WHAT IS EPOXY COATED FLANGE?
The chief application of epoxy is as a coating on various metal products including pipes, flanges or even fasteners. The polymerization of epoxides forms an epoxy resin, which in turn is applied on the Epoxy Coated Flanges. The polymer is crosslinked, when this epoxy resin is thermostatically heated. The coating itself consists of two components. Firstly it is a resin and the next component is a hardener, which improves the durability of the Epoxy Coated Blind Flange.
TYPES OF EPOXY COATING USED FOR FLANGES?
The most common type of coating used on flanges is FBE, because of the several benefits they offer. For instance, the ASTM A105 FBE Coated Flanges have improved corrosion resistance and are much more durable than bare flanges, especially in industrial sectors like the oil and gas industry, or in the conveyance of potable water.
HOW LONG DOES EPOXY COATING LAST?
Since the Carbon Steel Flange PE Coating applied is a thermoset one, it is considered to be a permanent one.

CARBON STEEL FLANGE FUSION BONDED EPOXY COATING PROCESS
The process of coating application can be simply broken down into three steps. The first step would include cleaning the flange following which it is to be heated at the desired temperature. Once the flange is heated, a coating is applied to it. The last step involves curing the ASTM A350 LF2 Epoxy Coated Slip On Flange to permanently set it.
ADVANTAGES AND DISADVANTAGES OF FBE COATED FLANGES
Besides having a lower rate of corrosion, these ASME B16.5 Epoxy Lined Flanges perform much better as they are less likely to fail by stress-related cracking. Although there are some concerns with regards to the carcinogenic factors linking these coatings, they are known to not only be eco-friendly but also non-toxic.
