ASME A213 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 A213 Heat exchanger seamless pipes are high-quality alloy and stainless steel tubes designed specifically for boilers, superheaters, condensers, and heat exchangers operating under high-temperature and high-pressure conditions. Manufactured in accordance with the ASME SA213 / ASTM A213 specification, these tubes provide exceptional thermal conductivity, corrosion resistance, and mechanical strength, ensuring reliable performance and long service life in power generation, petrochemical, and energy industries.

Product Overview

ASME A213 Seamless Heat Exchanger Tubes are manufactured from ferritic and austenitic alloy steels using precision cold-drawn or hot-finished processes to ensure dimensional accuracy and smooth inner surfaces. These pipes are widely used in boilers, condensers, and heat exchangers, where they efficiently transfer heat between fluids under demanding thermal cycling conditions.

Their combination of high tensile strength, oxidation resistance, and excellent thermal stability makes them ideal for steam generation, chemical processing, and refinery heating systems.

Manufacturing Process

• Raw Material Selection: Premium alloy or stainless steel billets are chosen to meet ASME A213 chemistry requirements.
• Piercing & Hot Rolling: Billets are heated and pierced to form seamless hollows, followed by hot or cold rolling for accurate wall thickness.
• Cold Drawing: Achieves high dimensional precision and excellent surface finish.
• Heat Treatment: Annealing, normalizing, or quenching and tempering to refine microstructure and improve mechanical properties.
• Inspection: Each tube undergoes eddy current, ultrasonic, hydrostatic, and dimensional testing to ensure zero defects.
• Surface Finish: Tubes are pickled, polished, or bright annealed to meet the requirements of heat exchanger applications.
• All products are delivered according to ASME SA213, ASTM A213, and EN 10216-2 standards with full Mill Test Certificates (MTC) under EN 10204 3.1 or 3.2.

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 A213 Heat exchanger seamless pipes are widely applied in high-performance industrial systems where heat transfer and reliability are critical:

• Power plants: Boiler and superheater tubes for steam generation.
• Refineries: Heater and reboiler tubes for crude distillation and hydrotreating.
• Petrochemical plants: Condensers, process heat exchangers, and reformer tubes.
• Desalination systems: Heat exchanger tubing for seawater applications.
• Food and pharmaceutical industries: Clean heat transfer systems using stainless grades.
• Their durability, corrosion resistance, and efficiency make ASME A213 tubes a preferred solution for both new installations and maintenance replacements.
