Technical Specifications Upgrade the Industry | Jiangsu Zhide Pipe Industry Participates in GB/T 13401-2025
Technical Specifications Upgrade the IndustryJiangsu Zhide Pipe Industry Participates in GB/T 13401-2025GB/T 13401-2025, *Steel Buttwelding Piping Fittings—Technical Specification*, has officially come into force. Replacing GB/T 13401-2017, the new standard provides a more comprehensive technical basis for the manufacture, inspection and delivery of steel buttwelding pipe fittings.A complete technical framework for pipe fittingsSteel buttwelding fittings are widely used in petroleum, petrochemical, natural gas, power generation, shipbuilding, marine engineering and industrial piping systems. Although compact in size, these fittings perform essential functions such as connection, sealing, direction change, diameter reduction and flow distribution.GB/T 13401-2025 specifies technical requirements covering ordering information, materials, manufacturing, heat treatment, inspection and testing, weld repair, surface protection and packaging, as well as product quality certificates.This means that product quality is evaluated not only by final dimensions, but also by material traceability, process control, inspection completeness and documentation. The standard provides a clearer technical language for designers, manufacturers, inspection bodies and end users.Industry experience contributes to standard developmentAccording to publicly available information from the National Standards Information Public Service Platform, Jiangsu Zhide Pipe Industry Co., Ltd. is listed among the drafting organizations for GB/T 13401-2025, while Zhang Xinbao is listed as one of the principal drafters.Participation in national standard development allows practical manufacturing experience, quality-control methods and engineering feedback to contribute to the standardization process. It also encourages companies to further improve their research, manufacturing, inspection and quality-management systems.Jiangsu Zhide Pipe Industry focuses on industrial piping accessories and pays close attention to material selection, forming and manufacturing processes, heat treatment, non-destructive testing, dimensional control and quality documentation. Through continuous improvement, the company provides reliable piping connection products and services for energy, chemical processing, equipment manufacturing and other industries.Building quality through standardsStandards provide a common technical language for the manufacturing industry and an important reference for quality management. The implementation of GB/T 13401-2025 will further promote improvements in material control, process stability, inspection capability and product consistency across the steel buttwelding fittings industry.Looking ahead, Jiangsu Zhide Pipe Industry will continue to use standards as a guide and quality as its foundation. By strengthening its product development, manufacturing, testing and service capabilities, the company aims to deliver safer, more stable and more professional piping connection solutions.From a single fitting to a complete technical specification, and from one weld to a safe and reliable industrial pipeline, standards turn manufacturing expertise into lasting value.Quality begins with standards. Excellence is built through expertise.Official Standard Information：National Standards Information Public Service Platform

Standards Lead the Way, Connections Shape the Future | Jiangsu Zhide Pipe Industry Participates in GB/T 12459-2025
Standards Lead the Way, Connections Shape the FutureJiangsu Zhide Pipe Industry Participates in GB/T 12459-2025GB/T 12459-2025, *Steel Buttwelding Piping Fittings—Types and Parameters*, has officially come into force. As an important foundational standard for steel buttwelding pipe fittings, it replaces GB/T 12459-2017 and provides updated technical guidance for the selection, design and manufacture of related products.The standard covers key fitting types including elbows, tees, crosses, reducers, caps and stub ends. It specifies requirements for fitting types and designations, pressure design, dimensions, surface contours, end bevels, tolerances, marking and product quality certificates.A clearer technical basis for industrial pipingSteel buttwelding fittings are widely used in petroleum, petrochemical, natural gas, power generation, shipbuilding, marine engineering and general industrial piping systems. They perform essential functions such as connecting, sealing, changing direction, reducing diameter and dividing flow.GB/T 12459-2025 applies to seamless and welded steel buttwelding fittings within the DN8–DN3400 range, providing a more systematic technical basis for engineering design, product selection, manufacturing, inspection and acceptance.The update is more than a change in standard number. It reflects the continued improvement of domestic manufacturing capabilities, the practical needs of industrial projects and the effort to align Chinese standards with international engineering practices.Industry participation strengthens the standardAccording to publicly available information from the National Standards Information Public Service Platform, Jiangsu Zhide Pipe Industry Co., Ltd. is listed among the drafting organizations for GB/T 12459-2025, while Zhang Xinbao is listed as one of the principal drafters.Participation in national standard development brings practical manufacturing experience, quality-control practices and feedback from real engineering applications into the standardization process. It also reflects the responsibility of manufacturing companies to support the long-term development of the industry.With its focus on industrial piping accessories, Jiangsu Zhide Pipe Industry continues to pay close attention to materials, forming processes, dimensional accuracy, product consistency and inspection requirements. The company’s involvement in standardization is both a contribution to the industry and an opportunity to further strengthen its own technical and quality systems.Building a more reliable future through standardsStandards provide a common technical language for designers, manufacturers, inspectors and end users. They also serve as an important reference for quality management and product traceability.Looking ahead, Jiangsu Zhide Pipe Industry will continue to focus on engineering safety and customer needs, improve its product development, manufacturing, testing and service capabilities, and provide reliable and traceable piping connection solutions for energy, chemical processing, equipment manufacturing and other industrial applications.From a single fitting to an entire standard, and from one connection to a safe and reliable industrial pipeline, standards help turn manufacturing expertise into lasting value.Standards lead the way. Connections shape the future.Official Standard Information：National Standards Information Public Service Platform
