Description

 What is ASTM A269 Hydraulic Steel Tube?

ASTM A269 is a standard specification for seamless and welded austenitic stainless steel tubing for general corrosion-resisting and low- or high-temperature service. It is commonly used in various industries, including hydraulic systems, where durable and corrosion-resistant tubing is required.

1. ASTM A269 Hydraulic Steel Tube Material:

ASTM A269 specifies the use of austenitic stainless steel grades, such as 304, 304L, 316, and 316L, for the manufacturing of hydraulic steel tubes. These grades offer excellent corrosion resistance and mechanical properties.

2. ASTM A269 Hydraulic Steel Tube Size Range:

The standard covers tubing sizes from 0.125 inches (3.18 mm) to 1.5 inches (38.1 mm) in outside diameter and 0.01 inches (0.25 mm) minimum wall thickness.

3. ASTM A269 Hydraulic Steel Tube Fabrication:

ASTM A269 tubing can be produced as either seamless or welded. Seamless tubes are manufactured by piercing a solid billet and then extruding it over a mandrel to form the tube. Welded tubes are made from strip or plate by forming and welding the longitudinal seam.

4. ASTM A269 Hydraulic Steel Tube Surface Finish:

The standard specifies that the tubes should have a smooth, bright annealed or pickled surface finish or Polished. The surface roughness requirements ensure optimal performance in hydraulic systems.

5. ASTM A269 Hydraulic Steel Tube Mechanical Properties:

ASTM A269 tubing is designed to meet specific mechanical properties such as tensile strength, yield strength, and elongation. These properties ensure the tubes can withstand the pressures and forces encountered in hydraulic applications.

6. ASTM A269 Hydraulic Steel Tube Proformance

Corrosion Resistance: Austenitic stainless steel grades have excellent corrosion resistance, making ASTM A269 tubes suitable for hydraulic systems exposed to various corrosive environments, including chemicals and moisture.

Temperature Range: ASTM A269 tubing is designed to withstand a wide range of temperatures, from cryogenic conditions up to high-temperature service. The specific temperature range depends on the stainless steel grade used.

Compliance: ASTM A269 is a widely accepted standard in the industry, and tubes manufactured to this specification meet rigorous quality control standards. Compliance with ASTM A269 ensures the tubes consistency, quality, and suitability for hydraulic applications.

7. ASTM A269 hydraulic steel tubes main applications:

(1). Hydraulic Systems: ASTM A269 tubes are commonly used in hydraulic systems for the transmission of fluids or power. They are used in hydraulic cylinders, valves, pumps, and other components where reliable and high-performance tubing is required.
