Product description:

High-pressure boiler steel pipes are steel pipes 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 SA210 High-pressure boiler tube is a seamless carbon steel tube specifically designed for use in high-pressure and high-temperature boilers, heat exchangers, and superheater systems. Manufactured according to the ASME SA210 / ASTM A210 specification, these tubes provide exceptional mechanical strength, dimensional accuracy, and resistance to oxidation and corrosion in elevated temperature service environments.

Standard Overview

The ASME SA210 standard covers medium-carbon seamless steel tubes used in boilers, superheaters, and heat exchangers that operate under high pressure. It includes two major grades:

Grade A-1: General-purpose boiler tube with moderate strength and good formability.

Grade C: High-strength grade designed for elevated pressure and temperature service.

Both grades are engineered for performance in systems where heat transfer efficiency, pressure containment, and long service life are critical.

Manufacturing Process

The production of ASME SA210 high-pressure boiler tubes involves the use of high-quality carbon steel billets, which undergo a seamless forming process to ensure superior integrity and strength. The manufacturing steps include:

Hot rolling or extrusion: Billets are heated and formed into hollow tubes without welds.

Cold drawing (optional): Improves dimensional tolerance and surface finish.

Heat treatment (normalizing or annealing): Refines grain structure and enhances ductility.

Hydrostatic and non-destructive testing: Ensures tubes meet ASME quality and safety standards.

Surface finishing: Black, varnished, or oil-coated to prevent rust and oxidation.

This process guarantees a uniform, high-quality seamless boiler tube capable of performing under the most demanding conditions.

Key Features

High-temperature strength: Maintains excellent performance in temperatures exceeding 450°C.

Superior pressure resistance: Designed to withstand high internal pressures without deformation.

Excellent corrosion and oxidation resistance: Ideal for steam and heat transfer applications.

Uniform wall thickness and roundness: Ensures consistent performance and safety.

Smooth internal surface: Promotes efficient heat transfer and minimizes scaling.

Customizable specifications: Available in different grades, sizes, and surface conditions.

Applications:

The application scope of seamless steel pipes is very wide, including structures, fluid transportation, low to 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. The use of seamless steel pipes will ensure no leakage problems, guarantee the usage effect, and improve material utilization. It can be seen that the application of seamless steel pipes mainly covers three major fields. The first is the construction field, which can be used for underground pipeline transportation, including extracting groundwater during construction. The second is the processing field, which can be used for mechanical processing, bearing sleeves, etc. The third is the electrical field, including gas pipelines and fluid pipelines for hydropower generation.

ASME SA210 high-pressure boiler tubes are widely used in industries requiring reliable heat and pressure containment, including:

Power generation: Steam boilers, economizers, superheaters, and reheaters.

Petrochemical industry: Refinery heaters, thermal power units, and process piping.

Industrial boilers: High-efficiency heat transfer tubes for chemical and food processing plants.

Oil and gas: Steam injection systems and heat recovery units.

Marine and shipbuilding: Marine boilers and exhaust heat systems.

Their combination of strength, heat resistance, and dimensional precision makes them a trusted material in modern boiler manufacturing and maintenance.
