ASTM A106B/ASME SA106B American Standard Seamless Steel Pipe 355.6 * 7.92 for High Temperature and High Pressure Service

ASTM A106B/ASME SA106B is a standard developed by the American Society for Testing and Materials (ASTM) and the American Society of Mechanical Engineers (ASME) to specify the technical requirements for seamless carbon steel pipes, particularly suitable for high-temperature and high-pressure services. These steel pipes are commonly used in pipeline systems in industries such as oil, natural gas, chemical, and power.

For the ASTM A106B/ASME SA106B seamless steel pipe 355.6 * 7.92 for high temperature and high pressure, where 355.6 is the outer diameter of the steel pipe (usually in millimeters) and 7.92 is the wall thickness of the steel pipe (usually in millimeters).

Here are some basic information about this type of steel pipe:

Material: ASTM A106B/ASME SA106B steel pipes are made of carbon steel and have good mechanical properties and weldability.

Application: These steel pipes are commonly used in pipeline systems that need to withstand high temperatures and pressures, such as oil and gas pipelines, refineries, chemical plants, power plants, etc.

Dimensions: Outer diameter 355.6 mm, wall thickness 7.92 mm. These dimensions are selected based on specific engineering requirements.

Standards: ASTM A106B and ASME SA106B are two equivalent standards developed by ASTM and ASME respectively. These two standards specify the requirements for the chemical composition, mechanical properties, dimensional tolerances, surface quality, and other aspects of steel pipes.

Quality control: Manufacturers of these steel pipes need to follow strict quality control procedures to ensure that the pipes meet the requirements of the standards. This includes chemical composition analysis, mechanical performance testing, dimensional inspection, surface quality inspection, etc.

Weldability: ASTM A106B/ASME SA106B steel pipes have good weldability and can be connected through various welding methods. However, appropriate pre-treatment and preparation work is required before welding to ensure the quality and performance of the welded joint.

It should be noted that the specific performance and application of steel pipes also depend on factors such as their chemical composition, heat treatment state, manufacturing process, etc. Therefore, when selecting and using these steel pipes, it is necessary to refer to relevant standards and specifications, and consult professional engineers and technicians.
