Pipeline Flanged Ductile Iron Pipe Fittings Paint Coatings EN545 /
598 K9 Class
Flanged Ductile Iron Pipe:
Flanged ductile iron pipe with a range of DN80 to DN 2600.belongs
to Ductile iron pipeline systems, including pipes, fittings,
accessories and joints, consist of various materials.When used for
conveying water intended for human consumption, the materials in
contact with the water shall meet the relevant requirements of the
national standards or regulations in the country of use with
respect to effect on water quality.The lengths of flanged pipes
shall be as given. Other lengths are available by agreement between
the manufacturer and the purchaser.
Specifications:
1. Thickness of paint coatings
The dry film thickness of paint coatings shall be measured by one
of the three following methods:
- directly on the casting by means of suitable gauges, e.g. magnetic,
or by using a ‘wet film’ thickness gauge where a correlation
between wet film thickness and dry film thickness can be
demonstrated, or
- indirectly on a token which is attached to the casting before
coating and is used after coating to measure the dry film thickness
by mechanical means, e.g. micrometer, or by a weight method similar
to 6.7, or
- indirectly on a test plate made of steel or of ductile iron, which
is coated by the same process as the castings to be controlled.
For each casting to be controlled, at least three measurements
shall be taken (either on the casting or on the token or on a test
plate). The mean thickness is the average of all the measurements
taken and the local minimum thickness is the lowest value of all
the measurements taken. The manufacturer shall record the method
used in his documented FPC procedures.
2. Thickness of cement mortar lining
During manufacture, the thickness shall be measured on the freshly
applied lining by a spear having a diameter of 1,5 mm or less and
controlled on the finished hardened lining by means of a suitable
gauge, e.g. magnetic.
For pipes, the measurements shall be taken approximately 200 mm
from the end face. The manufacturer’s process control system shall
specify the frequency of this test.
Packing: in wooden box or pallet, or in bulk
Shipment: in bulk or container
Usage:
Ductile iron pipeline systems, including pipes, fittings,
accessories and joints, consist of various materials.When used for
conveying water intended for human consumption, the materials in
contact with the water shall meet the relevant requirements of the
national standards or regulations in the country of use with
respect to effect on water quality. When used under the conditions
for which they are designed, in permanent or in temporary contact
with water intended for human consumption, ductile iron pipes,
fittings and their joints shall not have detrimental effects on the
properties of that water for its intended use.
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.
