Abstract

The rehabilitation of pipeline coatings in the field is often done under circumstances that are quite different from those in a factory when a plant coating is applied. In the field, the presence of salts, sulfurs, high humidity, mosquitos, sand, wind, rain and moisture do not contribute to the creation of controlled ambient conditions for the proper application of a coating. Moreover NACE studies (1995) have proven that when applying coatings in the field there is a higher risk of coating failure due to improper surface preparation, application failures, adhesion problems and microbiological induced corrosion. In view of the fact that most coatings are not 100% impervious to moisture and gases, resulting in a higher risk for disbondment and osmosis, a perfect adhesion in the field is very important in order to reduce the risk of coating degradation over time.
The invention of so called non crystalline amorphous polymer coatings make it possible to reduce the influence of hazardous ambient conditions when rehabilitating coatings in the field. Low viscosity amorphous polymers coatings are usually made of non-crystalline polyolefins that have an initial adhesion to the substrate by so called Van Der Waals Forces. As a result of these van Der Waals Forces they usually adhere to many substrates without any intensive surface preparation and hence are easy to apply under difficult ambient conditions. As a result of the Van Der Waal adhesion mechanism and the low surface tension of the coating, continuous wetting of the pipeline substrate takes place and disbondment over time is unlikely, hence reducing the risk of future coating degradation.

He is Director of Lalita Infraprojects Pvt.Ltd who are manufacturer and applicator of Corrosion Resistant Organic Coating  like solvent free polyurethane , epoxy, glass flake epoxy, coal tar epoxy for oil, gas & water pipeline.
 
Dr. Buddhadeb Duari has done B. Tech (Hons) in Mechanical Engineering from I.I.T Kharagpur, MBA from Jamnalal Bajaj Institute of Management Studies and Ph.D (Engg) in Metallurgy and Material Engineering from Jadavpur University. He is a NACE Corrosion Specialist, Protective Coating Specialist from NACE International, Houston, USA and SSPC Protective Coating Specialist from SSPC, Pitsburgh, USA. He is a member of BIS (Bureau of Indian Standard) for CHD 20 (Chemical & Paint Division) and MTD 24 (Metallurgical Technical Division). He has more than 30 years experience on Corrosion, Coating and Cathodic Protection of Metals, Structure and Concrete. He has published more than 40 Technical Papers in reputed journals out of which 18 are International and Peer Reviewed Journals like MP Materials Performance, JPCL, Coating & Maintenance, Bulletin of Materials Science, Corrosion Management, IJLRST, IJEIT.
 
Dr Buddhadeb Duari is consultant to different Corrosion related projects.
JabelAli Extension, Dubai placed Cable Tray Support System with Siemens, Germany. These cable trays are to be coated as per DIN EN ISO 12944-1 with 80 micron hot dip galvanizing. Further the same is to be coated with 60 micron epoxy powder primer and 60 micron epoxy powder by electrostatic precipitation method. After coating is completed, investigation (through field inspection and laboratory testing) is carried out to find whether coating is done as per specification. For this purpose, the coated samples were investigated by microscope, Fourier transform infrared spectroscope. It would be interesting to mention that coating with only epoxy polyester powder is found.

Name: Qihua Miao (Alex Miao)
Title / Position:  Senior Technical Services Manager
Company:  Sherwin Williams (Shanghai) Ltd
​  
Alex Miao has been working as a Senior Technical Services Manager in Sherwin Williams (Shanghai) since Aug 2008. His role and responsibility are to lead the Technical Service Team to provide the high quality technical services for all projects, which not only involve the protective coating, marine coating, but also architectural coating in China and other Asia Pacific regions. The inspection activities ensure all the paint applications on the job sites to meet the technical specifications and other requirements. He is NACE certified inspector and the majority of his team members are NACE CIP Level 2. In the meantime, he and his experienced team assist the Sales, Marketing, R&D departments to open new segments such as Nuclear Power plants with the latest technology, and Oil & Gas industry with passive fireproofing protection  technology.  He  is  now  working  closely  with  all  the teams from various parties such as the owners, the contractor or sub-contractors in the Yamal Project for PFP applications
Many processes in the Oil and Gas Industries require high or low temperatures. So the insulations are needed not only for process efficiency, but also for the personnel safety. Corrosion Under Insulations (CUI) is one of the most costliest problems attacking the industry today. This presentation will review the evolution of insulation solutions available in the past, and include high durable and excellent adhesion performance characteristics with the substantial benefits this new Epoxy syntactic coating/insulation technology offers to the Industries.
Syntactic Epoxy Coating/Insulation is a solvent free epoxy thermal insulating barrier, providing an uncompromising solution for the Cryogenic Spill Protection (CSP) of steel structures in the most demanding environments with operating service temperature range from -103°F or -75°C to 300°F or 150°C. It has strong resistance to the following: moisture, alkali spillage, aliphatic solvents, petroleum solvents, impact, etc. It can be used alone where fire protection is not required. In the meantime, it has extensive track record in conjunction with PFP which has been successfully used on over 2000 major projects worldwide. In additional, with ever-tightening environmental restrictions in the world, it also offers a vital no VOC option for regulatory compliance.
This new Syntactic Epoxy Coating/Insulation has major advantages in thermal performance, durability, reducing the CUI, easy application and maintenance. In combination of Epoxy Intumescent Coatings, it enables to provide protection against cryogenic spill followed by a fire.
