On 13 and 14 October, via the enterprise standard information public service platform, Dalipal issued two enterprise standards successively, "Technical Specifications for High-Strength and High-Toughness Petroleum Casing and Tubing, Part I, Deep Well and Ultra-Deep Well Casing (Standard No.: Q/DLP 102-2022)" and "High Airtight Special Thread for Petroleum Casing DLP-T4 Dimensional Parameters and Performance Specifications (Standard No.: Q/DLP 101-2022)".

Dalipal has been committed to the research and development of non-API tubing and casing products and application technologies. The products under the two standards are products with independent intellectual property rights developed to meet the needs of drilling and exploitation of oil and gas resources in harsh environments. The two standards bring together a large amount of research and development, production and application data, which can be used as the basis for customer application material selection and product acceptance. Dalipal will continue to provide customers with better products and services through product research and development and standardization.
