    Shanghai BoTeng Welding Consumables Co.,Ltd.

    Shanghai Boteng Welding Conaumables Co., Ltd, located in Baoshan Industrial Zone, Shanghai, is a high-tech enterprise specializing in the research and development, production, sales and related technical services of hardbanding wires specifically for oil pipes such as drill strings. It has strong research and development capabilities of welding materials, advanced production and testing equipment, and perfect quality management system.The company has passed ISO9001 quality management system,ISO14001 environment management system and ISO45001 occupational health and safety management system certification. Furthermore, BoTn series hardbanding products have also passed NS-1 certification.  
    The pioneering application  of the "balanced wear resistance and friction reduction design" philosophy has driven the research and development of flux-cored welding wires for drill pipe wear bands. After more than two decades of R&D, we have introduced the BoTn1000, BoTn3000, and BoTn5000 series—high-performance, wear-resistant, and friction-reducing flux-cored welding wires for drill pipe wear bands. These products are primarily used for drill pipes, heavy-weight drill pipes, drill collars, stabilizers, shock absorbers, sucker rod couplings, and sucker rods in oil drilling equipment. Additionally, they have broad applications in other industries, including mining, chemicals, and power generation.
    The BoTn series have undergone rigorous evaluation  by several authoritative third-party institutions, both domestically and internationally, including Mohr Engineering Division (USA), Bodycote Materials Inc. (USA), Howard & Associates International Inc. (USA), and Xi’an Maurer Petroleum Engineering Laboratory (China). The results of these tests have confirmed the exceptional performance of the products.
    Moreover, the BoTn series hardbanding wires have been recognized as a Shanghai High-Tech Achievement Transformation Project, and have received non-repayable grants from the Ministry of Science and Technology, the Ministry of Finance, and the Science and Technology Commission of Shanghai Municipality (STCSM),  which actively support and promote their wider adoption.
