Product Introduction

It is mainly used in rock drilling and crushing, anchoring and drilling geothermal air conditioning holes, water well drilling, etc. The pipe body is made of materials produced by well-known large-scale iron and steel enterprises in China. The two ends of the pipe body adopt internal thickening technology, and are tempered after friction welding. The drill pipe joint is subjected to quenching and tempering heat treatment after rough machining. The surface phosphating and nitriding treatment after finishing effectively prevent the failure probability of sticking, breaking and cracking of outer diameter expansion, easy to disassemble, all use precision CNC lathes with customized forming knives for thread processing, all threads are equipped with thread gauges in line with international standards, so the production of drill pipe performance is stable, reliable, greatly lengthened the life cycle.

The company has many advanced CNC lathes, friction welding machines, pipe end upsetting and thickening machines, and complete production equipment. It has established a quality management system in accordance with the ISO9001. Professional system management personnel have conducted many trainings for all employees. The quality management system Perfect and effective operation. From the signing of the order to the inspection and delivery of the finished product, we use a variety of identification methods such as labeling, lettering, painting and recording all the data to ensure the traceability of the product. Equipped with a variety of specifications of thread testing gauges, pitch testing instruments, taper testing equipment, flaw detection equipment, hardness testing equipment, with the required physical and chemical testing equipment, can be a full range of mechanical performance testing of drilling tools as required.
With sincere cooperation, reliable quality and high-quality service as the enterprise concept, we should improve the level of self-management, adjust the market layout, enhance the scientific and technological content of products, solve the needs of customers, and make customers feel at ease in buying and using.
