Marks Brothers - Pipe Coils for Internal Heating

Marks Brothers manufactures pipe coils for internal heating or cooling of vessels with continuous CNC-rolling and automatic orbital welding of seams. Each pipe is orbitally welded into the coil as it is rolled into a coil at the specified diameter and pitch. This process ensures x-ray quality welds, provides a consistent radius and pitch, dramatically reduces material waste, and saves significant labor costs compared to trimming and fitting pre-rolled pipes into a coil. Spot x-ray, 100% x-ray, hydrostatic testing, and documentation is provided based on specific job requirements.
