A question that comes up occasionally is, "Can I paint over the seal coat on Ductile iron pipe? Perhaps the more pertinent question is, "Should I paint over the outside shop coat? But before we answer either of those questions, we should ask for what purpose the user wants to paint over the seal coat in the first place. Is it for cosmetic purposes? Would it be intended as an identifying mark on the pipe? Or do they have some other purpose for changing or adding to the otherwise standard black asphaltic coating that the manufacturer typically provides?

Can a Sure Stop 350® Restrained Joint Gasket Be Used for Horizontal Directional Drilling?

By John Simpson P.E., ENV SP, NACE CT 10/01/2020 In Installation Products Technical

Those involved in the construction of water and wastewater pipelines are probably aware of the installation methodology of Horizontal Directional Drilling (HDD). HDD is a trenchless technique that provides an installation alternative offering several benefits over traditional open-cut. HDD can be implemented with minimal disruption to surface activities, requires less working space, and can be performed more quickly than open-cut methods. HDD can be used to install new pipelines or replace existing ones. Also, it can simplify or eliminate certain permitting processes. Although there are currently no national standards regarding HDD installations of municipal underground infrastructure systems, HDD has seen a dramatic increase in recent years and is becoming more common for any pipe material. HDD may be the fastest-growing trenchless construction method today.
