We size it before we sell it
Every quotation carries the calculation behind it — flow, velocity, pressure budget and turndown. If the numbers say our product is wrong for your duty, the quotation says so too.

The company
We are the engineering company plants call when the filtration has already failed once.
Worldasatech began in 2006 with three engineers and one rolling machine. Nineteen years later we operate two manufacturing campuses, an in-house computational fluid dynamics group and an integrity laboratory that validates every rating we publish.
What has not changed is the starting point. Every project begins with the stream — its particle distribution, its chemistry, its worst credible day — and the equipment follows from that. It is the reason our quotations carry the calculation, and occasionally the reason they recommend against us.
Today that work runs in 62 countries: coalescers on North Sea platforms, sterile trains in licensed pharmaceutical plants, baghouses on continuously fired kilns, and purification loops on the first generation of green hydrogen assets.

Product platforms
Fourteen platforms.
One engineering standard.
Every platform is a family, not a part number — configured against your duty rather than selected from a shelf.
Industries served
Nineteen industries, each with a different definition of failure.
A fibre that is invisible in a water plant is a rejected batch in a paint shop. We specify against the consequence, not the category.
Why Worldasatech
Six reasons process engineers
keep the number.
None of these are differentiators on a brochure. They are the things that decide whether a filtration system still works in year seven.
02
Design and fabrication share a floor
The engineer who drew it can walk to the bay where it is being built. Constructability problems are solved in hours instead of through revision cycles.
03
Our own laboratory, not a subcontractor's
Multipass efficiency, aerosol carryover and integrity testing run on rigs we own. Validation is measured in days, not scheduled around someone else's queue.
04
One named engineer, start to finish
The same person owns your project from enquiry through commissioning, and remains reachable afterwards. There is no handover point where knowledge evaporates.
05
Documentation built for audit
Data books are indexed, traceable and delivered at dispatch — not assembled retrospectively when an inspector asks for them.
06
We service what others supplied
Relationships frequently start with an independent assessment of somebody else's installation. We will tell you if it is fine.
Interactive technology
Take the element apart before you specify it.
Rotate the assembly, explode it, section the housing or watch the flow path resolve from the annulus through the media into the core. Every component in the viewer maps to a real design decision — the pleat pitch, the core collapse rating, the fused end cap.
Outside-in flow
Unfiltered fluid enters the annulus, crosses the media, exits through the core.
Exploded assembly
Every seal interface and retention component, separated and labelled.
Cutaway view
The pressure envelope removed so the internal geometry reads clearly.

Manufacturing
Eight stages between raw plate and a code-stamped vessel.
Every stage produces a document. The vessel and its data book are built at the same time, not in sequence.
01
Material receipt & verification
Every plate, pipe and forging is verified against its EN 10204 3.1 or 3.2 certificate and positive material identification is performed before it enters the shop.
PMI by handheld XRF on 100% of alloy material. Heat numbers transcribed to the traceability record at receipt, not at dispatch.
02
Cutting & forming
CNC plasma and laser cutting, plate rolling to 80 mm, and hot and cold forming of dished heads under controlled procedure.
Cut edges dressed and inspected. Forming strain calculated and, where required, followed by solution annealing to restore properties.
03
Welding
SAW, GTAW, GMAW and SMAW under procedures qualified to ASME Section IX, executed by welders requalified every six months.
Weld maps issued before fitting. Consumable control by batch with heat-number recording on each joint.
04
Non-destructive testing
Radiographic, ultrasonic, magnetic particle and dye penetrant examination to the extent defined in the inspection test plan.
Level II and III certified technicians in-house. Film and scan data retained and issued with the data book.
05
Heat treatment
Post-weld heat treatment in a calibrated 6 m furnace with continuous chart recording, plus solution annealing for austenitic and duplex work.
Thermocouple placement per procedure. Charts reviewed and signed before release to the next stage.
06
Surface finishing
Shot blasting, pickling and passivation, mechanical polishing to 320 grit, and electropolishing to Ra ≤ 0.4 µm for sanitary work.
Surface roughness verified by profilometer on sanitary vessels and recorded against each internal surface.
07
Pressure & integrity testing
Hydrostatic proof at 1.5 times design pressure, helium leak testing where specified, and functional testing of all instrumentation.
Calibrated gauges with certificates traceable to national standards. Hold times recorded on the test certificate.
08
Assembly, FAT & dispatch
Skid assembly, wiring, factory acceptance testing on water, and preservation and packing for the destination and transit mode.
FAT witnessed by client or third party where required. Data book compiled, indexed and issued before dispatch.

In their words
What clients say when the shutdown is over.
They diagnosed in one meeting what we had been guessing at for eighteen months. The vessel was never going to work — no element would have fixed it.

Everyone else sent a proposal. Worldasatech sent a pilot skid and ran it through an entire algal bloom season before asking for the order.

One SEM analysis of a defect ended two years of argument between three suppliers. That is the kind of engineering we pay for.
