1. - OBJECTIVE

The following specification gives the basic requirements for the supply of one “SWAGING AND EXPANSION MACHINE” for ends of steel pipe, 2 3/8” – 13 3/8”.

2. - PIPE SPECIFICATIONS

Pipes to be process are:

· Seamless pipes.

· Steel : All API grades

· Diameter and thickness and maximum hook due to swaging: See appendix 1.

· Main length: the minimum length of the pipe is 3 meters (10’).

· Maximum of straightness:

Maximum bending: 2.0 mm/m

Maximum deviation from the linear

Straight lines over the total length:10 mm

· Maximum difference between minimum and maximum diameter at the same end:

Maximum difference in outside in the not swaged area: +/- 1% of nominal OD

Maximum difference in outside in the swaged area: See APPENDIX 1.

· Hooked end:

Maximum hooked end 1.0 mm to 3.0 mm

· Surface condition: as rolled and quenched and tempered.

· Wall Thickness deviation: Average Wall thickness +/- 12.5%.

· Diameter deviation: Nominal diameter +1.0% - 0.5%.

3. - DESCRIPTION OF REQUIREMENTS, OPERATION

3.1 BASIC EQUIPMENT REQUIREMENT:

· Max swage length: 120mm.

· Equipment set up is easily accomplished for different pipe diameters.

· Master dies for swaging and expanse are “unit assembled”, thus facilitating the changeover process from swaging to expanse or vice versa.

· Centering and leveling of pipe as well as height adjustment is easily accomplished from either side of the machine.

· Speed and pressure of the hydraulic cylinder is also easily adjustable from high to low pressure.

3.2 Layout Swaging and Expansion Machine

3.3 GENERAL DESCRIPTION OF THE SWAGING AND EXPANSION MACHINE

The swaging and expansion machine consists of: A pipe handling unit, expansion master set unit, swage master set unit, main hydraulic cylinder for expansion and swaging, power pack with working pressure 180 – 300 bars and operator control panel. The pipe feed table is adjustable for various diameters of pipe.

Electrical requirements: 440/3/60 VAC, to supply the main induction motor and hydraulic unit. The expansion or swaging cycle is completed by a PLC program.

4. TECHNICAL SPECIFICATION AND SCOPE OF SUPPLY

The swaging and expansion machine consists of the following components:

· One operator control console.

· One hydraulic unit.

· Two sets of swaging dies for 4 sizes of pipe.

· Two sets of expansion dies for 4 sizes of pipe.

· One pipe handling unit.

· One set of master swaging dies.

· One set of master expansion dies.

· Complete information of all devices including:

a) Operating Manual.

b) Maintenance Manual.

c) Electrical Schematics.

d) Electronic Circuit Drawings of all electronics boards.

e) Wiring List and terminal blocks diagram.

Note: Additional die sizes are priced separately.

5. SPECIFICATIONS FOR THE SWAGING AND EXPANSION MACHINE.

I. SWAGE and Expanse Pressure

Description:

swaging machine

Range……………………4 ½” to 13 3/8” Diameter pipe (For expanse/ Upset)

Range……………………2 3/8” to 13 3/8” Diameter pipe (For Swaging)

Horizontal press………...380 - 500 Tons

Hold Down Press……….180 - 200 Tons

Pipe handling…………….Included

II. Cycle Time:

Total cycle time of the line is 50 – 80 seconds per pipe depending on diameter.

Pipe to pipe handling time is 15 – 25 seconds depending on pipe diameter and length.

The cycle time of the swaging machine is less than 45 - 55 seconds

The cycle time of 60 - 80 seconds consist of the following item:

Kick – in to the swaging line (transfer time)

Forwarding for the swaging machine (Pipe in-feed)

Pipe centering, swaging (swaging time)

Moving back (Pipe out-feed)

Kick – out of the pipe from swaging line (transfer time)

III. Equipped with:

Operator control panel

100 HP, Electric skid mounted hydraulic unit

3000 – 4500psi pressure

Auto stroke adjustment

440/3/60 electrics (380/3/50 also available)

The emergency stop button shall be easily accessible by the operator to stop all the movement of the machine. The button shall be installed on the control panel of the machine.

· Covers

Rotating components such as motor, shafts, rollers, and the other rotating

components shall be covered in order to prevent operator from touching those

components.

· Signs

All sharp places, which my hurt or injure operators by movement or both

machine and operator, shall be covered or painted clearly for operator to see.

6. TECHNICAL INFORMATION AND DOCUMENTATION

· Manufacturer shall provide 2 sets of operation, maintenance and trouble shooting manuals in English.

· All system software shall be documented.

· The proposal shall clearly specify the limits of its scope.

· Assembly drawings and sub assembly drawing will be provided for wearing part identification and ordering.

· All final drawings will be issued in paper ( 2 copies) and Electronic Auto CAD files. All the documents shall be issued in MS office format. All documents will be submitted between 2 weeks after test and commissioning machine.

7. PRELIMINARY RECEPTION TEST

1. The swaging machine will be tested before shipment.

2. Swaging test shall be done on different samples.

The sizes of the test pipe may change in the range of APPENDIX 1.

3. Full security and electrical / electronics protection tests shall be performed.

4. Only after satisfactorily fulfilling these tests will the unit be allowed to ship.

8. FINAL TESTING

Several “good” ends of different pipe sizes shall be swaged in the plant before the machine will be allowed to ship and before the test documentation will be prepared justifying the performance of the unit.

9. COMMISSSIONING AND TRANING

If desired, classroom and floor training can be done along with production testing and

commissioning of the machine.

APPENDIX 1

Figure 1 shows the schematic view of Tenaris BLUE. Table 1 shows the dimensions of the swaged ends of Tenaris BLUE.

Figure 2 shows the schematic view of NJO. Table 2 shows the dimensions of the swaged ends of NJO Ends.

Figure 3 shows the schematic view of Expansion PUNCH NJO BOX CONNECTION. Table 3 shows the dimensions of swaged ends of expansion Punch Box Ends.

Values in “PIPE DIMENSIONS” and “SWAGED END DIMENSIONS” are for reference purposes for the supplier. Values in the “Length and Weight of Swaged end” are to be taken into consideration for the induction heating system. The lengths and the weights of the stress relieving are stated in the “Stress Relief”, which are the most important figures.
