| Product introduction | ||||||||||||
| Pipes for petroleum mechanical processing are necessary materials for petroleum exploration equipment, drilling equipment, mechanical oil production equipment, petroleum drilling and production equipment and accessories, and complete sets of oil and gas gathering and transportation. Heavy Metal Company has successfully independently developed 55-135 ksi steel pipes for petroleum machinery processing, which have good strength and toughness matching, uniform wall thickness and excellent processability. | ||||||||||||
| Uses of pipes for petroleum machinery processing; | Pipes for petroleum machinery processing can be used to be processed into accessories for drilling and completion tools, and used for oil service products such as downhole power drilling tools, suspension isolation systems and wellhead system devices. | |||||||||||
