Drill pipe used to connect the surface equipment of the drilling rig to the grinding or drilling equipment, it is the steel pipe with thread ends, also making the connection of the bottom hole equipment of the drilling. Drill pipe normally divided into kelly, drill pipe and heavy drill pipe. Steel Drill Pipes comes in a variety of sizes, strengths, and wall thicknesses, but is typically 27 to 32 feet in length (Range 2). Longer lengths, up to 45 feet, exist (Range 3). Drill collar is the main section of the lower drill tool, it is worked at the bottom of the drill string. The thickness of the drill collar is larger, and also the greater gravity and rigidity. To improve the tripping work, processing elevator grooves and slip grooves on the outer surface of the inner thread of the drill collar would be a good choice. Spiral drill collars, integral drill collars. and non-magnetic drill collars are the main drill collars in the market.The packaging method for steel pipes involves cleaning, grouping, wrapping, bundling, securing, labeling, palletizing (if necessary), containerization, stowing, sealing, transportation, and unpacking. Different kinds of steel pipes and fittings with different packing methods. This comprehensive process ensures that the steel pipes shipping and arrive at their destination in optimal condition, ready for their intended use.
