Tube End Preparation

Cutting, Beveling and Facing of Tubes

As tube end preparation is such a critical step prior to welding, POLYSOUDE together with PROTEM offers a wide range of portable equipment for the precise machining of tubes and pipes, facilitating such operations as cutting, facing and beveling, thereby guaranteeing perfect and qualitative welds.

Cutting, Facing and Beveling:

There are various methods of cutting and preparing tube and pipe ends for further processes. In any cutting procedure, all aspects of obtaining a high quality weld must be considered:

  • No contamination of the inner diameter (including carbon contamination)
  • No heat affected zones
  • No surface damage

Protem’s innovative range of equipment includes: OD and ID mounted machines, beveling machines, orbital cutting machines, equipment for facing, squaring and counterboring... all of which maintain excellent accuracy and quality. The machines are suitable for preparations prior to welding work carried out using manual or automated processes. Typical joining applications include: tube to tube, tube to elbow, tube to flange, tube to tubesheet, waterwall cutout windows, membrane panels...

Polsoude’s cutting, facing and beveling technologies benefit from fast sequencing, versatility to perform on most materials and anti-contamination features.

    The OD mounted facing machine clamps onto the outside of the tube with clamping collets. No distortion of the tubes. Powered electrically or with cordless electric drive.
  • SL Series High purity - Facing and beveling machine + Contact us
    Specially designed to square tubes, fittings and tees for high purity applications (semi-conductor, pharmaceutical, clean rooms, food and beverage). Can be portable or bench mounted.

Beveling

Mobile machines for easy use on-site and in the workshop

These mobile beveling machines are lightweight, dependable and easy to use. The machines are equipped with tool-holder plates capable of carrying several tool-holders, which enable them to carry out welding preparation operations, producing a perfect land and appropriate counterbore wherever necessary. Their robust design also makes them perfectly suitable for machining thick-walled pipes.

The ID or OD clamped beveling machines are available with several options for standard or more challenging applications. ID tracking systems or elbow mandrel sets can easily be installed.

There is almost no limit in the use of our orbital beveling machines on tubes and pipes made of virtually all materials, of diameters ranging from 3 mm to 4267,2 mm OD (0,118” to 168”). Optional extension enables coverage of the full range of diameters of virtually all available pipes on the market.

Various motorisation options are available: electric, pneumatic or hydraulic.

What is orbital cutting:
When the replacement of a tube is necessary, the cut is made in upstream and downstream sections of the damaged tube. This maintenance operation can be done on-site and requires the best equipment for a perfect bevel, before performing welding operations.

What is facing:
Facing is creating a ‘land’ by making a flat surface on the pipe-end. Correct surfacing makes pipes easier to align. Our machines minimise the risk of contamination, as they create ‘chips’ in the form of a ribbon and not particles.
This process is particularly suited to High Purity applications, including semi-conductors, food processing, pharmaceuticals, clean rooms, etc.

What is beveling:
Beveling is a process, by which the joint is prepared, prior to welding.
In order to achieve a beveled surface for tube and pipe ends, the bevel machine can either be clamped onto the outside diameter OD or inner diameter ID of the pipe.
Chipping at the surface of the outer diameter, the cutting surface and the inner diameter is called respectively, beveling, facing and counterboring .
This machining is done by a tool bit, clamped into a toolholder and mounted on the chuck, which turns around the work piece.
