liquid pipeline coating

Denso Protal 7200 can be applied by brush.

Denso North America offers a variety of pipeline coatings among its broad range of anti-corrosion and sealing products for infrastructure, oil and gas, and more. One of the most potent examples is Protal 7200 – a quick-curing, high-build liquid pipeline coating that has been formulated specially to complement FBE-coated pipe. Users can easily apply this two-part, 100 per cent solids epoxy coating in only one pass, either in the shop or in the field.

Resistance of high temperatures

One of the key advantages of using Protal 7200 is that it cures extremely quickly, which enables faster handling and backfill times. This liquid pipeline coating is recommended for many pipeline-related applications, such as onsite protection of girth welds, tie-ins, welds for boring applications, FBE repairs, push-rack applications, station piping, fittings, and fabrication. In addition to these, workers often choose Protal 7200 for mainline coating, sacrificial coating for direction drill and road bore pipe, and rehabilitation of existing pipelines.

Major features and benefits of this Denso coating include the following:

  • compliance with AWWA C-210-92 and CSA Z 245.30;
  • environmental responsibility;
  • fast touch-dry and set times;
  • high abrasion resistance;
  • high adhesion;
  • high build – of up to 70 mils or 1,778 microns in one coat;
  • outstanding self-levelling characteristics;
  • temperature resistance of up to 95 degrees Celsius; and
  • variety of packaging options.

Protal 7200 is applicable by either brush or spray. When applying it by brush, the user should initially prepare the surface with grit blasting, then stir the base and hardener until the mixture has a constant colour. Next, the mixed material should be applied to the surface and brush to the desired mil thickness. Preheat surfaces below ten degrees Celsius in order to get a faster cure.

To apply by spray, an XP70 Plural Component Sprayer is recommended. This device mixes and atomizes 100 per cent solids epoxies. A wet-on-wet spray technique is required to reach a thickness of at least 508 microns, measuring the coating thickness with a wet-film thickness gauge. Workers must be trained by Denso representatives beforehand to ensure correct use.
