Pipe Welding, Fabrication & Installation in One Booking
Grana Works gives you one point of contact for pipework: supply of pipe, tube and fittings, workshop fabrication of spools, and installation, tie-ins and repairs on site. The welding is carried out by experienced specialist welding partners and managed by us, so you deal with one person from quote to handover.
We work for builders, mechanical and civil contractors, plant and facility managers, and food, beverage and industrial sites across Greater Sydney.
Pressure & Process Pipe Welding: Carbon Steel and Stainless Steel
- Carbon steel pipe welding for process, utility and plant pipework
- Stainless steel pipe welding in the grade your drawings specify
- Pipe spool fabrication in the workshop, marked and delivered to site
- On-site installation, tie-ins, modifications and repairs, including during shutdowns
- Pipe supports, brackets and frames from our welding & fabrication team
- Supply of pipe, fittings and flanges to your specification
Pressure Pipe Standards and Paperwork
In Australia, pressure piping is commonly specified to AS 4041, with welding procedures and welders qualified to standards such as AS/NZS 3992 or ASME Section IX. Your engineer or principal sets the requirement. Tell us the standard, pressure class, material, any NDT and pressure testing, and the documents you need when you request a quote. We will confirm which specialist partner can meet them, and what they can provide, before you commit.
Stainless Steel Sanitary Tube Welding: Supply, Fabricate, Install
Sanitary (hygienic) tube carries product, so the inside of every weld matters. Lines for food, beverage, brewery, dairy and similar processes need smooth, fully penetrated welds with no crevices, and runs that drain and clean properly.
- Supply of stainless sanitary tube and fittings: bends, tees, reducers, ferrules and clamp fittings
- Fabrication of tube spools, manifolds and process line sections
- On-site installation, modifications and repairs to existing lines
- Cleaning-in-place (CIP), product transfer and utility lines
- Tube supports and hangers set out for drainage and access
Tube grade, internal finish and inspection are set by your specification. Tell us what you need and we will confirm the process before you commit.
Purge Welding & Orbital Welding Sydney
Purge welding means filling the inside of a pipe or tube with an inert gas, usually argon, while the root is welded. Without it, oxygen attacks the back of a stainless weld and leaves a rough, oxidised root (often called “sugaring”) that can corrode and trap product. Purging uses dams, plugs, tape or inflatable bladders to hold the gas, and an oxygen monitor to check the level before welding starts.
Orbital welding is mechanised TIG welding where the torch travels around the tube in a fixed head, giving consistent, repeatable welds on thin-wall stainless tube. If your specification calls for orbital welding, tell us the tube sizes and requirements and we will confirm whether it can be provided for your job, or whether manual TIG with a back-purge suits.

How a Pipe Welding Job Runs
- 1. Enquiry – send drawings, isometrics or photos, the material and sizes, the suburb and your timeframe
- 2. Review – we check the specification, standards, access, shutdown windows and hot-work requirements
- 3. Written quote – supply, fabrication, installation and documents, itemised
- 4. Fabrication – spools and sections made in the workshop where possible
- 5. Install and weld – on site, with hot-work permits and fire watch as the site requires
- 6. Handover – photos and the records your job asked for at quote stage
What Affects the Price of Pipe Welding
- Material and grade (carbon steel or stainless), pipe or tube size and wall thickness
- Number of joints, fittings and spools
- Standards, procedures, NDT and pressure testing required
- Purging, orbital welding and internal finish requirements
- Workshop or on-site welding, access, and shutdown or after-hours windows
- Supply of materials, or free-issue materials from you
Safety & Hot Work
Pipe welding on site is hot work, often in live plants or tight spaces. We plan it around your site’s permits, with screens and extinguishers on hand and a fire watch after welding stops. Grana Works organises and manages the welding, including through trusted specialist partners.
