Hunan Wangkun Pipe Industry Co., Ltd. Successfully Establishes CNAS-Accredited Laboratory

In 2025, Hunan Wangkun Pipe Industry Co., Ltd. achieved significant progress in the testing of stainless steel pipes and fittings. Through industry-academia-research collaboration with Central South University and Xiangtan University, the company successfully established and officially launched a CNAS-accredited laboratory. This milestone signifies that Wangkun Pipe Industry has attained national-level standards in product testing capabilities and quality assurance systems.
The laboratory has obtained accreditation from the China National Accreditation Service for Conformity Assessment (CNAS). Its testing capabilities cover multiple critical performance indicators for stainless steel pipes and fittings, providing authoritative and reliable technical support for product R&D, production, and quality control.

Laboratory Equipment
The laboratory is equipped with specialized apparatus for conducting bending tests, angle bending tests, and pressure-sealing inspections on stainless steel pipes and fittings. Bending and angle bending tests simulate complex stress conditions encountered during actual installation and use. By testing under varying bending angles and radii, these procedures comprehensively evaluate the products' plastic deformation capacity, crack resistance, and overall structural stability, ensuring safety and reliability in real-world engineering applications.

Pipe Polishing Machine
For pressure resistance and sealing performance testing, the laboratory conducts rigorous water-filled pressure tests to detect leaks under specified pressure conditions. This verifies the products' pressure strength and sealing capabilities, ensuring compliance with relevant national standards and engineering requirements.
A representative from Wangkun Pipe Industry stated that the establishment and operation of the CNAS-accredited laboratory represent a significant achievement in the company's ongoing commitment to technological innovation and quality enhancement. Moving forward, the company will leverage its strengths in industry-academia-research collaboration to continuously advance testing capabilities and R&D capacity. This will enable the provision of safer, more reliable, and higher-quality stainless steel pipe and fitting products to customers, thereby contributing to the high-quality development of the industry.
