EPC
GPT, a division of EnPro Industries, is the world’s leading manufacturer of critical pipeline sealing
and electrical isolation products. With a focus on safety, performance and reliability, we employ advanced engineering and manufacturing processes to meet the challenging demands of the oil and gas, water/wastewater, and construction and infrastructure industries.
With a global production, distribution and support network, we are positioned to meet our customers’ needs with unprecedented responsiveness and expertise.
Safety is the foundational objective of everything we do at GPT.
We've been selected by EH&S magazine three times as "The Safest Company in America". The only company ever to have done so.
Quality and compliance are a top priority for EPC applications. Compliance with international regulatory standards are essential for risk management, and employing durable, high-performance and precisely engineered solutions is imperative to meeting these standards and preventing contamination.
GPT assists in this critically important task with sealing and corrosion prevention products that conform to the highest international regulatory standards, including:
