Petroleum Casing Products of Tianjin Great Victory Petroleum Equipment Co.

Petroleum casing produced by Tianjin Great Victory Petroleum Equipment Co., Ltd. is an essential component in oil extraction and drilling projects. Its main function is to support the wellbore, prevent it from collapsing and provide a stable passage for oil and gas extraction. Our oil casing is widely used in onshore and offshore oil extraction projects, and has won a good reputation in domestic and international markets for its excellent quality and wide range of applications.

Complete specifications

We offer a wide range of petroleum casing from 41/2 inches to 20 inches, covering various steel grades such as J55, K55, N80, L80, P110, 13Cr, etc. These different specifications can meet the needs of different wells. These different sizes meet the requirements of different well depths, pressures and geological conditions. Whether it's a shallow or deep well, low or high pressure environment, our casing provides reliable support and protection.

High Quality Standards

All of our casing is manufactured in strict accordance with API Spec 5CT standards and is certified to ISO 9001 quality management system. Every step of the process, from raw material procurement to finished product inspection, is strictly controlled to ensure the high strength, toughness, corrosion resistance and sealing performance of the casing. We use advanced production equipment, such as CNC lathes, automatic flaw detectors and CNC hydraulic testing machines, to ensure the machining precision and quality consistency of each casing.

Fast Delivery

With sufficient inventory and efficient production processes, we can respond quickly to customer needs, typically delivering within 715 days. This not only shortens the customer's waiting time, but also ensures the smooth running of the project. We understand that time is money in oil exploration projects, so we are committed to providing our customers with the most efficient service possible.
