The P265GH designation indicates that this steel is designed for use in pressure vessels and boilers operating at elevated temperatures. The EN-10217-5 specification sets out the technical requirements for welded steel tubes for pressure purposes, including requirements for chemical composition, mechanical properties, and dimensions.

Mechanical Properties

The mechanical properties of Welded Steel Pipe P265GH, EN-10217-5, depend on the heat treatment and the welding process used to manufacture the pipe. Generally, the mechanical properties of this steel include:

Steel name: P265GH

Steel number: 1.0425

Tensile strength: 410-570 Mpa

Yield strength: 265 MPa minimum

Elongation: 22% min

Impact strength: -20°C, ≥ 27J

These properties make Welded Steel Pipe P265GH, EN-10217-5, suitable for use in pressure vessels and boilers operating at elevated temperatures. The yield strength of 265 MPa means that this steel can withstand high levels of stress without deforming, while the high elongation ensures that the pipe can withstand deformation before failure. The impact strength indicates the toughness of the steel, making it resistant to brittle failure in low-temperature environments.

Inspection and testing

The inspection and testing of Welded Steel Pipe P265GH, EN-10217-5, are critical to ensure the pipe's quality, safety, and reliability for its intended use in pressure vessels and boilers. The inspection and testing can include the following:
1. Visual inspection: The pipe's external surface is visually inspected for any defects, such as cracks, deformations, or surface irregularities.
2. Dimensional inspection: The pipe's dimensions are checked to ensure they comply with the EN-10217-5 specification.
3. Non-destructive testing (NDT): This can include ultrasonic testing, radiographic testing, or magnetic particle testing to detect any internal defects or imperfections in the welds.
4. Mechanical testing: This includes tensile testing, impact testing, and hardness testing to verify the mechanical properties of the steel.
5. Chemical analysis: The chemical composition of the steel is analyzed to ensure it meets the requirements of the EN-10217-5 specification.
6. Pressure testing: The pipe may be subjected to hydrostatic pressure testing to verify its ability to withstand the design pressure without leaking or failing.
All inspection and testing activities are typically carried out by qualified personnel, following established procedures, and documented according to industry standards.

Pressure and Temperature Ratings of

The pressure and temperature ratings of Welded Steel Pipe P265GH, EN-10217-5, depend on several factors such as the pipe's size, wall thickness, and the operating conditions. The following information provides general guidelines for pressure and temperature ratings:
1. Pressure rating: The pressure rating of the pipe is determined by the design pressure of the system and the pipe's dimensions and material. The pressure rating can range from PN 6 to PN 100.
2. Temperature rating: The temperature rating of the pipe is determined by the maximum temperature that the pipe can safely withstand without degrading its mechanical properties. The temperature rating can range from -20°C to 400°C.
It's important to note that the pressure and temperature ratings of Welded Steel Pipe P265GH, EN-10217-5, are affected by several factors such as the operating conditions, the type of fluid or gas being transported, and the presence of corrosive substances. Therefore, it's essential to consult the relevant codes and standards to determine the exact pressure and temperature ratings required for a specific application.

Standard marking for welded steel tubes

Welded Steel Pipe P265GH, EN-10217-5, is typically marked with several pieces of information, including:
1. Manufacturer's name or trademark
2. Pipe dimensions (outer diameter, wall thickness, and length)
3. Steel grade (P265GH)
4. Manufacturing standard (EN-10217-5)
5. Batch or heat number
6. Pressure class or pressure rating
7. CE marking (indicating compliance with European Union regulations)
8. Additional markings may also be added, such as coating specifications, inspection and testing details, and customer-specific requirements.
The markings are typically applied to the pipe's surface using a durable method that ensures they remain visible throughout the pipe's service life. The markings help to identify the pipe's properties, manufacturing information, and compliance with relevant standards, making them an essential part of quality control and traceability.

Standard packing for steel Tubes

The standard packing of Welded Steel Pipe P265GH, EN-10217-5, is designed to protect the pipe during transportation and storage, ensuring it reaches its destination in good condition. The standard packing may include the following:
1. End caps: Plastic or metal end caps are used to protect the pipe's ends from damage during handling and transport.
2. Bundles: The pipes may be bundled together using steel straps or nylon straps to prevent them from moving around during transport.
3. Plastic wrapping: The pipes may be wrapped in plastic film to protect them from moisture and dust.
4. Wooden crates: The pipes may be packed in wooden crates for added protection during transport.
The packing method may vary depending on the pipe's size and quantity, as well as the customer's specific requirements. It's important to ensure that the packing is adequate to protect the pipes from any damage during transport and storage, and that the packing materials are environmentally friendly and safe for handling.
