Under the background of global economic integration, the pace of overseas expansion of China's manufacturing industry is accelerating, and many excellent enterprises have gone abroad to participate in international competition and cooperation. Recently, Shijiazhuang Weilida Prospecting Machinery Co., Ltd., as a member of the domestic drill rod manufacturing industry, was also invited to participate in the International Mining and Construction Equipment Exhibition held in Manila, the capital of the Philippines. This exhibition is not only a comprehensive display of the company's strength, but also an important step for it to actively expand overseas markets and seek international cooperation opportunities.
At the exhibition, Shijiazhuang Weilida Prospecting Machinery Co., Ltd. carefully arranged the booth and displayed its latest series of high-performance drill rod products. These products have attracted the attention of many domestic and foreign exhibitors and buyers with their excellent quality, advanced technology and ability to adapt to a variety of complex geological conditions. The company representatives introduced the characteristics, advantages and successful cases of the products in detail, and conducted in-depth exchanges and discussions with partners from all over the world. Many visitors highly appreciated the professional strength and innovative spirit of Weilida drill pipe in China and expressed their intention to further cooperate. This exhibition not only further enhanced the visibility and influence of Shijiazhuang Weilida Mining Machinery Co., Ltd. in the international market, but also laid a solid foundation for its overseas market development and deepening international cooperation. In the future, the company will continue to uphold an open and cooperative attitude, actively participate in international competition, and contribute more to promote the overseas development of China's manufacturing industry.

During drilling you do indeed spin a length of ferrous pipe so it can become magnetized - a little. Your 5lb hammer may become a little bit attracted to it, certainly not repelled and this is due to a natural phenomena you get when rotating steel in a magnetic field (the Geo magnetic field in this case).
Modern drill pipe is made from the welding of at least three separate pieces: box tool joint, pin tool joint, and the tube. The green tubes are received by the drill pipe manufacturer from the steel mill. The ends of the tubes are then upset to increase the cross-sectional area of the ends.
Because it bends easily, heavy weight drill pipe simplifies directional control and minimizes connection fatigue problems that are common in high-angle or horizontal drilling. For extended reach and horizontal wells, high-strength heavy weight drill pipe is often used high in the hole to apply weight on the bit.
Drill pipe weight calculators estimate the mass of hollow drill pipe by computing its steel volume (outer area minus inner area) and multiplying by steel density.
This is the last one.
