  • Description

Our Hetai company specializes in producing casing pipes for oil drilling, which are primarily used to support the wellbore, prevent collapse and leakage, and can also serve as a conduit and protect the oil layer during drilling. Our products are made of high-performance epoxy fiberglass.

The following are the features of our casing pipes:

1. High strength: made of high-performance epoxy fiberglass, the casing has excellent bearing and tensile properties.

2. Corrosion resistance: the casing can resist the erosion of corrosive substances such as acids and alkalis, ensuring durability and longevity of the product.

3. Stability: strict quality control and inspection ensure the stable physical and chemical properties of the casing, meeting international standards.

4. Excellent design: the size and structure of the casing are adjusted according to different drilling environments and reservoir conditions to ensure optimal performance during drilling operations.


Our high-performance casing pipes are suitable for various oil and gas exploration and production operations. We can provide casing pipes of different specifications and sizes according to customer requirements, as well as corresponding technical support and services to meet customer needs.
