Bunch Projects
Pressure piping fabrication and installation with disciplined quality control
Bunch fabricates and installs pressure piping for upstream, midstream, and industrial projects across Western Canada.
Shop and field piping across Western Canada
Bunch has been executing pressure piping work since 1981, supporting upstream, midstream, and industrial projects across Western Canada. Our teams deliver shop fabrication and field installation for greenfield and brownfield scopes, with strong controls for safety, quality, traceability, testing, and turnover documentation.
We maintain more than 50 ABSA-registered procedures for welding and bonding and routinely fabricate more than 300,000 Factored Diameter Inches per year.
Materials
Carbon & Alloy Steel
Carbon steel, low-temperature carbon steel, chrome-moly, and duplex stainless steel for high-pressure, high-temperature, and cryogenic service.
Stainless Steel
Austenitic and duplex stainless steel with dedicated handling, dedicated tooling, and purge welding procedures to maintain material integrity.
HDPE & FRP
High-density polyethylene and fiberglass-reinforced plastic using registered bonding procedures for corrosive service where metallic systems are not suitable.
Automation and Mechanized Welding
Bunch uses automated pipe profiling, LJ pipe turners, pipe positioners, Miller RMD, wire-feed welding processes, and Submerged Arc Welding to improve productivity, repeatability, fit-up, and weld quality. These tools support efficient fabrication across repeatable spool work, larger-diameter pipe, and higher-deposition applications.
For clients running high-volume piping scopes, mechanized welding allows Bunch to maintain consistent quality and production rates that manual processes cannot match at scale. The result is competitive throughput with reliable dimensional control and weld quality.
