All deficiencies/ non-compliances found at…
Introduction The objective in applying anti-corrosion coatings is to provide a film which will give protection and/or decoration to the structure being applied. The variables which govern the success of any application and subsequent performance are: Surface preparation Film thickness of the paint system Methods of application Conditions during application Surface Preparation As detailed in…
Introduction Copper Pipes have high mechanical quality; however the sensitive material is delicate and will weaken under high pressure. Leak will start to happen when the Copper Pipe system is subjected to considerable vibrations. Performing Copper Pipe leak repairs for little estimations can be viably completed after the underneath repair methods. Surface Preparation of Affected…
If a leak happens on an underground pipe after the meter from the water main, it looks like you will have to plan for the repair works to be carried out. This can be done with repair putty compounds. 1. Check and Confirm the Pipe Routing You may still have the old drawing of the pipe routing. Check to…
Introduction Anti-corrosion coatings do not last forever. They age, weaken and deteriorate and eventually their useful life ends. The most common cause for premature anti-corrosion coating failure is insufficient care during the mixing, application and curing processes. Poor application technique can typically cause problems such as improper thickness, pinholes, sags, mud-cracking, and holidays. Inadequate surface…
Introduction There are a number of factors which must be considered when anti-corrosion coatings are applied. The major ones include: Condition of the substrate Temperature Relative humidity Weather conditions Condensation Ventilation Ultraviolet light (UV) 1. Condition of the Substrate The surface must be clean and free from dirt, dust, abrasive blast medium (if used), oil,…
Introduction Pipe weld joints are one of the weakest links within the piping system. Pipe leaks often occur around the weld joints due to various reasons. Some of the reasons include: Lack of fusion Corrosion at heat affected zone Crack (due to heat stress, solidification, hydrogen-induced) Porosity Contamination Inclusion of slag In order to arrest…
