DALAM 10217 is a European Standard that provides specifications for “Welded steel tubes for pressure purposes.” This standard includes multiple parts, each dealing with specific types of steel:

• DALAM 10217-1: Non-alloy steel tubes with specified room temperature properties
• DALAM 10217-2: Electric welded non-alloy and alloy steel tubes with specified elevated temperature properties
• DALAM 10217-3: Alloy fine grain steel tubes
• DALAM 10217-4: Electric welded non-alloy steel tubes for pressure purposes with specified low temperature properties
• DALAM 10217-5: Submerged arc welded non-alloy and alloy steel tubes with specified elevated temperature properties
• DALAM 10217-6: Submerged arc welded non-alloy steel tubes with specified low temperature properties
• DALAM 10217-7: Stainless steel tubes

Each part outlines the technical delivery conditions for a particular category of steel. While I can’t provide the full standards due to copyright restrictions, I can tell you that they generally cover the following topics:

1. Skop: Defines what the standard applies to.
2. Normative References: Lists other standards referred to in this document.
3. Terms and Definitions: Explains the terminology used in the standard.
4. Ordering Information: Specifies the details that should be provided at the time of inquiry and order.
5. Manufacturing: Describes the manufacturing and delivery process.
6. Requirements: Outlines the specific requirements for the steel, including mechanical properties, komposisi kimia, and testing methods.
7. Test Methods: Describes how to test the steel to ensure it meets the required standards.
8. Inspection and Certification: Details the inspection and certification process.
9. Menanda: Specifies what information should be marked on the steel.

To access the full standards with specific details, you would need to purchase them from an official standards organization or authorized reseller. Please respect copyright laws when accessing and using standards.

 

APPEARANCE OF EN 10217-1 PIPES

– Jahitan Kimpalan

The weld area of EN 10217-1 pipe is a critical component that must be free from cracks, lack of fusion, and lack of penetration. Any repairs to the weld seam of EW and HFW tubes are not permitted. Repairs to the weld seam of SAW tubes shall be allowed if done by an agreed documented procedure. This is to ensure the structural integrity of the pipe and to prevent any potential leaks.

– Tube Surface

EN 10217-1 pipe has specific requirements for its surface to be considered usable. The tube must be free of any external or internal surface defects that can be detected by a visual examination of the surfaces. Selain itu, the finish and surface condition should not be such that any surface imperfections would require dressing. Namun begitu, if it is necessary to dress the surface imperfections, they can only be ground or machined down. The wall thickness in the dressed area must not fall below the specified minimum wall thickness after dressing. Akhirnya, all dressed areas must blend smoothly into the contour of the tube without any visible imperfections.

b Elements not included in this Table shall not be intentionally added to the steel without the agreement of the purchaser, except for elements which may be added for finishing the cast. All appropriate measures shall be taken to prevent the addition of undesirable elements from scrap or other materials used in the steel making process.
b The content of these elements need not be reported unless intentionally added to the cast.
c Option 3: In order to facilitate subsequent forming operation, an agreed maximum copper content lower than indicated and an agreed specified maximum tin content shall apply.
d This requirement is not applicable provided the steel contains a sufficient amount of other nitrogen binding elements, which shall be reported.
