Raw material costs form the foundation of the price. Fluctuations in the market price of steel directly impact costs. Additionally, the quality and price of anti-corrosion coatings (such as polyethylene or epoxy powder) play a crucial role.
Different anti-corrosion methods vary vastly in terms of materials, processing complexity, and protective performance.
Furthermore, the steel pipe's diameter and wall thickness directly affect the surface area requiring treatment and the amount of material consumed. Generally, larger diameters and thicker walls increase processing difficulty and costs, resulting in a higher price.
When requesting quotes from suppliers, be sure to ask for a detailed breakdown specifying the anti-corrosion process, coating thickness, and applicable standards; this allows for an accurate comparison of price differences. Exercise caution if a quote is significantly lower than prevailing market rates.

Price discrepancies are common in the procurement of anti-corrosion steel pipes. This is mainly because the final price is affected by multiple factors, including the type of anti-corrosion treatment, the base pipe itself, specifications, procurement volume, and market transportation.
The cost of basic seamless pipe and welded pipe substrates is relatively transparent, with limited price differences. The main fluctuation range comes from the materials used for anti-corrosion coatings and the construction process. Even for the same type of corrosion protection, different grades can have vastly different prices.
For example, the price difference between ordinary and reinforced 3PE anti-corrosion coatings (thicker polyethylene layer, stricter requirements) can be more than double. The cost of anti-corrosion coating processing varies depending on the process and materials. Standard anti-corrosion construction includes multiple processes such as pipe pretreatment, rust removal, primer, and topcoat. Reputable manufacturers strictly follow the standards for rust removal, ensuring that the coating thickness meets the requirements and the anti-corrosion service life meets the design life.
Some factories simplify the rust removal process by directly applying anti-corrosion materials. However, the coating has insufficient adhesion, and after only a few years of underground use, the coating peels off, and the pipes quickly rust and leak. Although the purchase price is lower, the pipes are repaired and replaced in advance, which significantly increases the long-term maintenance cost.
When requesting quotations, specify all parameters, including the base pipe material, pipe diameter and wall thickness, type and thickness of the anti-corrosion coating, and applicable standards, to ensure that quotations from different suppliers are based on the same standard.
