Bins, hoppers, pressure piping and pipe racks – one fabricator for the plant
Bulk-handling bins and hoppers, transfer chutes, pressure pipe spools and the pipe racks that carry them are usually bought from different shops – and the interfaces between them cost time on site. World Steel fabricates them together, under one quality plan, one coating system and one shipping schedule.
- ISO 3834-2
- Certified welding quality comprehensive requirements
- EXC3 · CC3
- Structural execution class EN 1090-2 · AS/NZS 5131
- 3.1 / 3.2
- Material certificates EN 10204, heat-traceable
- 1 data book
- Per package ITP · NDT · tests · coating
One shop, one quality plan, fewer interfaces
A bin sits on a support structure, discharges through a hopper into a chute and is fed by pipes and conveyors carried on racks. When one fabricator makes all of it, the connection points, nozzle orientations, pipe supports and lifting lugs are checked against each other in the shop – not discovered at site.
World Steel works from your process and piping drawings, prepares shop drawings and spool isometrics, agrees an inspection and test plan with your inspector and delivers each package with a complete manufacturing data record.
Scope
Plant fabrication packages
Each package has its own page with scope, standards and quality steps.
Pressure piping spools
Carbon, low-temperature and stainless spools – welded, examined and pressure tested.

Pre-assembly
More work in the shop, less at site
Pipe rack modules can be shipped with pipe supports, cable tray brackets and walkways already installed, and bins with their hopper, outlet flange and platforms trial-fitted. Pipe spools are sized to fit in containers or on flat racks and are marked to match the isometrics, so site teams install instead of fabricate.
流程
From drawings to a documented delivery
- 1
Technical review
Drawings, specifications and codes are reviewed; queries are raised before material is ordered.
- 2
Shop drawings and isometrics
Tekla models for structures and bins; spool isometrics with weld numbers for piping.
- 3
Procedures and ITP
Welding procedures and welder qualifications for the code, NDT and test procedures, ITP with hold points.
- 4
Fabrication
Cutting, rolling, bending, fit-up and welding with heat numbers traced to each piece and spool.
- 5
Examination and tests
Visual, MT/PT, UT/RT to the specified extent; hydrostatic or pneumatic tests for piping; trial assembly.
- 6
Coating and dispatch
Blasting and painting or galvanising, marking, packing, data book and shipping.
FAQ
常见问题
Can World Steel fabricate structures and piping in one package?
Yes – structures, bins, chutes, pipe spools and pipe racks can be fabricated, coated and shipped together under one inspection and test plan.
Which codes do you fabricate piping to?
To the code in your specification – typically ASME B31.3 or B31.1, EN 13480 or AS 4041 – with welding procedures and welders qualified for that code.
Do you design the bins and hoppers?
We fabricate to your design or prepare the detailed design with our engineering team when the flow properties of the bulk material and the loads are known.
