Manufacturing Capability
From pressure-vessel fabrication to complete on-site installation and commissioning of very large autoclave systems.
Project Reference: On-Site Manufactured 5.2 m × 10 m Autoclave
A recent YRPR project demonstrates our large-system capability: an autoclave with a working diameter of 5,200 mm and length of 10,000 mm, designed for a 400 °C design temperature and 1.6 MPa design pressure, manufactured and commissioned directly at the customer’s site.
Project Timeline
| Specification | Details |
|---|---|
| Design & procurement | One month of engineering; procurement of plates, heads and flange forgings; shell sections and flange heads welded and finish-machined, then transported to the customer site (approx. 4 months to site). |
| On-site shell fabrication | On-site shell fabrication and flange-to-shell welding, followed by hydrostatic testing (approx. 2 months). |
| Internal installation | Internal installation: insulation, air-guide device, cooler and heater installation (approx. 2 months). |
| External work | Door installation, air inlet / exhaust, drain lines and vacuum valve assemblies (approx. 1 month). |
| Electrical & control | Electrical and control system installation and on-site wiring (approx. 1 month). |
| Commissioning & acceptance | With power, water and gas in place: integrated commissioning and final acceptance (approx. 1 month), including the nitrogen source system. |
Three-dimensional design models are prepared for every project, and the complete pressure vessel is delivered with full documentation and acceptance records.
Our Facility
YRPR operates purpose-built manufacturing halls for pressure vessel fabrication, machining, assembly and integrated testing – supported by tooling for large-diameter shell sections, door assemblies and control-system integration.
