2026 carat tube market, the latest quotation trend list

Fundamental Analysis of Supply and Demand in Carat Tube Market in 2026

In 2026, projects such as domestic municipal pipe network transformation, rain and sewage diversion projects, and sponge city construction will continue to advance. As a mainstream product in the field of buried wastewater discharge, carat pipes will maintain a steady growth of about 6% in the overall market demand due to their strong corrosion resistance, long service life, and convenient construction. On the supply side, with the improvement of the industry's environmental protection access threshold, small and medium-sized production capacity will gradually be cleared, and the production capacity release rhythm of the top production enterprises will basically match the growth rate of demand. The market supply and demand are in a tight balance throughout the year. The price fluctuation of upstream HDPE raw materials has become the core variable affecting the market.

The latest quotation trend of carat tubes in 2026

From the industry quotation statistics for the beginning of 2026, the quotation of conventional caliber carat tubes has risen by 3% -5% as a whole compared with the end of 2025. Among them, the quotation range of DN300 specification products with ring stiffness level 4 is 120-150 yuan/meter, and the quotation range of products with the same specification with ring stiffness level 8 is 210-240 yuan/meter. Products with large caliber DN1200 and above are quoted 15% -20% higher than conventional caliber due to high production energy consumption and high process difficulty. Looking at the trend, the first quarter was driven by the rise in the price of upstream HDPE raw materials, and the quotation completed the first round of increases. In the second quarter, it entered the peak construction season, and the quotation was likely to maintain a slight increase under the concentrated release of demand. In the second half of the year, with the release of raw material production capacity and the price drop, the price of carat tubes is expected to be stable and moderate, and the price fluctuation range for the whole year is controlled within 8%. It should be noted that the current market quotation difference is mostly related to whether it is equipped with sealing rubber rings and whether it includes transportation costs. When purchasing, it is necessary

Construction reference of carat tube selection under market fluctuation

Faced with price fluctuations throughout the year, the purchaser can reasonably select the type according to the engineering needs to reduce costs: products with ring stiffness level 8 and above can be selected for sewage projects in municipal main roads and heavy-duty areas, and products with ring stiffness level 4 can be selected for non-heavy-duty scenarios such as community branch pipe networks and landscaping drainage to meet the demand. There is no need to blindly pursue high parameters and cause cost waste. The construction process needs to be flattened in advance to avoid sharp stones scratching the pipe wall. The interface is operated in strict accordance with the welding specifications of heat shrinkable sleeves to ensure airtightness and reduce later maintenance costs. For long-term large-scale procurement, the engineering party can sign a periodic pricing agreement with the supplier to lock in the procurement cost and avoid the risk of raw material price fluctuations.
