The world’s first dedicated pipe freezing company. Founded in 1972, still setting the standard today.
Bishop Pipe Freezing was founded by Cyril Bishop in Croydon, London in 1972. It was the world’s first dedicated pipe freezing company, and the techniques and standards Cyril helped establish are still the foundation of how the industry operates today.
More than 50 years on, we remain a specialist company. Pipe freezing, hot tapping, shrink fitting and related cryogenic services are what we do. Our team has a combined experience of over 125 years in the field.
