All the supply records for most of the severe drilling environments indicate that NIPPON STEEL is the leader in tubular technologies. Field development where it was impossible to drill yesterday becomes a reality with NIPPON STEEL tubular products today. Customer satisfaction and reliability are the keywords for our product development.  \nOur product line covers almost all applications from carbon steel to Ni based alloy steel with conventional API connections or advanced sealing mechanisms such as VAM premium connections. NIPPON STEEL has the widest material grades for Casing & Tubing. And as a result of continuous R&D efforts, you can find more “fit for purpose” products in this brochure.  \nPrinciples of NIPPON STEEL SEAMLESS CASING & TUBING  \nQuality  \nQuality is the most fundamental element of our Casing & Tubing business. We understand that quality leads to product reliability, which in turn leads to customer trust and that in the end, quality is the basis of our reputation. We will continue to be dedicated to maintaining and improving our quality standard.  \nTechnology  \nThe more severe the drilling conditions, the greater our customers’ needs for cutting edge products. We understand that customers rely on the quality of our products when they drill in harsh conditions, and we are proud of our No. 1 technical position. We will continue to work through our R&D activities to develop high-end products for the future.  \nCustomer Satisfaction  \nOur goal is to be more than just a superior product supplier. We intend to also be a superior solutions provider for our tubular products customers. We place importance not just on managing material sales, but also on “before” and “after service”. Customer satisfaction drives our const","cbCaicq3TqLoLwpU","https://ap.wps.com/l/cbCaicq3TqLoLwpU","pdf",4377407,18,"English","# INTRODUCTION\n# FACILITIES AND LOCATIONS\n# MANUFACTURING SITES\n# MANUFACTURING PROCESS OF SEAMLESS STEEL TUBES AND PIPES\n# MATERIAL SELECTION GUIDELINES\n# AVAILABLE GRADES\n# MECHANICAL PROPERTIES","[{\"question\":\"What are the key principles behind NIPPON STEEL’s seamless casing and tubing business?\",\"answer\":\"The brochure emphasizes quality as the foundation for reliability, technology to meet severe drilling needs, and customer satisfaction through solution-oriented sales and before/after service.\"},{\"question\":\"What facilities and locations does NIPPON STEEL list for manufacturing seamless products?\",\"answer\":\"It highlights main areas including Kansai Works Amagasaki and Kansai Works Wakayama, along with affiliated-company facilities and centers such as Amagasaki Research and Development Center and Research \\u0026 Engineering Center (Futtsu).\"},{\"question\":\"How does the document describe the manufacturing process of seamless steel tubes and pipes?\",\"answer\":\"It provides an overview of carbon and alloy steel making and shaping routes, including processes such as the Mannesmann process, extrusion and forging, and plant types for medium-size and small-size seamless production.\"}]","SEAMLESS CASING & TUBING - Introduction | PDF",45]
