Hot Dipped Steel Conduits
 

 

GI (ISI)

'VIMCO' quality steel conduits, confirm to IS 9537 Part II with Medium and High Protection, with ISI Mark.
   


'VIMCO' pipes are manufactured, from tested raw material, on fully automatic plant by High Frequency Induction Welding System which ensures perfect welding, to ease wire pulling.
   


The welded area is as strong as pipe's steel itself, hence any kind of bending job can be carried out without any chance of opening of the seam.
   
'VIMCO' trademark along with ISI is embossed on every length.
   
Threading
Threading is done on automatic threading machine having Lanco Chaser which maintains uniformity on length of the threading on major and inner diameter and the pitch of the threads.
 
Protection
Inner and outer surface is treated with special phosphating process.
Medium Protection Coating of the pipe, with Blank Stove Enamel, is done by dipping process to ensure proper coating inside and outside of the pipe. The pipes are baked in an Automatic Electric Oven for requisite hardening of paint and gloss finish on the pipe.
High Protection Coating of pipes i.e., Hot Dipped Galvanizing in done by automatic galvanizing plant. The zinc coating inside and outside is maintained in accordance with IS 4736/1986.
 
Quality Control
Raw material is tested in our lab before taking it to process. The finished pipes are tested for dimensions, Band Test, Screw Thread Test, Flattening Test, and compression Test before taking to final process, thereby ensuring the best to the ultimate user.
