Remanufacturing of Well-chosen Used Kelly Bars
Well-chosen
Court - auctioned kelly bars are a main source of Shenwei Foundation's premium - selected used ones. They're attached to court - auctioned rotary drilling rigs. In the past 2 yrs, due to the decrease in piling projects, some new rigs had short construction time, causing overdue mortgages. Drilling rig manufacturers reclaimed rigs (court - auctioned rigs) legally, and their kelly bars are court - auctioned kelly bars.
These kelly bars have merits: short time since leaving the factory, few working hrs, good condition, high newness; made and accepted per main - machine factory quality reqs as originally bought by rig factories. Also, Shenwei foundation's pros evaluate and select them.
Strict Overhaul
Kelly bars are disassembled and shot - blasted. Inspectors check thoroughly, record well, and reject non - compliant ones. Overhaul stds are based on Shenwei foundation's new kelly bar mfg ones. Used kelly bars are overhauled per enterprise stds to optimize performance and reliability. After overhaul, they're repainted for rust prevention. Records are made from inspection to warehousing, with quality files for use and service.
Product Information Management
Each kelly bar set has a unique product number. Each product is photographed to ensure "what you see is what you get". A set of product desc. docs with pics, texts, and vids of details is available via customer service. Quality files with inspection and overhaul records ensure after - sales.
