Hc110 Q125 11th Edition Oil Well Tubing Special Purpose Casing C90 90ss L80 1 - China

price: 830.00 Dollar US$

1 - HC110 Oil Casing Q125, 10th Edition, Oil Well Tubing, Special-Purpose Casing, C90, 90SS, L80-1 Oil casing is an essential type of pipe in the oil and natural gas drilling industry.

The HC110 Oil Casing Q125, 10th Edition, as a high-end product, has become a leader in the field of special-purpose oil well casing due to its outstanding performance and wide range of applications.

Product Features:

- The HC110 Oil Casing Q125 is manufactured using advanced processes and complies with the API 5CT standard.

It features high strength, high toughness, and corrosion resistance.

- The chemical composition is strictly proportioned, with carbon content ≤0.35%, manganese content ≤1.35%, nickel content ≤0.99%, chromium content ≤1.50%, and molybdenum content ≤0.85%.

These alloy elements ensure excellent performance in harsh oil drilling environments.

- In terms of mechanical properties, the yield strength ranges from 862 to 1034 MPa, the tensile strength is ≥931 MPa, and the impact toughness is ≥60 J in the transverse direction and ≥100 J in the longitudinal direction at 0°C, enabling it to withstand complex stress conditions.

Application Fields:

- This product is widely used in the oil and natural gas drilling industry as a casing for oil wells.

It can withstand complex underground pressures and geological conditions, ensuring the safety and stability of oil wells.

Additionally, it can be used to manufacture tubing, casing couplings, and other petroleum drilling tools and equipment, contributing to efficient extraction operations.

Product Advantages:

- The manufacturing process of the HC110 Oil Casing Q125, 10th Edition, strictly controls quality.

From raw material procurement to finished product inspection, every step is rigorously tested to ensure reliability and stability.

Moreover, we offer customized services to meet the individual needs of different customers.

Casing Connection Types:

1 - LTC (Long Thread Connector): Long round thread.

Although LTC threads are similar in shape to STC threads and can connect, they are generally not recommended for connection due to differences in the torque they can withstand.

2 - STC (Stub (Short) Thread Connector): Short round thread.

STC and LTC threads are both API standard threads, differing only in thread length.

The longer one is LTC, and the shorter one is STC.

For pipes with an outer diameter of 4-1/2", a thread length exceeding 3 inches is typically LTC, while less than 3 inches is STC.

3 - BTC (Buttress Thread Coupling): Buttress thread.

Available Casing Sizes: 4-1/2'', 5'', 5-1/2'', 6-5/8'', 7'', 7-5/8'', 8-5/8'', 9-5/8'', 10-3/4'', 11-3/4'', 13-3/8'', 16'', 18-5/8'', 20''.

Steel Grades: J55, K55, N80-1, N80Q, L80-1, P110, L80-3CR, 9CR, 13CR, P110-13CR (Super 13CR), 28CR.

Connection Types: Short round thread (STC), long round thread (LTC), buttress thread (BTC), and various high gas-tightness special threads.

Production Process: Hot rolling.

Product Usage: For oil well drilling.

Packaging: Steel bands/steel frames, or as per customer requirements.

Annual Supply Capacity: 300, 000 tons.

Quality Standards: We strictly adhere to the API Spec 5CT standard and the ISO 9001 international quality management system.

We possess manufacturing equipment, including CNC lathes, CNC threaders, automatic flaw detectors, CNC hydrostatic testers, automatic marking machines, automatic painting and marking machines, 16-ton cranes, ultrasonic thickness gauges, and automatic feeding systems.

Market Reach: While meeting domestic market demands, we serve numerous enterprises with high-quality products and have established long-term supplier relationships with countries and regions such as Saudi Arabia, the UAE, Sudan, Kuwait, and Turkey.

Corporate Philosophy:

Mission: Integrity, Pragmatism, Mutual Benefit, Win-Win.
