What Can Go Wrong When Buying A Water Tank Only Based On Price?

What can go wrong when buying a water tank only based on price?

Cheap water tank shrinks in all three categories

When choosing to purchase stainless steel water tanks, some manufacturers offer prices that are so low that they can make people fascinated. However, behind these are usually the reduction in quality of plate thickness, material, and welds. The steel plate was reduced from the original 1.0 mm to 0.8 mm, the 304 material was replaced with 201, and full welding was converted into spot welding. Through these methods, the quotation can be reduced without spending any money.

In less than two years, the water tank began to leak. If you buy a water tank based on the price, what problems are likely to arise? The cost of repair is much higher than the small price difference saved in the first place. When the plate becomes thinner, the load-bearing capacity is reduced, the box becomes prone to deformation and bulging, and the weak welds directly lead to leakage. These problems are not visible when purchasing, but they are all hidden dangers when using.

Material replacement is the biggest trick

The price difference between 304 stainless steel and 201 stainless steel is significant. For water tanks of the same size, the cost will vary by a certain distance due to different materials. Some manufacturers, in order to lower the quotation, replace 304 with 201. The surface looks similar, but the corrosion resistance is quite different. When the chloride ions in the incoming water are slightly high, the 201 material will easily become rusty and perforated.

For regular manufacturers, when making a quotation , the material grade will be clearly marked, and a third-party testing report can also be provided. When purchasing, be sure to read the material certificate clearly, and do not just listen to verbal promises . Although the price of 304 material is relatively more expensive, it can achieve stable use for ten years. If it is spread out every year, it is almost negligible.

The board is not thick enough and the box is deformed

The standards set by the country have clear requirements for the thickness of water tank plates. However, those cheap water tanks often cannot meet such standards. If the board is too shallow, its pressure-bearing capacity will be insufficient. When the water tank is filled with water, the box will be easily deformed. In severe cases, bulging will occur, and even cracking may occur. If the thickness of the plate is insufficient, it will not only affect the service life, but may also cause safety accidents.

When purchasing, the manufacturer needs to clearly indicate the thickness of each steel plate on the quotation. When it is accepted, spot checks can also be carried out with the help of a thickness gauge. Those standardized manufacturers will not antagonize you because of the issue of plate thickness. The reason is that everything they manufacture is made of real materials.

Spot welding replaces full welding with great hidden dangers

Whether the water tank will leak is directly determined by the quality of the weld. Full welding is welded along the entire weld, and its firmness is the highest. Spot welding is welded at intervals. Although it is fast, it is not strong enough. Some low-price water tanks use spot welding instead of full welding. Once the time becomes longer, the weld will crack and leakage will be inevitable.

When reviewing the quality of welds, it is necessary to consider whether the welding is uniform and whether there are missing welds or weak welds. Those standardized manufacturers will take the lead in clarifying the welding process and will also promise a warranty period. Welding technology is the core indicator of water tank quality, and there is absolutely no room for ambiguity.

Procurement logic is changing

As early as ten years ago, the water tank market was competing to see whose quotation was the lowest. At this time, customers holding orders with prices indicated only looked at the total price value, while manufacturers desperately tried to reduce production costs. This cost-cutting behavior repeatedly reduces the thickness of the steel plate and the quality level of the welds. In the end, all that remains are hidden dangers. In recent years, as relevant standards and rules have been updated and replaced, and the requirements for sampling inspections of water quality have become more stringent, the way to gain advantages through competition through low prices has become increasingly narrow and difficult.

Nowadays, when many production plants invite bids, the quotation needs to clearly indicate the thickness of the plate, the grade of the material used, and the number of years of quality assurance, and there must also be a test report issued by a third party. The price is no longer the only indicator to be considered, but must be placed in the material condition, production process, and after-sales service before comparison and inspection. Such a change is a rare and beneficial thing for those manufacturers that produce genuine products.

Correct purchasing order is important

If you want to buy a water tank, why is the processing cost of stainless steel so high? You must first determine the material and specifications, then compare the workmanship and warranty, and finally look at the price. The water tank is not a one-time investment, and maintenance costs must be calculated. It needs to be cleaned and disinfected every six months. The maintenance cost of a fifty-ton water tank in ten years is not a small amount, and this part must be included in the general ledger.

The price is quoted by a professional manufacturer, and the plate thickness, material and accessories details will be clearly listed. Every penny has its source. After purchasing, you will know why it is expensive and whether it is worth it. At this time, I know that the water tank is not a fast-moving consumer product. Once installed, it will be used for more than ten years. What you buy is not only a container, but also a safety guarantee. So when buying a water tank, will you first pay attention to its price, or will you pay attention to its material at the first moment? Please share your personal experience in the comment area.
