Imported raw material Particular cooling flow and self-recovery ; No V.O.C. material Easy operation without being heated The procedure is applicable to pipe, valves, flanges, tanks and abnormal shaped machine and parts, and take valve flange as example hereunder. 1. Pretreatment of surface Before surface of pretreatment, get rid of rust and paint, sundries and dust on the surface. And rust removal grade is up to St2 in GB/T8923 Rust Grade and Derust Grade on Steel Surface Before Painting Work . 2. Filling of PipeCoat Visco-Elastic Coating paste PipeCoat Visco-Elastic Coating paste is used to fill unevenness on valve, flange, joint and bolt and other irregularities for smoothnessto avoid creation of bridge and hollow at binding of tapes. 3. Binding of PipeCoat Visco-Elastic Coating tape Spiral binding is used to bind tape tightly on the paste with overlapping over 25mm and overlapping length of ends of tape shall not be less than 100mm and end shall be at 5 o’clock direction of piping, press the tape end to avoid warping. And remain certain of stress of the tape to keep it on workpiece surface during binding process and to flatten any wrinkles and gaps. Not to lay tape too long. 4. Binding of external protective band External protective band shall be bond on PipeCoat Visco-Elastic Coating tape by PP or PE and PVC protective band with proper width, and overlapping length of tape ends shall not be less than 100mm and shall be at 5 o’clock direction of piping, press tape end to avoid warping. And remain certain of stress of the tape to keep it on the workpiece surface during binding process and to flatten any wrinkles and gaps. Not to lay tape too long. PipeCoat Visco-Elastic Coating Product Feature ØImported raw material ØParticular cooling flow and self-recovery ; ØNo V.O.C. material ØEasy operation without being heated ØNo hardening, crack and peeling-off; ØGood bonding nature to insolate water and air ØGood sealing with long term corrosion protection. ØStable chemical performance and good capacity against cathode peeling.ØLess demand for surface treatment, St2 grade Ø Capable to bind 3PE,FBE and epoxy PipeCoat Visco-Elastic Coating tape Product, with imported visco-elastic polymer as main composition, is added with preservation anti-oxygen and anti-UV agent, as well as a layer of tensile-proof fiber mesh at its interlayer. Such flexible visco-lastic tape is manufactured with mixing and painting procedures with characteristic of toughness, bonding and resilience honored with title of Band aid of pipeline, and such products are widely used in corrosion proofing field and water sealing field such as petroleum, petro chemistry, gas, chemical processing, water conveying, thermal preservation, power, cable, construction and highway. Flexibility plasticity of PipeCoat is easy to be used uneven of parts and is available to form various shape with self-flow and coat overage rate is up to 100%.The excellent cohesive forceof PipeCoat is essence for its sealing capacity and its plasticity is key to be used for any shape changes of prime substrate and deform. And PipeCoat is characterized with self-recovery after being damaged. PipeCoat with corrosion prevention principle of Bonding and Sealing is to satisfy application demand such as piping work and pipe fitting.
