Pipe

Grotnes expanders size pipe ends, metal bellows, slip joints and pipe fittings for use in the oil, gas, water and other industries.

These expanders form a cylindrical or spherical pipe connection, for a seal or formed thread. Sizing and forming pipe and tube (ends) is necessary in almost every industry, especially in oil and gas industries where required tolerances are important and can be achieved by Grotnes equipment.

• Expansion is a highly accurate and repeatable forming process with a shorter cycle time compared to other techniques.
• Grotnes expanders enable precise sizing and forming of profiles in a wide range of materials.
• Using an expander reduces material usage and significantly cuts machining time, with virtually no limits on the types of materials that can be formed or sized.
