Whole manufacturing process is thoroughly monitored and includes the following tests and inspections: receiving inspection of all raw materials and sub-supplies, in-process inspection during manufacture of individual parts, assembly tests, pressure tests, functional tests, non-destructive tests, final inspection of finished products. Pressure tests All pressure tests are performed in accordance with API 598, API 600, API 6D and DIN MSA also performs special tests according to API 6D a standard. Acceptance criteria is zero leakage. MSA also performs test by full operating pressure as a standard. This is the only test which can reveal possible leakage in the body-cover joint, stem, accessories, grease fittings etc. Ultrasonic test Cycle test X-Ray test Pressure test 28

29 Research and Development 9 MSA specialists deal with research and development activities and before creation of a new product they verify its properties, such as: fitness of materials used design strength and rigidity (FEM method) design functionality with stress on tightness and controllability hydraulic and aerodynamic properties etc. New product is tested both at MSA testing rooms, as well as in real service conditions. Product properties are regularly monitored during its whole service life and findings are applied for development and manufacture of new products. 29

30 10 Certificates Special tests MSA performs many special tests, by which we verify properties of our valves. All tests are witnessed by independent test institutes. The following tests were performed on MSA valves: Fire test according to API 6FD, API 607 and BS 6755, part 2, for Class 150, 300, 600, 900 and 1500 Tightness tests packing tightness test by methan Cycle test test for 3000 cycles (open-close) with water Hydrodynamics and aerodynamics test verification of hydropneumatic and aerodynamic properties Functional test All valves are functionally tested. Non-destructive tests MSA performs non-destructive tests in its own test rooms and equipment. Non-destructive tests include RT, MT, UT or DP tests. Personnel performing these test is highly qualified and certified according to EN 473 or SNT-TC-1A. Visual inspection Visual inspection is done on all castings used for MSA valves accordance with MSS SP-55 quality regulation for steel castings and corresponding specification in order. Certification MSA quality system is based on strict observance of EN ISO 9001:2000 and API Spec Q1 (Specification 6D number 0239). 30
