customer’s requirement.
Technique specification:
First, install the locks on the connection section of two pipes,
screw the short bolt, then push the locks to the spigot end and
socket end separately,adjust the bolt hole place of long bolt on
the spigot end and socket end, make sure the holes on two sides are
concentric, screw the long bolt, fasten the bolt on socket end
first, then the spigot end, at last fasten all the short bolts.

Usage:
Much of the production of ductile iron is in the form of ductile
cast iron pipe, used for water and sewer lines. Ductile cast iron
pipe is stronger and easier to tap, requires less support and
provides greater flow area compared with pipes made from other
materials like PVC, concrete, polyethylene or steel. Ductile Iron
Pipe is the most widely-used pipeline product in water supply and
water drain/sewage projects.
Our advantages:
There are lots of qualified managers and technicians, and a
well-trained team of after-sales service, which provides all
services of manufacture, package, transportation and installation.
We are looking forward to cooperating with friends from abroad and
home creating a brighter future.
