In the field of industrial applications, standardized seamless steel pipes often fail to meet the stringent demands of specific working conditions. With 21 years of technical expertise in the industry, Changzhou Tenjan Steel Tube Co., Ltd. breaks through standard limitations to provide customers with comprehensive customized seamless steel pipe solutions. We understand that each application scenario has its unique characteristics, and only tailor-made products can ensure optimal performance and service life.

In-Depth Needs Analysis: A Design Philosophy Based on Working Conditions

Customized services begin with a deep understanding of the customer’s working conditions. Our technical team conducts on-site visits to thoroughly analyze key parameters such as the operating environment, load characteristics, and medium properties of the seamless steel pipes. In high-temperature and high-pressure environments, we use chromium-molybdenum alloy steel and employ special heat treatment processes to enhance creep resistance. For corrosive media, we adjust the chemical composition to improve corrosion resistance.

For different application scenarios, we develop tailored technical solutions: petroleum cracking units require high-temperature strength and resistance to hydrogen damage; hydraulic systems demand high dimensional accuracy and surface quality; automotive components need excellent fatigue performance and lightweight characteristics. This working-condition-based design philosophy ensures that every seamless steel pipe meets the specific usage requirements.

Material Innovation: Chemical Composition Design Beyond Standards

We have established strategic partnerships with renowned steel mills such as Baosteel and Shagang to customize steel billets with special chemical compositions according to customer needs. By precisely controlling the content of alloying elements, optimizing the ratios of basic elements like C, Si, and Mn, and adjusting the addition of alloying elements such as Cr, Mo, and Ni, we enable the seamless steel pipes to achieve specific performance characteristics.

For example, to enhance low-temperature toughness, we appropriately increase the Ni content; to improve high-temperature strength, we optimize the Cr-Mo ratio; and to enhance weldability, we strictly control the carbon equivalent. This material-level innovation allows our seamless steel pipes to truly "exceed standards" in performance.

Process Breakthroughs: Customized Production Technologies

Adopting special rolling and heat treatment processes is key to achieving performance customization. We have developed multi-stage controlled rolling technology, which refines grain size and improves overall mechanical properties by precisely controlling rolling temperature and deformation. Innovative heat treatment processes, including differential temperature heat treatment and protective atmosphere heat treatment, ensure the seamless steel pipes achieve the desired microstructure.

Quality Assurance: Fully Controlled Customization Process

From raw material procurement to finished product delivery, we implement full-process quality control. Each batch of customized seamless steel pipes has an independent quality file documenting all process parameters and inspection data. We are equipped with advanced testing equipment, including metallographic testing, eddy current flaw detectors, and ultrasonic flaw detectors, to ensure the products meet customized requirements.

Particularly noteworthy is our non-destructive testing capability: multi-channel ultrasonic flaw detectors are used to inspect internal defects, and eddy current testing instruments are employed to check surface quality. These testing methods provide strong support for ensuring the reliability of customized seamless steel pipes.

Technical Support: A Service Model of Full Process Accompaniment

We provide end-to-end technical services, from needs analysis to usage guidance. Our team of professional engineers is always available to offer technical consultations, help optimize design solutions, and address issues during usage. We maintain technical files for customers and conduct regular follow-ups on usage conditions to continuously improve product quality.
