'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.
