QUALITY SYSTEM INSPECTION & TESTING
QUALITY SYSTEM
在中国的国外阀门中少有的 SIL 3 功能安全性 认证。球阀要求SIL 3 认证最新的概念是由国
外煤气化工艺专利商引入中国的。
Dafram Quality Assurance System was certified for the first time in year 1988 by RINA. Today the whole Dafram ball valves design, manufacturing and testing process is covered by a quality assurance program certified and continuously audited by inspection authorities in accordance with:
INSPECTION & TESTING
According to written procedures the whole manufacturing process of ball valves is continuously monitored by the following inspections and tests performed during:
• ISO 9001-2000 for Design, production and after sales of ball valves • API Specification Q1 • Pressure equipment directive 97/23/EC (PED) • SIL 3 for functional safety • Directive 94/9/EC for equipments and protective systems intended for use in potential atmospheres (ATEX) • ISO 14001- 2004 for environmental management system of the company organization

long experience gathered during its more than 50 years of activity ensures that DAFRAM is one of the most famous and competitive companies all over the world. DAFRAM’s factory is located in Urbisaglia (Macerata), the centre of Italy on an industrial estate of 32.000 square meters, 12.000 which are covered surface. The factory consists of commercial, technical and engineering offices and of two extremely modern workshops the last of which, 4200 square meters, 10 meters high, completed in February 2008, allows the production, assembling, testing, sandblasting and painting of ball valves up to the largest sizes and weights. The Dafram design and production staff includes high qualified engineers with a long experience in meeting any standard and special customer’s requirements. Modern design methods are employed to analyse specific stresses and deformation limits of valve bodies and main valve components. The manufacturing process has been continually improved and renewed with the most advanced manufacturing technologies such as: multi-function machining centers and several computer controlled lathes. Special testing centers are used for testing of all production and specifically for TRUNNION MOUNTED valves in high pressure and big size executions. Both vertical and horizontal testing machines as well as equipments to detect the valves operating torque, to test valves in low and high temperature, allow DAFRAM’s prototypes to be checked and verified at site and production to be 100% tested, controlled and certified before leaving DAFRAM’s plant.
