日本电装北America has coatings for high temperature pipelines
Protal 7900HTis a high temperature pipeline coating from Denso North America that offers many advantages.
It is a VOC-free, 100 per cent solids epoxy coating that protects pipelines from corrosion. This high build liquid coating can be either hand or spray applied in a single coat. The simple application means this coating is easy to apply, whether in a shop or in the field. Protal 7900HT also cures fast, which allows quick backfill when applying to a hot pipe.

This coating is typically used on pipe, valves, fittings, girth welds and fabrications in applications that involve elevated temperatures. The coating offers a number of features such as:
Simple application
Application of the Protal 7900HT pipeline coating is fast and easy. To give a better idea of just how easy the process is, here is a brief outline of the steps involved.
Whether applying by hand or spray, the surface should be cleaned by grit blasting. When applying by spray, a plural component airless unit should be used with a pump capable of a volume mixing ratio of 3:1. A wet on wet spray technique should be used until a minimum thickness of 20 mils is reached. If applying by hand, the minimum thickness should be no less than 30 mils. To measure the coating thickness, use a wet film thickness gauge.
