5. Quality Control / Assurance Get all materials together and perform MTR’s (Material Test Report) - Check the following: Material Thickness Material Grade, etc. If required, perform a PMI (Positive Material Identification) test Weld the bellows can and perform a dye-penetrant test on the long seam If required, x-ray test the bellows and/or pipe spool and pieces If the tests are good, next punch the bellows and perform a dye penetrant test Weld the punched bellows to the spool and/or flanges - (referred to as the attachment weld) and perform a dye penetrant test on the attachment welds If required, perform a pneumatic test, vacuum test, and/or a hydro-test Final Dimension Inspection - Check over the entire assembly: overall length diameters cosmetics accessories tags, etc. Bellows QC Process SASOL Quality Assurance Plan 100% x-ray 100% dye pen Hydro-test Pneumatic Test Positive Material Identification (PMI) Specific SASOL paint procedures

13. Manufacturing Capabilities Bellows Materials Based on operating temperature + media + pressure requirements + desired life cycle 300 Series Stainless Steel (any type of general service: H=high temperature, L=low carbon content) 304, 604L, 304H, 316, 316L, 316H and 321 High Nickel Materials Monel 400 (sea water, high corrosive) and Inconel 600 (seawater/marine) Inconel 625 LCF (low cycle fatigue): oil refineries & chemical plants in high temperature service due to high strength at high temperatures Hastelloy C-276 (highly corrosive service – destruction of toxic gasses, sulphuric acid plants) Incoloy 800 / 800H and 825 (high temperature applications)

14. Manufacturing Capabilities Materials: Single layer PTFE: temperatures up to 600°F 3-layer Belt and Insulation Pillow: temperatures up to 2,000°F Inside Layer: 100% fiberglass, coated with an aluminum compound on both sides Middle Layer: ½” thick KO wool Outside Layer: PTFE fiberglass reinforced Capacity: 40’ Length and 20’ Wide Fabric Expansion Joints Duct Expansion Joint – Low Temperature Duct Expansion Joint – High Temperature (up to 1200°F) 10’ square fabric expansion joint w/ high temp. and corrosion resistant composite belt

15. Manufacturing Capabilities GE Standard: Liner and flange used to be 2 pieces We combined the liner and flange into one piece As result, there is less welding for us and a smoother flow in the duct work for them Fabric Expansion Joints
