Petrochemical Steel Structures
Petrochemical steel structures usually cover pipe racks, equipment frames, platforms, ladders and module supports, requiring coordination across disciplines, weld quality, fire and corrosion protection, and material traceability. Detailing, fabrication, inspection and export delivery can be provided; process design, pressure vessels and piping installation remain with the other project parties.
Applicable Scenarios
Pipe racks, equipment frames, platforms and structures in refinery, chemical and fertilizer units.
Reference project: the Nigeria refinery integration project (Dangote petrochemical and fertilizer complex), with a steel scope of about 12,000 tonnes covering detailing, fabrication and sea freight delivery.
Members & Services
Scope covers pipe racks, equipment frames, platforms, ladders, handrails, module supports and complex connection parts.
Cutting, drilling, welding, straightening, dimensional inspection and surface treatment are included; complex joints can go through manufacturability review first.
Fireproofing, Coating and Traceability
Fire and corrosion requirements are demanding in petrochemical plants, so members usually follow project coating or fireproofing specifications with controlled surface preparation.
Heat numbers, welding records and inspection documents are matched to member marks so they can be traced and accepted on site.
Delivery & Installation Support
Members are split for transport and lifting, with marking and packing aligned to the site erection sequence; overseas projects are mainly shipped by sea.
Installation support can cover member identification, erection sequencing, connection clarification and issue closure. Process design, pressure vessels and piping installation are outside this scope.
Frequently Asked Questions
How are pipe rack and equipment frame interfaces coordinated?
Equipment interfaces, levels and connection details are checked against approved drawings during detailing, and clashes are closed before fabrication.
How are fireproofing and coating handled?
Coating systems or fireproofing follow the project specification, with surface preparation grade and coating compatibility confirmed before fabrication.
How is material traceability maintained?
Mill certificates and heat numbers are matched to member marks, and welding and inspection records are issued with each batch.
Are pressure vessels and piping installation included?
No. This page covers steel member fabrication and delivery; pressure vessels, piping installation and process design remain with the other project parties.
Which inputs are needed for a quote?
Drawings or models, member types and quantities, material grade, fireproofing and coating requirements, delivery location and programme.
