WPC100M: A Proven Field Joint Coating with Decades of Reliability



For more than 30 years, WPC100M has been a trusted field joint coating—particularly in offshore applications. Its long-standing track record speaks for itself, making it a familiar and reliable solution for contractors and operators around the world.

One of the key advantages of WPC100M is its butyl mastic sealant, which makes the system extremely forgiving when it comes to surface preparation. Unlike many onshore coating systems, WPC100M does not require an anchor pattern to perform effectively. While it is widely recognized for offshore use, it’s worth noting that WPC100M is also commonly and successfully used in onshore applications.

From a performance standpoint, WPC100M offers impressive temperature capabilities. It is rated for service temperatures up to 212°F when applied over insulated or concrete-coated pipelines, and up to 176°F when in direct contact with soil or the ocean floor. These properties also allow WPC100M to function effectively as a jacket continuation, adding to its versatility in the field.

WPC100M is available in 11", 17", 24", and 34" widths, with custom sizes also available. This flexibility allows it to accommodate a wide range of pipe diameters and project requirements. Combined with a **rapid installation time—often just a few minutes per joint depending on pipe size—**WPC100M helps keep projects moving efficiently without sacrificing performance.

Compatibility is another strong point. WPC100M works seamlessly with nearly all commonly used factory-applied coatings, including polypropylene, making it easy to integrate into existing pipeline coating systems.

With decades of proven performance, fast installation, and broad compatibility, WPC100M remains an excellent choice for a wide range of field joint coating applications—both offshore and onshore.
