Company Introduction Our company (Hebei Goldman Petroleum Machinery Co., Ltd.) is located in Hejian City, a historical city nearby Capital Beijing. Hejian city is nearby the well known Huabei Oilfield ,which propelled the establishment and development of Goldman. We specialize ourselves in researching and production of rock drilling bits, mainly including tricone bits, PDC bits, drag bits, HDD hole opener, roller cutters and related tools like drill pipe,rotary slips, and so on. Our products are mainly used for oil well drilling, gas well drilling, geothermal well drilling, mining, geological survey, water well drilling, HDD pipelines projects and foundation projects. Product Detailed Description 1.Cutting Structure The wear-resistance of the teeth is enhanced with premium tungsten carbide hardfacing on the tooth surfaces for the steel tooth bit.The durability of premium tungsten carbide inserts is improved with new formulas and new techniques for insert bit 2.Gauge Structure Multiple gague protection with gauge trimmers on the heel and gauge inserts on the gauge surface of the cone,tungsten carbide inserts and hardfacing on the shirttail increases gauge holding capacity and bearing life. 3.Bearing Structure High precision journal bearing with two thrust faces,Balls lock the cone.Hardfaced head bearing surface.Cone bearing inlaid with friction-reducing alloy and then silver-plated.Abrasion resistance and seizure of the bearing are improved.and suitable for high rotary speed 4.Seal and Lubrication The advanced metal seal package consists of two metal seals and two elastic energizers.Compressed energizers ensure good contact being kept on two sealing surfaces of metal rings by elastic force,and achieves the bearing seal.In the drilling,metal seals are relatively dynamic,and the energizers are static.This will improve the reliability and durability of bearing seal.The pressure compensator system and advanced grease can greatly increase the lubricating reliability.
