Equipments for assembly
Crowbar
DN 60 to 125
Protect the socket with a piece of hard wood.
Sockets
DN 80 to 300 - Insertion machine
Recommended solution to assemble fittings.
Mechanical winches
DN 150 and over
Practical solution when access is difficult.
Use one or more winches depending on the DN.
| DN | Nbr of winches |
|---|---|
| 150 to 300 | 1 T516 (2.5 tons) |
| 350 to 600 | 1 T532 (5 tons) |
| 700 to 1200 | 2 T532 (2 x 5 tons) |
| 1400 to 2000 | 3 T532 (3 x 5 tons) +3 pulleys |
DN 500 to 2000
DN 500 to 1200: 3 TIRFOR 532 winches at 120°, 3 shackles and 6 wire ropes.
DN 1400 to 1800: 3 TIRFOR 532 winches at 120°, 6 wire ropes, 6 shackles, 3 pulley blocks.
Ratchet winch
DN 80 and over
REMA, PUL-LIFT YALE type ratchet winch with textile straps with looped ends.
| DN | Nbr of ratchet winches |
|---|---|
| 80 to 300 | 1 ( 1.5 tons) |
| 350 to 800 | 3 (3.5 tons) |
| 900 to 1200 | 2 (6 tons) ou 3 (3 tons) |
| 1400 to 2000 | 3 ( 6 tons) |
Cutting pipes
Check the outer diameter. Before cutting, use a circumference tape to check that the OD measured is less than OD + 1 mm.
| DN | DE mm | DN | DE mm | DN | DE mm | DN | DE mm |
|---|---|---|---|---|---|---|---|
| 60 | 77 | 250 | 274 | 600 | 635 | 1200 | 1255 |
| 80 | 98 | 300 | 326 | 700 | 738 | 1400 | 1462 |
| 100 | 118 | 350 | 378 | 800 | 842 | 1500 | 1565 |
| 125 | 144 | 400 | 429 | 900 | 945 | 1600 | 1668 |
| 150 | 17 | 450 | 480 | 1000 | 1048 | 1800 | 1857 |
| 200 | 222 | 500 | 532 | 1100 | 1151 | 2000 | 2082 |
DN ≤ 300: preferably, cut at a distance of less than 4 m from the pipe spigot.
DN > 300: preferably, cut the calibrated pipes specified in the order and identified by metal grey painted rings on the socket edges.
Mark
Mark the cutting plane perpendicular to the pipe axis.
Cut
- For DN 60 to 700
Use a cut off machine, for example.
- For DN 800 to 2000
Use a pneumatic cross cut saw (e.g. FEIN) which, with an adaptation, can produce the chamfer at the same time.
Fettle or chamfer
For EXPRESS mechanical joints, collar, fettle the cut edges with an angle grinder.
For STANDARD, STANDARD Vi, UNIVERSAL, etc. automatic joints redo the chamfer with an angle grinder to avoid damaging the joint.
| DN | m (mm) | n (mm) |
|---|---|---|
| 60 to 600 | 9 | 3 |
| 700 to 1200 | 15 | 5 |
| 1400 to 1600 | 20 | 7 |
| 1800 to 2000 | 23 | 8 |
Redo the coating
Recoat the edge exposed by the cut and the chamfer.
For the traditional black coating:
- INERTOL BS10 (1 kg : Ref. 281276 ; 5 kg : Ref 281275)
For NATURAL coating:
- EUROKOTE 438 (1 kg: Ref. 158255)
- AQUACOAT (0.75 kg : Ref. 240991)
