Cleaning & Repair July/August 2016 BULKDISTRIBUTOR 9 Flush with success Chemically bonded phosphate ceramics can stop corrosion on cleaning depot flush tanks T housands of chemicals, petroleum products, and corrosive elements like saltwater brine are transported by tanker truck, railcar and distributors, as well as processed in chemical tanks at facilities and refineries every day. At these sites, carbon steel corrosion can require early tank replacement and maintenance, as well as pose a safety risk in terms of potential leaks, spills, and even fire and explosion, so effective corrosion protection is a must. DFW tank before DFW tank after “We clean just about any tank hauling product or waste on the road or rail,” says Joe Svehlak, facility manager at DFW Tank Cleaning, based in Dallas-Fort Worth, Texas, USA. DFW is a full service tank cleaning facility that specialises in chemical cleaning. “Protecting against corrosion is vital in our facility flush tanks,” he adds. According to Svehlak, effective corrosion resistance in the flush tanks is necessary because they hold the wastewater from the first flushes of those tanks that the company cleans, which can include residual chemicals, until the water can be treated. This amounts to thousands of different residual chemicals held in the flush tanks annually – from petroleum products and saltwater brine to fluoride, caustic soda, and a variety of acids. Against such corrosion challenges, traditional polymer paints and rubber-type coatings have long been used as physical barriers to keep corrosion promoters such as water and oxygen away from steel substrates. This works until the paint is scratched, chipped, or breached and corrosion promote '2VFW"FRv&WGvVVFR7V'7G&FPB6FrआvWfW"G'V6"&FW'2VƖrv7FR6VFr6BB6VFVB6&R'F7V&ǐ&RF67&F6W262"'&V6W2FVFP6Fr67BƖRw&VVW6R( 2G&pvFW"vVBFW"6'&6&FW'2( 0v6w2FR6'&6F7&VBvP7FW727FVV6&RW6VBf"F2F&W67@6'&6B6&RWF6FW2&R67FǐF6&&7FVV2vV26VvrFvVBf'&6FRBFrWrvVW&FbF6'&66Fw26VB6V֖6ǒ&FVB7FP6W&֖724%7226VBF7F7V66'&6&fR6fWGBWFVBFƖfRFPG&7'BGW7G'B&WBvR֖֗6pFV6RBFvFRࠥ'VvvVB&FV7F( W"6'&6&FV7Ff"W"vfW6F22F&R'F7V&ǒ'VvvVB&V6W6PvR֗FRv7FWvFW"6BFW2B7G&Fg@6B&62BWfVWF6fw26&P&W6VBg&FRv7FRG&W'2vR6W'f6R( 607fV( FR6'&6&FV7F62FvF7FBFRvFVW&GW&Rv&W77W&PvFW"vRgFVv&vF( ХF6G&6'&6FRF6Vrf6ƗG66RFfRV2FW2&6VBD2WF67G'V7F&fFVǒvVB6琧7V6Ɨ6r7FVV67G'V7FBGW7G&B'VFr&V7G26BFR6FRbGvfW6F2FRfW6F2vW&R6FVBvF7&ƖVB&v26Fr6VBV6@g&FR&Vv'F6&Ɩ&6VB6琦bFR6RRV6B&W&W6VG2Wp6FVv'bFVv4%72FB67F6'&6ख6G&7BFG&FFǖW"6Fw2F@6BFbFR7V'7G&FRFR6'&6&W67F@6Fr&G2F&Vv6V֖6&V7FvFFR7V'7G&FRB6ƖvB7W&f6RFF7GVǐ&fW2FR&V7FW"2f&VBF2W2B76&Rf"6'&6&FW'0ƖRvVBV֖FGFvWB&VBFP6FrFRvFW6vF&F'G2FP6'&6&'&W"26fW&VB'6W&֖26VF@&W67G26'&6f&RvFW"'&66V֖62BFVW&GW&W2WFC +bFVvG&FFǖW"6Fw0V66ǒ&BF7V'7G&FW2FBfR&VVWFV6fVǒ&W&VBbvVvVB7GW&R@vVv֖w&FRVFW"FR6F~( 2fg&Ц6FW2bFRvVvR'6G&7BFR6RFvR6W6VBFFP6W&֖26FVB7V'7G&FRvB7&VB6'&6&V6W6RFR6&&7FVV( 27W&f6R2GW&VBFb7F&RFW26RFR7FVV( 27W&f6R07F&RFRv&RWF2ƖRvBB6fW &R7F&RBvvW"&V7BvFFPVf&VBB6'&FRf6&R66rVV7G&֖7&66PFw&V6BFW2BVfRv&WGvVVFR7FVVBFR6Fr&V6W6RFP&B26V֖6&FW"FV6666PFW&R2vWfVb7GW&Rv2FvW@F&VvFFR7FVVGVRFvVvRFW&R0vW&Rf"FR7GW&RFG&fVgW'FW"FRǒ7BFB66'&FR2FR67&&RƖPG6Vbv6VƖ֖FW2FR76&ƗGbFP6'&6֖w&Fr( VƖRG&FFWFG2FR6'&6&W67FB6Fw2f"֖B7FVVfRFV&PW"b&FV7F( 62&&'&'2D0WF67G'V7F"f&V( FRFVvWG6FR6W&֖26FrvB6ƖRB@FW26F&7FrF&VfRFR6V֖6ǐ&FVBW"7F26'&6BvBp6'&6&FW'2F7&VB( Ю( V6B27FBW&VǒvVFWfW'Frg&6V֖62B6G'&RF'&6v&W77W&RvFW"BVB( FG07fV( Ē&VƖWfRBvFV&RFRƖfRbW F2vR6vf6FǒvW&rFV6P67G2BFvFR( Ф66&FrF7fVFR6F~( 2F6'&6&W'FW26VB6&VVfBvFP&vRbG&7'B&VFVB'W6W76W2( FW"G'V6B&W&F26&VVf@g&FRF6'&66F~( 2&VƖ&ƗG( 607fV( ėG2'&6&W67F6R2&rW2f v7FWvFW"VƖW'2"7WW"7V6W"G'V6W&F'2vFf7WVF2FBV6VFW WF62v726&G2WF2vV6VrW@6FrƖ6FFRF氠7V2Bv6&W67BF6'&6vVG&7'FrWG&WV&GV7G2"WfVW6V@&W7FW&Bv7FR7V62fB"w&V6R( Фf"G&7'B6W2rF&VGV6R67G2FW&R&RFFFGfFvW2F4%26Fw0&WB6'&6&W67F6RF26VFW2V6&WGW&F6W'f6RFB֖֗6W2WVV@FvFR2vV2d72"2BfR7&VB&FrbW&v6&fW26fWGf"6'&6&FV7F&V7G2W6rG6ǖW"G27V62ǗW&WFW2"WW2FR7W&RFR&RF2"vVV2&Vf&RFPWB6BbG&FF( F&VR'B77FV>( 6&RƖVBFWVFrFR&GV7BFR7W&PFR2V6W76'FrV66BF6WfPG2gV&W'FW2WfVFVvBfVVG'FFRFV6ख6G&7B6'&6&W67FB6Frf 6&&7FVVW6rFR6W&֖26Fr6vP6B&WV&W27B7W&rFR&WGW&F6W'f6R6&R6WfVB2ƗGFR2RW"F2Bb7VVBvWGFrFFW"G'V6"&6"W&Frv66fR6vf6Fǒ&VGV6VBFvFR( gFW"&&FRF&W&FvRfV@FBbvR7&V6BFR&rFRF氦6&R&WGW&VBF6W'f6RFR6RF&V6W6R@ƖW2R6BBG&W2V6ǒ( 62&'2V6B667G2bGvֆ&FW06VG2FBFBFW&7BVFƖV@'W&7&77FVƖRF6R6ǐW6VBFǒǗW&WFRf"ǗW&6Fw266RFR6Fr2&v2FW&P&Rd722BFW"F2V0FBFR6Fr6&RƖVB6fVǒWfV6fVB76W2( 66RFR6'&6&W67FB6Fr0d722"FW"vRvW&R&RF7&GW&rv&W'26v&WBFFPF26VB6FVRvRvR6FVBFV( Ц66VFW2&'2( f"Ff6ƗG G&7'B&VFVBW&FvF6'&677VW2B2vVv'F66FW&r( ЧwwrV6B6Р
