API Oil Casing Pipe Price

According to the latest market data (as of June 2025), the price of API oil casing pipe is affected by factors such as material, specification, steel grade, and production process, and the price range is relatively large. The following is a summary of the main price information:

1. Prices of oil casing of different steel grades

Steel grade	Price (yuan/ton)	Main features	Applicable scenarios
J55	3,960~4,500	Basic steel grade, medium strength	Shallow wells, low-pressure wells
N80	5,600~6,500	High strength, general corrosion resistance	Medium-deep wells
L80	6,810~7,500	Corrosion resistance (including Cr, Mo)	Environment containing hydrogen sulfide (H₂S)
P110	4,620~8,800	Ultra-high strength, high pressure resistance	Deep wells, ultra-deep wells
TP125V	8,800+	Special alloy, anti-collapse	Extremely high-pressure wells

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.
