When buying Vacuum Sewage Truck<\/a><\/strong>, many buyers focus on the chassis brand, vacuum pump model, and tank capacity, but are easy to ignore an important factor that directly affects vehicle life-the tank material and plate thickness. In fact, the long-term stability of a Vacuum Sewage Truck depends largely on whether the tank is sufficiently robust, corrosion resistant and capable of withstanding long periods of negative pressure operation.<\/p>\n\n\n\n

Why is tank thickness so important?<\/strong><\/strong><\/p>\n\n\n\n

When the Vacuum Sewage Truck is operating, the vacuum pump continues to create a negative pressure environment inside the tank. If the thickness of the steel plate is not enough, it is easy to deform and bump after long-term use, and even the phenomenon of “sucking and shrinking the tank body” often mentioned in the industry occurs.<\/p>\n\n\n\n

In order to reduce costs, some low price models in the market often use thin steel plates or unstable materials. Although the purchase price seems to be lower, in the case of frequent suction operations, the containment capacity of the tank is insufficient and the later maintenance costs are higher.<\/p>\n\n\n\n

In contrast, our Vacuum Sewage Truck<\/a><\/strong> is manufactured from high quality Q235 carbon steel, and the thickness of conventional tank can reach 5mm or 6mm, which can effectively improve the overall structural strength and ensure the stability of long-term high-load operation.<\/p>\n\n\n\n

Corrosion protection shall also not be ignored<\/strong><\/strong><\/p>\n\n\n\n

In addition to thickness, corrosion protection is an important factor in the life of the Vacuum Sewage Truck.<\/p>\n\n\n\n

Sewage, sludge and septic tank waste are usually corrosive. If the tank body is not properly protected, it is easy to have rust, perforation and other problems inside.<\/p>\n\n\n\n

Our tanks are treated with professional anti-corrosion process, and the internal anti-corrosion coating can be added according to the customer’s requirements, effectively reducing the loss caused by corrosion and prolonging the service life of the equipment. This is particularly important for customers in hot, wet or coastal areas.<\/p>\n\n\n\n

High-strength steel and advantages of automatic welding<\/strong><\/strong><\/p>\n\n\n\n

A quality Vacuum Sewage Truck<\/strong> <\/a>requires not only thick steel plates, but also reliable manufacturing processes.<\/p>\n\n\n\n

We use high strength Q235 steel and are equipped with automatic welding production line to ensure each weld joint is even and firm. Compared with traditional manual welding, automatic welding can effectively reduce solder skips, cold solder and other problems, and improve the overall tightness and pressure bearing capacity of the tank body.<\/p>\n\n\n\n

This means lower failure rates and longer service life for customers who have long been engaged in municipal decontamination, industrial waste liquid transportation, or septic tank cleaning operations.<\/p>\n\n\n\n

Choose the durable Vacuum Sewage Truck to really save money<\/strong><\/strong><\/p>\n\n\n\n

The purchase of Vacuum Sewage Truck should not be based solely on price, but rather on long-term operating costs. High-strength Q235 carbon steel tank with a thickness of 5mm or 6mm can effectively avoid deformation, corrosion and cracking of the tank with professional anti-corrosion treatment and automatic welding process.<\/p>\n\n\n\n

For customers who want to have a long-term stable operation, a high-quality Vacuum Sewage Truck<\/a><\/strong> can not only improve operation efficiency, but also reduce maintenance expenditures and create a higher return on investment.<\/p>\n\n\n\n

FAQ<\/strong><\/p>\n\n\n\n

Q1: What is the general thickness of Vacuum Sewage Truck tank?<\/p>\n\n\n\n

The typical configuration is 5mm or 6mm, with thicker plates for high strength service.<\/p>\n\n\n\n

Q2: Why do some suction trucks have their tanks aspirated?<\/p>\n\n\n\n

The main reasons are that the steel plate is too thin, the material strength is insufficient or the internal structure is not reasonably designed.<\/p>\n\n\n\n

Q3: Is Q235 carbon steel suitable for manufacturing tank body of sewage truck?<\/p>\n\n\n\n

Yes, the Q235 has good strength, welding performance and economical efficiency and is the mainstream choice in the industry.<\/p>\n\n\n\n

Q4: Is corrosion protection necessary?<\/p>\n\n\n\n

Very necessary to effectively reduce wastewater corrosion and extend tank life.<\/p>\n\n\n\n

Q5: What are the advantages of automated welding?<\/p>\n\n\n\n

The welds are more uniform and firm, which can improve the tightness and overall structural strength of the tank.<\/p>\n\n\n\n
