Position of any point of main steel Position of support node 2 6. Structural Steel Design, 5th Ed. Selection of a better steel quality level in norsok m 101 than the minimum required by noreok designer shall not lead to more stringent requirements in fabrication.

Norsok m ed 5 , Oct _百度文库

norsok m 101 Any occurrence of cracking during production welding shall be investigated. Annexes B, C, D and E are normative. The external norsok m 101 shall not depart from the nominal external circumference by more than the following Ref. Edition 5 of this NORSOK standard has been necessary due to an extensive change in referenced international standards.

All traces from previous grinding shall be completely removed. A low defect rate may be used as basis for a reduction in the extent of NDT for inspection categories B, C and D, provided that a correct defect rate identification is prepared for each weld method, each NDT method and each production area.

The moment new editions of the standards norsok m 101 monitor are released, changes are made, or appendixes are published, you will be alerted by email. Three 3 valid test specimens shall be obtained for each notch location. Guide on methods for assessing the acceptability of flaws in fusion welded structures.

See Note 2 in Table 9. The following documents shall be prepared prior to start of fabrication: Each individual product brand name and dimensions shall norsok m 101 tested once per batch, except for norsok m 101 wire originating from the same heat, where one diameter may represent all.


Global grid system Local grid system Max. Survey Reference System A reference system constituting of fixed and coordinate determined points, from where surveys can be performed, and where the location and elevation of the fixed points are identifiable relative to the grid system. Economics of Structural Norslk Work. Norsok m 101 consumables – Test methods – Part 1: Frequently asked questions by SAW fluxes do not require individual testing, while SAW wires shall be tested in combination norsok m 101 a selected, nominal batch of flux.

The purchaser shall base his selection, ordering and receiving of consumables upon reviewed and accepted data sheets. J level shall be in accordance with EN part 3, Class A. If sufficient documentation from the steel manufacturer is not available, a change of material shall require re-qualification of a reduced number of procedures.

The manufacturer shall have a quality system, which fulfil the relevant part of EN and the applicable level of EN Minimum norsok m 101 of weld profiles after blending should not be less than 10 mm. Local tolerances for sliding and pivoting ends shall be specified on the structural drawings.

Prior to fabrication start-up, contractor shall implement a system for recording norsok m 101 weld defect rates. The reference block shall be from a steel type that is representative for the steel to be inspected. However, ambiguous imperfections revealed by UT shall in addition be tested by RT.

For special structures such as jackets being built laying down,reference system must be adjusted to this fabrication situation, but the final as built survey shall be related to the platform grid norsok m 101. This ensures that you are always up-to-date and saves you both time and money.

The excavated groove shall be minimum 50 mm long, measured at defect depth even if the defect itself is smaller. Should is a recommendation. By controlled and certified chemistry the supplier norwok confirms that mechanical properties of the weld metal fulfil the minimum requirements specified for the product. Reference lines are marked lines on construction parts and assemblies. Magnetic yokes using alternating current shall be used. Length Position norsok m 101 of main box norsok m 101 Out of straightness 5.

Weld imperfections may be left without remedial work. Welding personnel – Approval testing for fully mechanised and automatic welding. For restrained norsok m 101 of complicated design, PWHT may be required for norwok thicknesses, independent of steel quality level. Subscription – always available and updated A web subscription provides an easy and secure access to standards, nirsok you are guaranteed to always have norsok m 101 latest edition. Testing shall be performed in accordance with EN and the additional requirements given below.

All tolerance requirements are based on nominal values on unloaded structure. Steel Fabrication Method Statement Atak cons. Monitoring Standards monitoring is a free service designed for you who wish to be alerted of changes to or new editions of the standards required in your work.

NORSOK Structural Steel Fabrication M-101

The depth of the groove is approximately 0. Local alignment of sleeves 20 mm. Chemical Analysis For solid wires and metal powders the analysis shall represent the product itself. Temporary attachments shall be cut minimum 3 mm from the base metal and ground. Circularity is defined as the difference between the actual and the average radius, both beeing norsok m 101 from the optimum norsok m 101 of the tubular. If elongated defects are situated on line and the distance between them is less than the length of the longest indication, the defects shall be evaluated as one continuous defect.

Where relevant, the contents of a NORSOK standard will be norsok m 101 to provide input to the international standardisation process. Single layer fillet welds qualifies multi-layer, but not the converse. Correct tool is essential to maintain correct peening in compliance with requirements. Final documentation shall be prepared in correspondence with the requirements for as built documentation and fabrication record.
