2. Key factors affecting prices
Material and steel grade:
Ordinary carbon steel (J55) is the cheapest, and alloy steel (such as L80-3Cr) is doubled in price.
Special anti-corrosion coatings are more expensive, such as polyethylene lining and ultra-high molecular weight polyethylene casing.
Specifications (outer diameter/wall thickness):
Small diameters (such as 114.3mm) are cheaper, and large diameters (such as 508mm) are more expensive.
Thick-walled pipes (such as 16mm) are 30%~50% more expensive than thin-walled pipes (such as 6mm).
Production process:
Seamless casing (such as API 5CT standard) is 20%~40% more expensive than
ERW welded pipes.
The price of cold-drawn precision pipes can reach more than 9,000 yuan/ton.
Market supply and demand:
For example, overseas export orders surged in Q1 2025, pushing up the prices of some high-end casings.
3. Recent price trends
Ordinary steel grade (J55/N80):
The average price in June 2025 is 4,000~6,000 yuan/ton, up 5%~10% from the beginning of the year.
High-end steel grade (P110/TP125V):
Affected by the growing demand for deep well mining, prices remain high (8,000+ yuan/ton).
Purchasing suggestions:
1. Bulk purchase: large orders are negotiable.
2. Pay attention to steel mill policies: manufacturers' regular price adjustment announcements.
3. Select materials according to demand: J55 for shallow wells and L80-3Cr for sulfur-containing oil and gas wells.
4. Select suppliers: regions with strong price competitiveness.
It is recommended to refer to real-time market quotations (such as "MySteel Network") and combine supplier negotiations to optimize costs.
