Galvanizing is done according

to the EN 10240 standard

which requires the pipes to

meet various qualitative levels

of use, being produced by

hot-dipping in a completely

automised plant.

Galvanizing carried out by

Dalmine conforms to the A.1

level, qualitatively the highest

required by the European

standards.

The zinc used is an

electrolytic type with 99.995

percent purity. Pipes

galvanized in this manner are

suitable for carrying drinkable

water.

TenarisDalmine galvanized

tubes using the new ‘lead-free

galvanization’ technology are

conform to the EN 10240-A1

norm and the Ministry of

Health Decree 6 April 2004

objects used to distribute

water for human

consumption.

In civil and industrial

installations, it is necessary for

the color of the pipe to identify

the fluid carried. Dalmine has

created Thermo®: steel pipe,

coated with epoxy powder,

which means no painting on

site by the installer and even

easier and safer identification

of usage.

The coating is applied by

fusing epoxy powder onto the

surface of the grit-blasted pipe,

preheated to about 200°C.

The coating, with a minimum

thickness of 50 microns, gives a

working temperature of

between -10 to +110°C, and

has excellent adhesive

properties and resistance to

abrasion; allowing bending

with a standard portable

tool, with a mandrel having

a minimum bending radius

of 6 times the external

diameter of the pipe.

This particular type of

coating is produced on a

sheath extrusion line

producing a coating with

outstanding adherence and a

perfectly uniform thickness.

The product is able to satisfy

the demands of the most

particular users.

The coating offers a maximum

guarantee in terms of:

- high resistance to corrosion

- longer service life

- long life insulation (the

dielectric continuity test is

conducted in the factory at

25.000Volts - for bitumen

coated pipes the

corresponding test is at

10.000Volts).

- very high resistance

to nearby metal structures

- able to work in highly

corrosive environments

- easy cold bending at

the construction site

- easy to restore the coating

at joints.

The coating is applied on the

hot finished surface, after

blasting, when the pipes are

used for carrying gas, or for

water pipes on the galvani-

zed surface, according to the

EN 10240 A.1 standard, and

if requested with certificates.

For pipes to be used to

convey fluids for human

consumption the pipes, with

an external dimension of

88.9 ÷ 219.1 mm are coated

internally in a solvent-free

bicomponent epoxy resin,

with a minimum thickness of

250 microns, which ensures:

protection against corrosion

- spillage or loss of load

- a small reduction in the

internal diameter of the

pipe

- excellent adhesion to the

Pipes with external diameters

up to 219 mm are packed in

hexagonal bundles held by

four 1 1/4" wide steel straps,

with a grey seal bearing the

Dalmine logo. Each bundle is

made up according to the

following composition.

WATER AND NATURAL GAS PIPES

PIPES FOR PLUMBING AND CONDUIT

TemperatureThe working temperature

generally permitted runs from

-10 to + 110ºC.

Final inspectionBefore putting the pipes into

use it is normal practise to

carry out a hydraulic test at

1.5 times the nominally

allowed pressure for the type

of pipe chosen. Whenever

this test proves negative, in the

case of a leak which would

indicate some defect in the

pipe and not at the joint,

contact the Sales Department.

If there is any danger of

freezing, empty the plant.

PressureThe allowable pressures are

determined by the constructor

or end user, depending on the

kind of fluid, on the safety

coefficients, regulations,

norms or calculation codes,

which the installer must

satisfy.

BendingBending can be obtained by

standard, portable tooling

with mandrel having a

bending radius at least 6 times

the pipe O.D..

ThreadingManual screw-dies or

threading machines can be

used with equally good

results.

Machining requires the use of

dies with sharp

chasers, a good flow of

cutting oil and very good

alignment between the axis of

the die and the pipe.

Care should be taken in

choosing the cutting depth per

pass.

Threading couplingWater or gas tightness is

achieved by wrapping the

threads with hemp or tow

lint, and by using the

correct amount of sealing

product.

Alternatively, by carefully

wrapping a teflon band in the

direction of the screw thread,

taking care to maintain the

tension.

The steel couplings, or the

cast iron fittings, should be

reasonably tight when

screwing.

WeldingAn oxy-acetylene torch is

recommended with the

following settings.

Torch:gas flow in l/hr between

65 and 80 times the wall

thickness of the pipe in mm,

welding speed of 3.5 m/h on

average.

Welding wire:diameter not less than half

the pipe wall thickness, plus

1mm..

Preparatione of thepipe endsfor wall thicknesses not

greater than 3mm;square cut,

deburred.

for wall thicknesses greater

than 3mm; 45º bevel with a

grinder up to about half the

wall thickness.

Lay down

- Avoid completely any

contact with plaster and

mixed porous or materials,

e.g., mixtures of wood and

concrete, tile, etc.

- Prepare mortar and cement

with good quality concrete,

washed siliceous sand and

gravel, and clear, pure

water. Never use plaster or

anti freezing mixtures, as

the salts, such as chlorides

and sulphates, are

particularly corrosive

agents.

- Sink the pipe completely

into the mortar or concrete

mix, which should be thick

and homogenous, that is of

only one type, not mixed.

If there is any doubt

whatsoever that the above

suggestions have not been

carried out, do not hesitate to

wrap the pipe in tar paper, or

a similar product before

sinking the pipe into place.

Damage to the coating in the

welded area, or any accidental

damage occurring when

moving or laying down the

pipe can easily be repaired

with cold setting epoxy resins

of the same type in site with a

spatula or brush.

Dalmine Thermo®

Shortest possible distance

Pipes coated in extruded

polyethylene can be threaded

easily, without removing the

coating.

While using the

threading machine use the

appropriate pipe jaws,

however, in case of

emergency, the normal jaws

can be used, taking care to

hold the pipe firmly.

- A bending radius of up

tosix times the diameter

of the pipe can readily be

achieved using a chuck

with jaws of a sufficient

size.

- In the area surrounding

the joint the coating can

be repaired with

thermosetting bands,

cold- or hot-setting tape.

Before welding slide the sleeve

over the pipe end and position

it about 30 cm from the weld

area.

After welding clean the surface

well by sandblasting or

brushing.

Preheat the metal surface to

about 60º C and the place

where the sleeve will go to

about 40º C. Adjust the torch

to produce a soft, steady,

yellow flame.

Remove the sleeve's inner

protective release paper and

centre the sleeve over the joint,

allowing at least an 80 cm

overlap.

22

Istallation procedure

Beginning in the centre, heat

the sleeve, working out

towards the ends. Continue

until you see the mastic

beginning to come out of the

sleeve ends.

The coating may also be

restored using tape. There are

both single and double types

of tape available on the

market. The double tape

consists of tape for insulation

and for physical protection.

Other systems include using

primer.
