THE MAN GROUP

The modern facilities at Man Industries enable the

company to supply quality and flawless steel pipes. The

company has state-of-the-art Automated Roll Bending

Mill equipped with CNC and PLC controls, Internal and

External welding units, Cold Expander, Online Real Time

Radioscopy, Advanced CNC controlled hydrostatic

testing, Online X-Ray, Ultrasonic Testing Machines, etc.

All these facilities have earned the company approvals

from the clients such as Shell Global, Saudi Aramco,

Qatar Petroleum, Kuwait Oil Co., Bechtel, EIL, GAIL,

IOCL etc.

Quality has been the prime concern for the company for

any of the product it manufactures. To ensure that the

products are of utmost quality, Man Industries has

roped in the world's most advanced technology in this

highly specialized and high priority field. The latest, Pre

stressed three Roll Bending process from Haeusler is

being used to manufacture Line Pipes of improved

strength and toughness. In addition, the collaborators

have given a performance guarantee for the plant in

terms of production parameters and adherence to all

international standards of quality including API and

NACE.

Hot rolled plates with mill test certificates are received, inspected,

Ultrasonically tested and sorted at the receiving bay. The plate is

then milled to precise width and beveled for welding.

The In-feed conveyor transports the plate to CNC and PLC

controlled 3 Roll Bending Machine for rolling. Post bending is

carried out to make the required edge profile of the pipe and then the

pipe moves on conveyor for continuous welding. Longitudinal

seam of pipe is tacked and welded using Gas Metal Arc Welding

(GMAW) method. The pipe is then transported to the Internal

SA Welding area by conveyors.

The inner longitudinal seam is welded by using 3 wire SAW method

followed by external welding on the outer seam of the pipe. The Line

pipe is later transferred for washing to remove the scales after

which the pipe is passed through a real time radiography for flaw

detection in the weld.

The pipe is then delivered to Expander unit for cold expansion after

which the ends are bevelled by the end facing machine. This is

followed by Hydrostatic Testing and later Ultrasonic Testing,

Radiography, MPI as well as visual and dimensional inspections.

Painting and Stenciling is then carried out as per specifications.

* Depending on the diameter and thinkness of the line pipe produced in a year

Spiral Welded Pipes find various

applications and uses in the crude

oil/petrochemical transportation,

water supply, sewerage disposal,

construction industry & agriculture. To

meet the growing demand of pipes

meant for critical & non-critical

applications, Man Industries offers high

quality Spirally Welded Steel Pipes

conforming to international ly

accepted quality standards laid down

by the American Petroleum Institute

(API) and BS.

To manufacture high quality Spiral Welded Steel Pipes,

the company has availed of the latest and the most

advanced state-of-the-art technology. The plant located

at Anjar has two production lines for manufacturing

HSAW Line Pipes and both of them are independently

equipped with the latest equipment and auxiliaries to

meet critical specifications of the customers of varied

segments.

Hot rolled coils are the main raw material for the

production of welded Spiral Pipes. The coil is first

inspected for lamination, slivers or other surface

defects. It is then mounted on the Decoiler and is fed

through a series of rollers of Leveler followed by milling

of both the edges.

The beveled coil is fed by drive rollers to the Forming

Cage where the pipe is formed and then followed

immediately by inside and outside welding operations

(using 2 tandem wires each). The pipe is then been cut

to the required length and transferred to the End Facing

Machine for providing required bevel to the pipe ends.

The finished pipe is then subjected to destructive and

non-destructive testing as per relevant specifications

Grade Upto API 5L X 70

The FBE, 3LPE and 3PP coating systems are applied on a

single process line. The pipe is first heated to remove any

moisture present on the surface. It is then blast cleaned to

provide the required degree of roughness and inspected

for cleanliness. An acidic surface treatment can be done, if

required by the specification. The pipe is then heated by

electric induction and FBE is sprayed on the line pipe to

achieve the required thickness of this layer. Before the FBE

gels, the Co-polymer Adhesive is applied by extrusion

method followed by application of PE or PP Layer. The

coated pipe is then allowed to pass through a quenching

tunnel for cooling. Further inspection and cut back

removal takes place after the pipe is sufficiently cooled.

Pipe Diameter: 6” to 56”

Plant Capacity: 3,900,000 sq. m. per annum.

To protect the line pipes from corrosion and to enhance

its operational life, Man Industries offers various options

of coating systems to the choice of the customer as per

the end use of the pipe.

The coating is carried out using the latest technology

and proven raw materials.

The operation begins with the pipe being placed on the

rotator of the Shot Blasting Machine and the hose pipe

with a rotary turbine travels longitudinally inside the pipe

from one end to other centrifugally emitting the shots-grit

mixture with a high velocity to provide the required degree

of roughness to the internal surface of the pipe. The

metallic dust generated during the blast operation is

collected by an efficient dust collector.

The blast cleaned pipe is transferred to another rotator by

the means of hydraulic ejecting and receiving arms. The

boom carrying the rotary spray head is inserted inside the

pipe, which sprays the epoxy mixture uniformly on the

pipe inside surface from one end to other end. The travel

speed of the boom flow of epoxy mixture is adjusted to

meet the required thickness of the epoxy layer as per the

specification. The coating can be performed in single or

double layers depending on the thickness of coating.

The coated pipe is then rolled over the padded skid to the

curing chamber and finally to stenciling and

storage/dispatch section.

Pipes are coated internally to prevent

corrosion and to improve the product flow

characteristics. Man Industries offers coating

in the form of two part liquid epoxy system in

thickness range from 75 to 750 microns.

Pipe Diameter: 14” to 84” and above.

Plant Capacity: 2,900,000 sq. m. per annum.

The Coaltar Enamel Coating process first begins by the

pipe being externally shot blasted to the required standard.

A layer of coaltar primer is then immediately applied on the

shot blasted surface. This is applied online immediately

after the shot blasting.

The pipe is then transported to the coating booth by the

means of ejecting and receiving arms and intermediate

skid. In the application booth, as the pipe rotates over a

parabolic conveyer, the hot molten coaltar is made to fall

freely under gravity on the pipe surface with the fiber glass

inner and intermediate wraps wrapped simultaneously. As

the pipe exits the booth, it is covered with the last outer

wrap. Finally, the pipe is made to pass through a tunnel

having cold water sprayed on it continuously to cool the

coating. After cut back removal, the coated pipe is rolled

over a V-board for inspection, stenciling and dispatch.

Coaltar Enamel Coating is applied on pipes that

are used for both onshore as well as offshore

applications. Coaltar Enamel Coating is now

being used for over more than 50 years. The

coating is applied mostly on pipes that are

used in relatively swampy and damp soil

conditions and in offshore installations.

To prevent the corrosion of the pipe, an external cement

mortar coating is applied. The thickness of this coating is

generally 25-40 mm and the density of the concrete varies

from 2200 to 3400 Kg / m3.

Application of the cement mortar, by the impingement

/spinning method, can be done either from the top or from

the side of the pipe. Either batching or volumetric mixer

(depending on the project), can be used for mixing. After

application, the fresh cement mortar is then treated for

curing.

Pipe Diameter: 12” to 84”

Plant Capacity: 200,000 sq. m. (at 25 mm thickness)

per annum.

The internal cement coating is done mainly for

the water and the sewage pipelines to protect

them from corrosion and to enhance its life.

Pipe Diameter: 16” to 84”

Plant Capacity: 200,000 sq. m. (at 25 mm thickness)

Per annum.

The pipe is put on the rotators and a calculated quantity of

premixed cement is put in the pipe. The pipe is then rotated

at the required rpm and the cement mortar mixture thus

centrifugally sets on the inside surface of the pipe. To

enhance the life of the pipe, it is cured as per the standard

procedures.
