Product Introduction of Oil Casing by Tianjin Grand Victory Petroleum Equipment Co.,Ltd

The oil casing produced byTianjin Grand Victory Petroleum Equipment Co.,Ltd is an essential component in petroleum exploitation and drilling projects. Its primary function is to support the wellbore, prevent wellbore collapse, and provide a stable conduit for the extraction of oil and gas. Our oil casing is widely used in both onshore and offshore petroleum extraction projects, and it has earned a good reputation in the domestic and international markets for its excellent quality and extensive application range.

Full Range of Specifications 

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

HighQuality Standards 

All our casings are manufactured strictly in accordance with the API Spec 5CT standard and have passed the ISO 9001 quality management system certification. Every step, from raw material procurement to finished product inspection, is strictly controlled to ensure the casing's high strength, toughness, corrosion resistance, and sealing performance. We use advanced production equipment, such as CNC lathes, automatic flaw detectors, and CNC hydrostatic testing machines, to ensure the processing accuracy and quality stability of each casing.

Fast Delivery 

With ample stock and an efficient production process, we can quickly respond to customer needs and usually complete delivery within 715 days. This not only reduces the waiting time for customers but also effectively ensures the smooth progress of projects. We are well aware that time is money in petroleum exploitation projects, so we are committed to providing the most efficient service to our customers.

Customization Services 

In addition to standard specifications and steel grades, we also offer customization services. According to customers' special requirements, we can produce nonstandard specifications of casing or process special threads and connection forms on the casing. No matter what your needs are, we can provide you with tailormade solutions.
