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.
