Pre-insulated piping and its advantages - Read an article by Mr. S Sankaran, Fellow-ASHRAE, published in the Airconditioning & Refrigeration Journal, Mar 2008 edition.

Seven Star has obtained Class 0 certification from a leading British laboratory for their pre insulated pipes. Samples of the pre insulated pipes with GI jackets were dispatched to the laboratory for testing under:

BS 476 - part 6 : Method of test for Fire Propogation of products and
BS 476 - part 7 : Method for Classification of the Surface Spread of flame of products 

The product was classified as Class 0 which is the highest possible classification as defined under Paragraph A13(b) of Approved Document B, ' Fire Safety', to the Building Regulations 2000 in the United Kingdom.
What this means in layman's terms is that the product is approved for use within buildings in the UK & Europe.

Seven Star introduces value added services to the HVAC Industry in general and for  piping systems in particular and has recently introduced a custom made pre insulated piping system. The excellent quality of  insulation achievable by the use of a pre insulated pipe is combined with the versatility of a grooved pipe jointing system to attain a high quality, high speed installation.

Welding is completely eliminated along with all of its associated problems.

The new system of piping is found to be extremely customer friendly especially for inaccessible areas such as shaft piping with multiple tapoffs. High rise buildings, hotel guest room tower blocks etc. will greatly benefit from such systems.

Accurate drillings of branch pipe diameters at predetermined locations on the main riser pipes are made with specialised machines, resulting  in a perfect finish, to accept grooved mechanical branchlets. The main pipe riser is then grooved at the ends for accepting grooved couplings and pre insulated at factory, leaving gaps at the the drilled portion and the grooved portion at the ends. The pre insulated pipes, branch pipes etc. are affixed with identification lables before despatch, for easy assembly & installation at site.
