Drill collar up to nearly the number of drill collars manufacturers branches of production planning support, import and export of products up to 719, of which nearly 300 HWDP products in addition to conventional spiral heavy weight drill pipe also increase the drill pipe, drill collar large size contracts with nearly 200 Products involved in 34 varieties, tube specifications ranging from 127-255.
 In the production process, there are more than 290 branch collars on quality products with special requirements. Qualified tensile strength, impact strength required to achieve a minimum of 80 and 85 joules, -20 ℃ low temperature impact work to ensure that more than 30 joules. Technical requirements relate ZT-JT5, NS-1 standard, the product performance requirements, but also meet the requirements of full supervision. This is the drill collar branch this year received the largest number of high-performance products, contracts, and this month is engaged full production tasks to complete difficult.
 In order to meet the technical requirements to ensure smooth delivery of goods according to the contract period, collars branch accurate to determine the time each process node, and strict checking of the production node completion last week in the weekly production of a regular meeting, if you find problems in time to do Well adjustments to ensure the orderly production. Upon completion of the node tasks simultaneously, and strictly control product quality, earnestly HWDP Hardbanding heat affected zone and the public, magnetic particle inspection at the female threaded screw, for heavier pipe body ultrasonic testing in strict accordance with ZT-JT5 ∮1.5 equivalent standard of conduct required to ensure the accuracy of the product. For the next processing of large sample machines and equipment can not meet the demand, drilling jars manufacturers the branch dispatcher actively coordinating with the Brothers production.
Drill Collar branch with a high sense of responsibility to organize the various stages of production, combined with their own actual development plan targeted organizational measures, reasonable arrangements for production capacity, the focus on efforts to achieve guaranteed, there is a breakthrough on the difficulties in the weak link there make up, around the whole value chain system of lean management, lean management will penetrate into each step of production, to ensure the successful completion of production tasks this month.
