ASTM B704 welded UNS N06625, UNS N06219 and UNS N08825 alloy pipe

ASTM B704 is a standard specification for welding alloy pipes UNS N06625, UNS N06219, and UNS N08825. The following is a detailed analysis of the standard and the alloy pipes involved:

1. Overview of the standard

Standard Number: ASTM B704-2003 (or B704-03 for short)

Scope of application: This standard applies to welded UNS N06625, UNS N06219 and UNS N08825 alloy tubes, which are commonly used in equipment such as boilers, heat exchangers and condensers for general corrosion resistance and low or high temperature service.

Second, the main requirements

The ASTM B704 standard mainly specifies the following:

Tube Size:

Tubes range from 1/8″ to 5″ (3.18 mm to 127 mm) in outer diameter and wall thicknesses range from 0.015″ to 0.500″ (0.38 mm to 12.70 mm). Other sizes of tubing are also available, subject to other requirements of the standard.

Chemical composition and mechanical properties:

The standard details the chemical composition requirements for each alloy and specifies test methods and acceptance criteria for mechanical properties such as tensile strength, yield strength, elongation, etc.

Manufacturing & Inspection:

The manufacturing process of the tube is regulated, including the welding process, heat treatment, etc. At the same time, the standard also specifies the requirements for inspection and testing to ensure that the quality and performance of the tube meets the standard.

Ordering Information:

When ordering alloy pipes under this standard, you need to provide specific ordering information, such as quantity, size, length, grade, etc.

Third, the field of application

Due to their excellent corrosion resistance and high-temperature strength, these alloy tubing are widely used in a variety of industrial fields, including but not limited to:

Aerospace: used in the manufacture of engine parts, structural parts, etc.

Petrochemical: In the process of oil and gas extraction, processing and transportation, it is used to manufacture high-pressure and corrosion-resistant pipelines and equipment.

Energy: In the energy fields such as nuclear energy and thermal power generation, it is used to manufacture pipelines and equipment in high-temperature and high-pressure environments.

Chemical: used to manufacture chemical equipment and pipelines with strong corrosion resistance.

4. Precautions

When selecting and using alloy tubing under the ASTM B704 standard, parameters such as chemical composition, mechanical properties, dimensions, and tolerances of the product should be carefully checked to ensure that they meet actual needs.

The selection and use of products should comply with relevant standards and norms to ensure the quality and safety of products.

During use, attention should be paid to the maintenance and care of the product to prolong the service life of the product.Huanickel?related?products?strictly?implement?this?standard.?For?more?information?about?the?standard?and?the?corresponding?product?information,[email protected]
