Coatings and Linings

Conference Paper - This paper describes the requirements of the standard, additional inspection points, and several uses of the standard in the field where clear specification language was imperative to successful project completion. NACE 5/SSPC-SP 12 standard confined to water jetting - which makes use of ultra-high pressure water that is nonabrasive.  Four levels of visible post-cleaning condition and three levels of non-visible condition are defined.

Two large scale problems with three layer polyolefin (3LPO) coatings are discussed here and possible reasons for the failures. Lessons learned and recommendations for future usage of such coatings are provided. 

Electrochemical and slow strain rate tests were done to demonstrate the protective ability of a thermal sprayed aluminum coating to prevent chloride stress corrosion cracking of TP304L SS in aqueous chloride solutions. Mitigation methods.

Use of nanotechnological methods for all types of coatings has become increasingly important. This paper aims to give an exemplified overview on the different ways of using nanoparticles in protective coatings with a special focus on materials for light weight constructions.

An effective barrier coating aims to minimize exposed surface area. A sacrificial layer requires a large exposed surface.to maintain long term protection of the substrate.  This work is to investigate this synergy in order to elucidate the factors that have the greatest influence over the corrosion protection properties and failure modes of TSN.

We will review the class of epoxies that can be classified as Ultra-high temperature epoxies that can be put in service at above 150 C. The topics in this paper will include the technological issues associated with ultra-high temperature epoxy systems.

An effort was executed, to leverage the inherent benefits of polysiloxane coatings, to investigate, to assess or develop, and to implement an effective corrosion stain remover in the Navy with the focus of reducing both maintenance costs and time.

This study describes the functionalization of a hybrid sol-gel polymeric coating with MOLY or ZAPP corrosion inhibitors and viable endospores of Bacillus licheniformis isolate (B6).

Jerrycans made of a high density polyethylene (HDPE) were filled with E85 and biodiesel and then exposed to temperatures of 20 °C (68°F) and 40 °C(104°F) for 5 years to study the interaction between HDPE and permeation barriers.

This paper will be dedicated to the corrosion resistance of roll-bonded UNS N06625 and N08825 clad materials.

A case history of a large diameter pipeline with fusion bonded epoxy coating that experienced AC corrosion within six (6) years while a similar 67-year-old pipeline with coal tar enamel coating experienced none.

Acrylic based thermal insulative coating (TIC) was compared to one-component and two-component epoxy TICs. Adhesion, hardness, tensile strength, water absorption, water fog resistance, and other tests were performed.
