WA-solid block pipe leak repair clamp: Bolt Closing

* WA solid clamp is a special product used in applications with small diameter pipes.

  • * The clamp is made from a single metal block forging.
  • * WA-Solid block leak repair clamps are custom made for customer defined conditions.
Location Size Range (Inch) ANSI Class
Offshore / Onshore Solid Clamp 1" 18" 1500#

Seals may be slected according to application requirements

Repair clamps Girder ring restraint split bolted closing


WA-SBC Girder split clamps are suitable for high temperatures applications with pipe operational pressures up to 3700 psi.

Split Repair Sleeves can be equipped with hinge plates and lifting eyes to simplify field installation.

Seals are firmly kept in place with steel girder rings.

Hydrostatic test certificates are supplied with each delivery.


Repair Clamps elbow design - high pressure units.


WA-BC bend repair clamps: are used to repair pipeline bends and elbows. Higher friction between the fluid and pipe wall normally occurs at pipe bends.

Elbows are identified by curve, angle or radius definition. Elbow repair clamps are used to repair may be used most pipe sizes with high or low operational pressures.

Split repair elbow clamp halves are closed by bolts to form a high integrity pressure seal around the damaged or leaking pipe section.

Elbow repair clamps may be installed without shutting down the pipe line. Elbow repair clamps of various angles may be repaired.

Sealing is provided by elastomeric seals selected for compatibility with the pipeline fluid and temperature.

Split repair clamps elbow design are manufactured to the outer dimension of the elbows, they offer the best solution for pipe angle repair. 

Elbow leaks or weak or damaged elbow repair clamps are a solution for repairs at these vulnerable sections of the pipeline.

Elbow repair clamps are designed for ANSI Pressure classes 300-1500#. Design based on API 6H. Design calculation ASME Sec. VIII Div. I.

Flange Leak Repair Clamps - Stop leaks in flange gaskets


Flange leak repair clamps WA-FRC units are a permanent repair clamp for leaking flange gaskets under high operating pressure. The line remains in service during installation, no costly shutdowns.

No special flange surface preparation is required.

Flange repair clamps can be installed by company maintenance personnel.

There is no altering of existing flanges, other than cleaning the flange.

On scheduled shutdown maintenance the flange repair clamp can be removed and the gasket replaced. The unit may put back in service or held in stores for future repair.

Injection sockets are utilized to fully seal the compartment. In case of a small gap between the line flanges, gaskets can be installed for temporarily sealing prior too and during injection.

Product specification:

1. Body: ASTM A516 Gr.70flange-leak-repair
2. Stud Bolts: ASTM A193 Gr.. B7
3. Nuts: ASTM A194 Gr 2H
4. Gaskets: NBR

Design standards:

  • API SPEC 6H, Specification on End Closures, Connectors and Swivels
  • API SPEC 5L, Specification for Line Pipe

High Pressure pipe - Line Tapping

WA-HPT: High Pressure pipeline tapping allows a drill cut to be placed in the line while the line is continues in service.

The Tap is designed to ASTM standards-B31.4, .8, 3 and ASTM B31.1.

ANSI class pipes 150#, 300#, 600# and 900# are available.

Contact Westatlantic Tech Corp., with your requirements.

Repair Clamps WA-RC-RH units have a corrosion resistant 316L Stainless Steel housing









Repair clamps WA-RH stainless steel units repair leaking pipes with operational pressures up to 16 bars - 235 psi.

Available with NBR and Viton seals. Fits all america and international pipe sizes.

Design standards:

  • All metal parts: stainless steel AISI 304 or AISI316L.
  • Double band (two sections) with a working range of 20-22 mm depending on the diameter.
  • V gasket, steel reinforced to form the pressure chamber.
  • Standard NBR rubber gaskets.
  • Bridge plates are vulcanized into the rubber gasket.
  • Bolts are PTFE (Teflon™) coated to prevent galling.
  • No loose parts that may get lost during installation.
  • No special tools required: a simple wrench will do the job.
  • Under most circumstances the clamps can be installed. without releasing the pressure on the pipe.

The clamps can be used to repair the following pipe types:

  1. Ductile Iron (DI)                 - PE coated steel
  2. Cast Iron (CI)                      - PVC*
  3. Steel (St.)                           - GRP*
  4. Asbestos Cement (AC)        - PE*

If pipe repair clamps are to be used on plastic pipes, please always contact Westatlantic for more information regarding the
application and restrictions on these pipe types.
