FAQs

 

What size pressure vessel heads can you form?

Torispherical heads from 450 ID up to 4200 ID.
2:1 Semi Ellipsoidal heads from 1200 - 2500 diameter.
Hemisphere sizes confirmed upon application.

Do you have Quality Assurance?

The simple answer is no, however we have an internal system that covers the following: Material traceability, weld procedures, manufacturer’s data reports. Our reporting system has been designed in conjunction with key customer requirements, and has been developed to satisfy the requirements of AS 1210, AS 4458, PED; we also reference ASME VIII division I. Where further conformance is required we can recommend an experienced 3rd party inspector.

What thickness can we form?

Our thickness range is:
Heads between 450 - 800, when flanging is required, 3 mm - 8 mm
Heads between 800 -1200, when flanging is required 3 mm - 10 mm. 
Heads between 1200 & 3000, 6 mm - 25 mm 
Heads to 3000 to 4000, thickness confirmed on request.

What is the largest diameter you can dish?

On a dished and flanged end up to 4000mm diameter, although we have done slightly larger in heads formed from segments.

What is the largest size you can knuckle? 

We have formed a knuckle on a flat base that was 10500 mm in diameter from 4mm ss, the only thing restricting this size is the amount of work required to jig our machine.

What materials can you form heads from?

The common materials we use are stainless steel 316 & 304, mild steel grade 7-460,350 & 250, also duplex alloys. We also have formed Aluminium, Copper, Bisalloy, Inconel, Nickel Hastelloy.

Can you fabricate cones?

We can fabricate cones from light gauge materials, at a range of diameters, combining in-house fabricaiton with third party suppliers where brake pressing and folding are required

Can you flange cones?

We can flange cones at a range of diameters and degrees that can be confirmed upon application.
