About Us
Dellok Yonghui company In order to survive with quality, enterprises regard reputation as life, established a perfect after-sales service system, equipped with complete production and testing equipment, and a number of professional and technical personnel with pioneering and innovative spirit, so as to ensure the excellent quality of our products.Oil casing is a kind of large diameter pipe to hold oil and gas well walls or holes. Casing is inserted into the well hole and secured with cement to prevent the well from separating the rock and collapsing, and to keep the drilling mud circulating to facilitate drilling and production.The failure loss of oil pipe is huge, and its safety, reliability and service life are of great importance to the oil industry.
