6. ASSEMBLY
WARNING!
Risk of injury from improper assembly!
• Installation must only be carried out by authorized technicians and
with the appropriate tools!
• Secure system from unintentional activation.
6.1. Welding in the pipe connection
NOTE!
Damage to the welding ends!
• Remove end protection just before welding.
Leak due to damaged sealing contour!
• To ensure the sealing function, protect the sealing contour during
installation, welding and cleaning procedures.
Leak due to damaged seal!
• It is essential to remove the seal before welding and protect it
from dust, flying sparks and other influences!
Before welding:
→
Connect the parts positively in a protective gas shield.

→
For type BBS-03: Unscrew pipe connection!
Pull union nut on the liner side over the area to be welded onto
the pipe part to be welded on.
Welding
We recommend welding the connections using orbital welding
machines.
→
Always supply the weld with an inert gas.
→
Always form root seam welds.
→
Carefully clean welded joint.
→
Manual welding is possible. In doing so, use a higher-alloy filler
metal than the base material of the connection.
After welding:
When cleaning the weld seam by grinding or acid cleaning, observe
the following before assembling the connection:
• Carefully remove all grinding dust and acid-cleaning residue.
• Do not damage the label.
• There must be no material abrasion on the sealing edges. Material
abrasion will result in sharp-edged sealing contours and a damaged
seal.
• Check sealing contour for damage.
We recommend preparing a welding report.
6.2. Installing the seal
NOTE!
Damage to the EPDM and FEP seal!
• Sealing contours and contact areas must be free of contaminants.
• Do not use any pointed metallic objects.
• Never install FEP seals by force – e.g. by kinking. Even the slight-
est damage will result in leaks!
Damaged seals must be replaced!
→
Remove protective caps from sealing contours (protective caps
only for small delivery quantities or per order)
Type BBS-03, BBS-05 and BBS-06:
→
Insert O-ring before assembling the connection element into the
threaded connection or liner.
EPDM seals: Do not install using grease or oil!
If required, glycerin can be used as an installation aid.
FEP seals: Install by lubricating the surface with silicone grease
(FDA-compliant).
O-ring must be located firmly and tightly in the designated groove and
must not protrude into the pipe connection.

Type BBS-25:
→
Insert clamp seal into the threaded connection before screwing the
connection element together.
EPDM seals: Do not install using grease or oil!
If required, glycerin can be used as an installation aid.
Clamp seal must be located centrically and firmly and tightly in the
designated groove and must not protrude into the pipe connection.
6.3. Installing the pipe connection
→
Ensure that the seal is located correctly in the sealing contour.
→
Assemble both connection parts so that they are in alignment
(concentric deviation and angular offset of the pipe ends
max. +/–0.5 % of the outer pipe diameter)
Type BBS-03
→
Pull union nut over the liner.
→
We recommend lubricating the thread with suitable grease.
→
Manually turn union nut clockwise on the threaded connection.
Ensure that the connection turns freely, do not use force.
→
Tighten union nut using a suitable tool.
We recommend using flanges from DN 40.
Type BBS-06
→
Insert hexagon bolts through the screw holes in the flange.
→
Push circlip over the ends of the bolts.
→
Turn nuts on to the bolt threads, tighten by hand.
→
Tighten bolts crosswise using a suitable tool until flange sheets are
firmly situated one on top of the other.
Type BBS-05 and BBS-25
NOTE!
Damage to the connection element!
• Do not use any tools to install the clamp.
→
Manually place clamp over the connection.
→
Insert clamp screw into the designated slot, but do not use force.
→
Check that the clamp is seated correctly.
→
Carefully and evenly tighten the wing nut by hand until both pipe
components are firmly situated one on top of the other.
