Industrial Services for Piping Construction

In piping construction, prefabrication and assembly determine schedules, weld quality and cost. Pipe spools must be cut to length, cleanly bevelled and prepared for welding — on site as well as in prefabrication.

HSOS supports prefabrication and assembly with machined pipe cutting, precise beveling for all common weld preparations, controlled preheating and post-weld heat treatment (PWHT) on thin- and thick-walled joints. Spark-free cold cutting without heat input is possible even in hazardous or live-plant areas.

Documentation to AD 2000, ASME and project-specific codes — audit-ready and traceable.

Challenges

  • Accurate cutting and beveling for weld-ready joint preparation
  • Tight schedules in prefabrication and site assembly
  • Controlled preheating and PWHT across varying wall thicknesses
  • Machining without sparks and heat input in live-plant areas
  • Traceable documentation per weld and component

Our experience

  • Machined pipe cutting and beveling from DN 25 to DN 600
  • Weld preparation (V, U, compound bevels) to WPS
  • Controlled preheating with resistance and induction techniques
  • Post-weld heat treatment (PWHT) to AD 2000 HP 7/1 and ASME PCC-2
  • Spark-free cold cutting in Ex and live-plant zones

FAQ

Do you work in prefabrication and on site?

Yes — pipe cutting, beveling, preheating and PWHT both in prefabrication and during on-site assembly.

Which pipe sizes do you handle?

Machined cutting and beveling typically from DN 25 to DN 600, larger diameters on request.

Can you cut without heat input?

Yes — spark-free cold cutting with no heat input, including Ex and live-plant areas.
