The tanker has good dynamics, economy, safety and reliability. The cross section of the tank is round, oval or rectangular, the tank is equipped with wave-proof board, and the bulkhead can be set according to the requirements of compartment, the bottom of the tank is equipped with output oil pipeline system, the top of the tank is equipped with manhole cover and breathing valve, and the optional sealed filling system can be installed.

What is the composition structure of the tanker?

Tanker trailer is composed of special vehicle chassis and upper part. The basic structure of upper part is composed of tank, piping system, suspension system and other components. According to the requirements of the optional pumping system, insulation system, heating system, closed loading and unloading system, dipstick, tank roof guard, front bridge lifting system, bottom loading system.

• Tank body

Tank material can be selected according to the characteristics of the medium carbon steel, carbon steel lined with plastic, stainless steel, aluminum alloy, etc.. The tank is an airtight loading container. Can be through the bin, but also according to a certain volume divided into a number of independent small bin. The operator can go up to the top of the tank through the escalator at the front or the back of the tank to perform the necessary operations. The upper part of the tank is equipped with manhole and breathing valve, which can be used for top filling and ventilating when discharging material. The manhole can also be used for the operator to enter the tank for maintenance and cleaning, and the breathing valve can keep the pressure balance inside and outside the tank to prevent the pressure inside the tank from being too high or too low and damaging the tank.

• Piping System

The piping system is located at the bottom of the tank and consists of pipes, valves and quick-change couplings. According to the user's demand, it can realize various functions. When discharging, the valve is opened and the liquid is discharged through the discharge hose.

• Suspension system

Steel plate spring suspension and air suspension are optional according to the needs. Usually, carbon steel and stainless steel semi-trailers are equipped with tandem steel plate spring suspension, while aluminum alloy semi-trailers are equipped with air suspension.

• Pumping system

The power source of the pumping system of oil truck and chemical liquid truck is the extractor, and the functions of pumping in and pumping out are realized through the opening and closing of the valve in the pipeline when loading and unloading materials. The structure of this method is simple and easy to operate.

• Thermal insulation system

When the medium shipment temperature requirements are high, in order to prevent the medium from freezing, add insulation layer on the outside of the tank, and then wrap a layer of insulation skin (usually stainless steel, carbon steel or glass fiber reinforced plastic material), through the tightening belt tightening. Insulation layer material is glass fiber, high temperature resistance, good insulation performance; tightening belt tightening, easy maintenance.

• Heating system

When transporting media with high freezing point, a heating system can be added to the tank. Before discharging, the medium is heated by passing steam into the heating pipeline to raise the temperature of the medium and melt it, so as to facilitate discharging. Note that the end with trap is the outlet and the end without trap is the inlet. The maximum allowable steam pressure in the heating pipe is 8 kg/cm².

• Closed Loading and Unloading System

When the liquid medium requires closed loading and unloading, a closed loading and unloading system can be added to the tank. The closed loading and unloading system consists of filling port, oil and gas recovery port (or nitrogen flushing port). When loading and unloading, all need to connect the oil and gas recovery port (or nitrogen flushing port) to maintain the pressure balance in the tank.

• Dipstick usually used for oil tank semi-trailer

The dipstick can be installed on the tanker that needs to use the dipstick as an auxiliary measuring tool. The dipstick is engraved with a height scale and comes with a certificate (height-volume comparison table), which can visually show the volume of the liquid in the tank.

• Tank top guard rail

According to the tank structure design of the tank top lifting guardrail there are two kinds of pneumatic operation and manual operation, pneumatic guardrail operation switch is located near the climbing ladder, manual operation of the guardrail need to raise and lower the guardrail on the top of the tank. When you need to go to the top of the tank to operate, please raise the guardrail first, to ensure the safety of personnel.

• Front Axle Lifting System

Air suspension semi-trailer can be equipped with an optional lifting system to lift the front axle. When the vehicle is empty or partially loaded, the front axle can be lifted, which can effectively reduce fuel consumption and tire wear, thus reducing transportation costs.

• Bottom Loading System

Bottom loading system includes: bottom loading and unloading system, exhaust gas recovery system, control system, spill prevention system, etc.

What is the working principle of oil tanker?

The liquid is loaded into the tank through the top or bottom feeding device and discharged from the tank through the bottom discharging device. When transporting liquids that are easy to solidify, heating pipes can be used to heat them before unloading in order to ensure that the unloading is complete.

What are the considerations for buying tanker trucks？

There are many important considerations like capacity as well as standard and certification requirements to take into account when looking at tank trailers. The most critical factors: what goods you need to consider transporting, which determines what material is chosen for the tank; what shape you want the tank to be, which determines the size of the tank; the material and thickness of the tank, which determines the price and quality of the tank; whether the design of the tanker is safe enough; whether each tanker sold has undergone rigorous inspection, which determines the quality of the tanker; whether the factory has perfect quality control measures.

• Advanced design: the tank and wave guard structure adopts finite element analysis method to establish a full working condition stress analysis model, lightweight design, making the tank lighter with better strength and stiffness; full load-bearing frame, the tank bears most of the load, the whole vehicle weight is lighter, the tank is not easy to deform, more economical and safer.

• Anti-impact structure: The disc-shaped structure of the waveproof plate inside the tank can effectively scatter the shock waves around, reduce the local stress of the plate and protect the tank. According to the medium and road conditions, the waveproof plate adopts the method of sparse and dense arrangement, and the tank is more evenly stressed.

• Leading technology: advanced 13m automatic splicing TIG welding machine, PLC programmable control technology, one package tank forming process: reduce welding seams, high strength, smooth appearance, stable performance of the whole vehicle.

• Safety protection: explosion-proof manhole, emergency cut-off bottom valve (submarine valve), breathing valve, tank top enclosure, sealing harness, oil and gas recovery and a series of safety devices, anti-rollover, anti-collision, fire stop, while improving loading efficiency, safe and environmentally friendly.
