In standard EN 10253 (fittings) there is possibility to complete preparation of ends for welding also by beveling of outside edge on 30° and inside edge on 18° to axle of fitting (upon agreement only). 2. • Values are valid for products, where beveling is according standard ANSI B 16-25. • The values for beveling of ends according standard API 5L and for pipes according to ASTM A (ASME SA) are identic with standard EN. In case of preparation of inside edge angle can not exceed 7° to longitudinaly axle (T ≤ 10,5 mm) and 9,5° to T 10,5 –14 mm. (upon agreement only). • Pipe according to API 5 CT are delivered with square cut plain ends. Sulfide Stress Cracking (SSC) Resistant Metallic Materials - Requirements Material requirements for sulfide stress cracking are specified in american standards„NACE STANDARD MR“ The NACE MR0175 standard, also known as ISO 15156 (International Standard) was developed for the prevention of sulfide stress cracking due to H 2 S in oil and gas production system. The NACE MR0103 standard was developed to be a refinery-specific sour service materials standard. The standard provides recommenda- tions on which alloys and materials to use to prevent sulphide stress cracking in an H 2 S containing environment. Note: acronym “NACE” Has more meanings than one. “NACE” code means “Classification of Economic activities” which in Slovakia was known until now as “OKEC”. In our case “NACE International” is the leading international organization focusing on corrosion of materials. Current name is derived from the acronym of this organization “National Association of Corrosion Engineers”, which was founded in USA to address corrosion protection of tubings and pipes. Specifications of this American organization NACE International THE CORROSION SOCIETY labeled as NACE Standard MR (Standard Material Requirements) are establishing materials suitable to use in environment where there is Hydrogen Sulphide present.
