  Since March 2026, the PP pipe material market has experienced a fluctuating upward trend. On March 17, the price of hot water pipe materials in East China reached 9,650 yuan/ton, an increase of 29.97% from the beginning of the month. Affected by geopolitical conflicts, crude oil and propylene prices have continued to rise, providing strong cost support. Meanwhile, the supply of pipe materials has been tight, with petrochemical companies mainly selling directly, and imported resources decreasing, leading to a tight supply situation in the distribution sector, which also provides strong support. Although product prices have lagged in following the upward trend, factories have limited acceptance of high raw material prices. However, as the low-price inventory from earlier is being consumed, the release of immediate demand may provide temporary support to the market. It is expected that PP pipe materials will remain in a strong fluctuating trend before the end of the month.
