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.
