ASME A355 Heat Exchanger Seamless Pipe
Product description:
The seamless pipe of heat exchanger is a type of steel pipe formed by punching through round steel, with no welds on the surface. According to the production method, seamless steel pipes are divided into hot-rolled seamless steel pipes, cold-rolled seamless steel pipes, cold-drawn seamless steel pipes, and hot-expanded seamless steel pipes. Seamless steel pipes are classified into two types based on their cross-sectional shape: circular and special-shaped.
ASME A355 Heat exchanger seamless pipe is a high-grade alloy steel tube specifically designed for heat exchangers, superheaters, reheaters, and boilers operating in high-pressure and high-temperature environments. Manufactured in accordance with ASME SA355 / ASTM A355, this pipe provides superior mechanical strength, thermal stability, and corrosion resistance, ensuring safe and efficient heat transfer performance in the power generation, petrochemical, and refining industries.

Product Overview
ASME A355 Seamless Heat Exchanger Pipes are made from ferritic alloy steels that contain chromium and molybdenum as strengthening and corrosion-resistant elements. They are designed to withstand high internal pressures and fluctuating temperatures while maintaining excellent dimensional stability and low deformation rates.
The combination of high tensile strength, oxidation resistance, and superior thermal conductivity makes A355 seamless pipes ideal for power plants, refineries, and chemical processing plants, where both efficiency and safety are vital.
Manufacturing Process
To meet the stringent requirements of ASME and ASTM standards, A355 Heat Exchanger Seamless Pipes are produced through advanced metallurgical and finishing techniques:
- Raw Material Selection: Alloy steel billets containing Cr and Mo are carefully selected for purity and consistency.
- Hot Piercing and Rolling: Billets are pierced and rolled into hollow tubes with precise wall thickness.
- Cold Drawing: Further processed for enhanced dimensional accuracy and smooth internal surfaces.
- Heat Treatment: Normalizing, tempering, or quenching to refine the microstructure and enhance toughness.
- Non-Destructive Testing: Ultrasonic, eddy current, hydrostatic, and dimensional tests ensure integrity.
- Surface Finishing: Pickling or shot-blasting for clean, corrosion-resistant surfaces suitable for heat exchange applications.
- Each pipe is supplied with full Mill Test Certificates (MTC) according to EN 10204 3.1/3.2, confirming compliance with ASME A355, ASTM A355, and ASME B36.10M standards.
Applications:
The application range of seamless steel pipes is very wide, including structures, fluid transportation, low and medium pressure boilers, high-pressure boilers, fertilizer equipment, petroleum cracking, geological drilling, diamond core drilling, petroleum drilling, ships, automotive half shaft sleeves, diesel engines, etc. Seamless steel pipes will be used to avoid leakage and other problems, ensure the effectiveness of use, and improve material utilization. It can be seen that the application of seamless steel pipes mainly reflects three major fields. One is in the field of construction, which can be used for underground pipeline transportation, including extracting groundwater during construction. The second one is in the field of machining, which can be used for mechanical processing, bearing sleeves, etc. The third field is electrical, including gas pipelines and fluid pipelines for hydroelectric power generation.
ASME A355 Heat exchanger seamless pipes are widely used in industrial systems that demand high-temperature operation and reliability:
- Heat exchangers for chemical, refinery, and power generation plants.
- Boilers and superheaters in thermal and nuclear power stations.
- Reheaters in steam turbine systems.
- Condensers for industrial heat recovery systems.
- Petrochemical heaters for process units and reactors.
- Their strength, toughness, and oxidation resistance make them suitable for both new projects and maintenance replacements in demanding service environments.
