Pipe Fit (Offshore)™

Pipe Fit is to reinforce and seal the area for permanent restoration just by bolting the clamp on the pipeline in order to activate the sealing gaskets without shutting down the on-stream.
It can be seal welded to the line for solid permanent attachment.

Features:
• Sizes from1-1/2" to 56" API pipelines
• Pressure from ANSI 400 through ANSI 1500 pressure rating (higher pressures on request).
• Body material : Conforming by API 6H, A216 WCB/WCC and A516 Gr70 as standard
• Gasket Material: Buna-N (NBR) is standard and Viton as option or application (other elastomers on option)

• Stud and Nut material: ASTM A 193 Gr. B7 and ASTM A 194 Gr. 2H (M series for sour applications)
• Coating: zinc rich + Epoxy (other coating systems on option)
• Easily replaceable gaskets without special needed tools
• 100% leak test and Hydro test (1-1/2 working pressure) as well as assembly test on leaking pipeline (real operational practice for controlling the geometry and symmetric of the shells and bolting pattern)
• Regular, ultra and optional lengths (dimensional tables are available on downloads tap on website)
• SLFS ™(Superior Leak Free Sealing ): Stainless Steel welded heckle shape protection sheets to:
1. Quicker Sealing action in early installation
2. Safer constant sealing
3. High pressure resistance in fluid direct push
4. Easier gasket replacement in several use of part

• Annulus test port for grout or inhibitor injection
• Secured retained components before and during installation
• No need for hyperbaric welding

Pipe Tight™

Pipe Tight™ is a non-structural coupling for easy and safe end connection of pipes for oil, gas and petrochemical onshore and offshore pipelines with no especial pipe ends preparation.

Two sets of bolting are considered; radial and axial screws. They align two pipe ends together and compress the sealing gaskets respectively.
To withstand axial forces and end pull of high pressure it is recommended to be anchored (i.e. either it is fully welded on the line pipes on in-operation line with specific pressure or the line is axially supported by using Anchor Fit double set) welding is permitted weeks after seal proving interval.
Gasket material is selected compatible to your operating temperature, rate of corrosion and the product performance. NBR is standard, others are available upon request.


• It can be DRS™, DRB™ (double row circumferential bolts), and ultra long for offshore applications and when welding is not allowed or possible.
• Size range from 1-1/2" to 56".
• Lock nuts for high vibration applications.
• Body materials is according to API 5L/ASTM A106 or equivalent
• To reuse the part, gaskets have to be replacing with new set.
• Pipe Tight can be use for valve installation and other line modifications.

Flange Tight™

Single sided Pipe Tight welded to a flange for tie-in, abandonment, expansion or repeating jobs for non-welding locations.

Riser Tight™

Single sided DRB / DRS long Pipe Tight to connect offshore pipe to top side in platforms.

Swivel Mate flange™

Bolting aliment to ease sub sea pipeline joining flange connections e/w rotating retainer ring.



• Size variation from 2" up to 56".
• ANSI 600 and 900
• ASME compliant
• Marine coating and cathodic considerations.

Positioning Flange Connector ™

Featuring misalignment, unstressed compensation of pipeline in spool connection angel by ± 10° of full axial orientation e/w rotating ball design and metal integral repeatable sealing.


• Size variation from 2" up to 56".
• ANSI 600 and 900
• ASME compliant
• Marine coating and cathodic consideration
• It can be combined with a adaptor flange to connect offshore line to riser.

Box Fit™(Offshore)

To encapsulate flanges and fittings on topside from pipe to pipe or over clamp , to cover up the previous subsea clamp when has leak in close proximity and replacing the clamp with longer version or side installation is not feasible.
Box Fit is also suitable for dual size pipeline weld connection leak repair.

Custom Fit™(Offshore)

For irregular connections and fittings, eccentric connection, reducer, anode attachment and any kind of fitting or leak repair end closure can be fabricated with customized design.
