Tub sense soldadura d'acer inoxidable ASTM SA213

ASTM A213 is a standard specification for seamless ferritic and austenitic alloy-steel boiler, superheater, and heat-exchanger tubes. This specification covers minimum wall thickness, seamless, and cold-drawn low-carbon steel tubes for tubular heat exchangers, condensers, and similar heat transfer apparatus.

The dimension of the ASTM A213 Stainless Steel Seamless Tube can vary depending on the application and are provided below:

1. Outer Diameter: 6.00 mm to 1020 mm
2. Gruix de paret: 0.50 mm to 75.00 mm
3. Length: Maximum 12.5 meters

This specification is generally used in high-temperature service applications, such as superheaters and reheaters in power plants, chemical and petrochemical industries, and refineries. The tube is also suitable for heating elements, condensers, cryogenic vessels, and similar applications. Additionally, ASTM A213 tubes are suitable for corrosive and high-temperature applications where high durability and wear resistance are required.

En resum, the ASTM A213 Tub sense costura d'acer inoxidable is designed for high-temperature applications in various industries and offers a durable and reliable solution for heating and cooling systems that require high strength, corrosion resistance, and thermal efficiency.

ASTM A213 is a specification for seamless ferritic and austenitic alloy-steel boiler, superheater, and heat-exchanger tubes. Stainless steel seamless tubes that conform to this specification are used for high-temperature service and are produced using various manufacturing processes. Here is a general overview of the manufacturing process of ASTM A213 stainless steel seamless tubes:

1. Raw material selection: The first step in the production process is to select the appropriate raw materials, which in this case is high-quality acer inoxidable.

2. Melting and casting: The raw materials are melted in a furnace and cast into billets or blooms.

3. Hot rolling: The cast billets or blooms are then hot rolled into seamless tubes using a mandrel mill or a plug mill.

4. Cold drawing: The hot-rolled tubes are then pulled through a series of dies to reduce their diameter and wall thickness. This process is known as cold drawing.

5. Heat treatment: The tubes are then heat treated to enhance their mechanical properties and remove any residual stresses.

6. Finishing: The tubes are then finished by cutting, cleaning, deburring, and testing to ensure they meet the required specifications.

7. Final inspection and packaging: The finished tubes undergo a final inspection and are then packaged and shipped to their destination.

Overall, the manufacturing process of ASTM A213 stainless steel seamless tubes involves a combination of melting, casting, hot rolling, cold drawing, heat treating, finishing, and inspection processes to produce tubes that meet the required specifications for high-temperature service.

ASTM A213 is a specification for seamless ferritic and austenitic alloy-steel boiler, superheater, and heat-exchanger tubes. The material grades covered in this specification include T2, T5, T9, T11, T12, T22, T91, and T92.

The seamless tubes manufactured according to this specification are intended for high-temperature and high-pressure service. The tubes must be heat-treated before use to improve their mechanical properties.

The tubes must also undergo various tests, including dimensional inspection, visual inspection, hydrostatic or nondestructive electric testing, eddy current testing, and flaring and flattening tests.

The sizes of the tubes available under this specification range from 1/8″ NB to 5″ NB (10.3mm to 127mm OD) and from 0.015″ to 0.500″ gruix. The lengths of the tubes are generally 6 meters or as per customer requirements.

The ASTM A213 Stainless Steel Seamless Tube specification covers different types of stainless steel grades, including austenitic and ferritic steels. Some of the commonly used grades include 304, 304L, 316, 316L, 321, and 347. These tubes are mainly used in various applications, including petrochemical, power generation, and offshore drilling operations.

ASTM SA213 Stainless Steel Seamless Tube is widely used in various industries such as:

1. Petrochemical industry
2. Oil and gas exploration
3. Chemical processing
4. Food processing
5. Pharmaceutical industry
6. Automotive industry
7. Power generation
8. Aerospace industry
9. Medical equipment
10. Marine industry

These seamless tubes are extensively used in high-temperature and high-pressure applications due to their excellent resistance to corrosion, oxidació, and extreme temperature conditions. They find application in piping systems for conveying hot and corrosive fluids, as heat exchanger tubes, and in boiler tubes for high-pressure steam applications. They are also widely used in industries that require hygienic and sterile conditions, such as the food and pharmaceutical industries. Furthermore, these tubes are essential in the construction of aircraft and components that encounter extreme environments, such as rocket exhausts and turbines.
