2205 Duplex Steel Pipe Sheet Introduction

2205 duplex stainless steel tube sheet is a high-performance material often used in the manufacture of equipment such as heat exchangers, condensers, and evaporators, especially in harsh environments such as the chemical, oil, and gas, as well as in the field of offshore engineering. 2205 duplex stainless steel excels at withstanding pressure and resisting corrosion due to its excellent mechanical properties and corrosion resistance, which makes the tube sheet excellent in withstanding pressure and resisting corrosion.

2205 Duplex Stainless Steel Tubular Sheet is an ideal material choice for the manufacture of critical equipment that requires resistance to high pressure and highly corrosive environments. Its excellent mechanical properties and corrosion resistance make it a reliable choice for many industrial applications.

Special Manufacturing Technologies

The fabrication of 2205 duplex stainless steel tube and plate usually involves the following technical steps:

Plate Cutting: Use of high-precision cutting techniques, such as water jet cutting or plasma cutting, ensures flat cuts and reduces heat-affected zones.
drilled hole: Advanced drilling techniques are used to create the tube holes, which are used to install the tubes. Drilling accuracy is critical to the overall performance and sealing of the tube sheet.
ream (i.e. widen a hole): Ensure proper fit clearance between the tube hole and the tube through the reaming process for welding or reaming fixing.

Advantages of 2205 stainless steel tube sheet

Excellent corrosion resistance

Due to its high chromium and molybdenum content, 2205 duplex steel tube sheet has much higher corrosion resistance than standard austenitic stainless steels such as 304 and 316. It performs particularly well in chloride-containing and seawater environments.

high strength

The yield strength of 2205 duplex steel pipe sheet is about 250MPa, which is twice as high as that of ordinary austenitic stainless steel, so the wall thickness can be reduced and the weight can be lightened when designing, thus reducing the cost.

Good welding properties

2205 Duplex Steel Pipe Plate has good welding performance and does not require preheating or post heat treatment. However, in order to maintain its excellent corrosion resistance and mechanical properties, appropriate heat treatment should be carried out after welding.

Good impact resistance

The duplex structure provides higher strength and toughness. The ferrite phase provides good impact resistance, while the austenite phase provides higher ductility and toughness.2205 Duplex Steel Pipe Sheet maintains good impact resistance at low temperatures.

Standards and Norms

The manufacture and use of 2205 Duplex Stainless Steel Tube and Sheet requires adherence to a variety of international and regional standards to ensure safety and efficiency. Some of the key standards include:

ASME (American Society of Mechanical Engineers): The ASME Boiler and Pressure Vessel Code, in particular, has stringent requirements for the design, manufacture and testing of tube sheets.
ASTM (American Society for Testing and Materials): Provides standards for material characterization and test methods.
EN (European Standard): For example, EN 13445, which covers the requirements for the manufacture of unpressurized packagings.

Application Areas

Duplex Stainless Steel is widely used in several applications due to its excellent mechanical properties and corrosion resistance. The following are some of the major applications of Duplex Stainless Steel:
