transport or unloading, a static grounding reel must be connected to the ground to prevent static buildup. A vapor recovery system should be installed between the tanker and storage tank to reduce flammable vapor accumulation. Flame arresters and pressure vacuum vents must be inspected regularly to ensure proper explosion-proof functionality.

Cold temperatures may cause seals to harden and valves to seize, affecting pumping efficiency. It’s important to use low-temperature-resistant materials, apply insulation layers or electric trace heating systems, and regularly drain residual liquids from pipelines to prevent freezing.

Conduct regular inspections of manhole covers, sealing gaskets, and breather valves to prevent leakage and structural damage from pressure differentials. Use overfill protection system to avoid overfilling and minimize the risk of fuel spills during loading.

Tank materials must be corrosion-resistant and pressure-rated to meet hazardous goods transport standards. Valves and fittings should come with leak-tightness and pressure resistance test reports. All parts must be compatible with the tanker’s specifications and connection interfaces.

Components must use stainless steel or specialized alloys to resist chemical corrosion. High-performance gaskets ensure tight sealing with no leakage. Explosion-proof and anti-static systems such as grounding reels and flame arresters are required. For volatile or viscous liquids, chemical-grade pumps must be selected for reliable operation.

Our fuel dispensers are equipped with high-precision flow meters, ensuring fuel delivery accuracy stays well within the regulated error range. Regular calibration can be performed to maintain long-term stability and compliance.

Regularly inspect pipelines for leaks or blockages. Clean the filtration system to prevent impurities from affecting fuel flow. Calibrate the flow meters periodically to ensure accurate measurement, and ensure all electrical systems are operating properly to eliminate safety risks caused by wiring faults.

Choose the appropriate tank capacity based on fueling demand. Select from single-nozzle, dual-nozzle, or multi-nozzle dispensers, depending on fuel types such as gasoline, diesel, or aviation kerosene. Consider whether the unit supports smart payment systems, including IC cards, QR code scanning, or card swiping.

Yes, we provide tailor-made LPG filling station solutions, including customizable tank sizes, dispenser configurations, and smart management systems to meet different operational requirements.

The site must be level, well-ventilated, and located away from open flames. Local safety permits, such as gas operation licenses and fire inspection approvals, must be obtained (we provide technical documentation support). Both the hydrocarbon pump and electronic filling scale require 380V and 220V power supply for operation.
