Wear parts for the refinery and Seveso plant around Gothenburg
Seveso means the measurement runs whether or not the spare is in your store, so it is not a reserve — it is a stock decision with a deadline. On shukchok the price and the grade are there before you ask.


Your rhythm on site
An analyser train that never stops does not consume analysers
One refinery here processes around 6 million tonnes of crude a year. A second runs with more than 200 specialists in 24/7 operation alongside a biorefinery of roughly 200,000 tonnes a year. Two of those sites are registered Seveso establishments, and Seveso means monitoring that is legally required, continuous and audited.
What it eats is coolers, PTFE elements, water separators, hose and fittings, on an interval you know and a supplier usually does not. And that interval does not move because a quotation is slow.
So the selection happens before the conversation. Grade and operating limits stand in a table at the article, and the full-text search reaches into that table — a stainless grade or a fluoroelastomer returns parts.
- Grade and operating limits in a table at all 114 articles, the same table in eight languages
- Net prices without an account, so a stock decision needs no phone call
- Signed in, the article page shows when this exact element was last ordered
Preem accounts for 80 percent of Swedish and 30 percent of Nordic refinery capacity.

What the marketplace changes
A refinery buyer asks about papers first — and that shelf is open
shukchok is an open marketplace for industrial goods, and the answer hangs on that: behind that question sit two shelves that separate cleanly. The first is the running operational demand, chosen on grade, operating limit and price. The second is certified demand — a works certificate to EN 10204, a calibration record, an ATEX or PED category at the article — chosen on paperwork and a named contact who stands behind it.
Two supplier landscapes sit behind those shelves, which is why a marketplace carries them and a single range cannot. Certified manufacturers attach here, hold their documents as article metadata and deliver through the same basket. Where your rules call for a certificate, the supplier you would write to anyway is invited to list, free of charge.
- The operational shelf works today: grade, limits and price at the position
- Both names stand at the position — who made it and who supplies it; the platform invoices
- Listing without a listing fee, a monthly fee or a manual release
The numbers behind it
Four plant types, and what each of them takes from the basket
| Plant type | Order of magnitude | What it consumes here |
|---|---|---|
| Crude oil refinery under Seveso obligations | around 6 million t of crude a year | Sample conditioning, seals, strainers, valves |
| Refinery with an attached biorefinery | more than 200 specialists in 24/7 operation; biorefinery around 200,000 t a year | Gas coolers, filter elements, fittings |
| Waste-fired combined heat and power | a third of regional district heat; precipitator, wet scrubbing, catalyst | Water separators, PTFE elements, steam fittings |
| Treatment works | the load of 790,000 inhabitants | Seals, sight glasses, pipe connectors |

Two ways in
Search by grade, not by category name
The full-text search reaches into the specification table, so a stainless grade or an elastomer returns parts. And if you hold the certificates: the second shelf is open and costs nothing.
