Petrochemical Equipment Installation

Heavy-Duty Manufacturing.

100% of critical Complete Joint Penetration (CJP) welds undergo Ultrasonic Testing (UT per ISO 17640 / ASTM E164) or Magnetic Particle Testing (MT per ISO 17638 / ASTM E709). Radiographic Testing (RT) is applied as requested for heavy sections. Weld acceptance conforms strictly to ISO 11666 Acceptance Level 1 or AWS D1.1 criteria. High-performance protective coatings are applied using airless spray technology in compliance with ISO 12944 (C3 to CX corrosive environments), featuring Inorganic/Organic Zinc-Rich Epoxy Primers, Epoxy Micaceous Iron Oxide Intermediate coats, and Polyurethane/Fluorocarbon Topcoats. Dry Film Thickness (DFT) is verified using calibrated magnetic gauges adhering strictly to the 90/10 rule.

Technical Parameters

To be confirmed

Parameter	What it is set from
Structures	To be confirmed
Design basis	Shijie Heavy Industry’s engineering team is highly proficient in international design codes, including American Standard (AISC 360), European Standard (EN 1993), Australian Standard (AS 4100), and Chinese Standard (GB 50017).
Loads	We rigorously calculate wind, seismic, and snow loads specific to your project’s geographical location to ensure absolute structural safety and regulatory approval.
Corrosion protection	High-performance protective coatings are applied using airless spray technology in compliance with ISO 12944 (C3 to CX corrosive environments), featuring Inorganic/Organic Zinc-Rich Epoxy Primers, Epoxy Micaceous Iron Oxide Intermediate coats, and Polyurethane/Fluorocarbon Topcoats. Dry Film Thickness (DFT) is verified using calibrated magnetic gauges adhering strictly to the 90/10 rule.
Welding and NDT	Welding is performed exclusively by AWS D1.1 or EN ISO 9606 certified welders using qualified Welding Procedure Specifications (WPS) supported by Procedure Qualification Records (PQR) per AWS D1.1 / ISO 15614. Submerged Arc Welding (SAW) and Flux-Cored Arc Welding (FCAW) dominate Complete Joint Penetration (CJP) and fillet welds. 100% of critical Complete Joint Penetration (CJP) welds undergo Ultrasonic Testing (UT per ISO 17640 / ASTM E164) or Magnetic Particle Testing (MT per ISO 17638 / ASTM E709). Radiographic Testing (RT) is applied as requested for heavy sections. Weld acceptance conforms strictly to ISO 11666 Acceptance Level 1 or AWS D1.1 criteria.
Execution class	EN 1090-2 EXC2 (certificate 2787-CPR-01627)
Steel grades	We source directly from top-tier state-owned steel mills, ensuring all raw materials—whether H-beams, steel plates, or high-strength bolts—meet strict international mechanical and chemical properties, covering grades like S355, S460, ASTM A36, and A992. Every piece of steel processed in our facility is backed by Mill Test Reports (MTRs) according to EN 10204 Type 3.1. From heat number stamping to final delivery, we guarantee 100% traceability for your peace of mind.
Lead time	To be confirmed
Documentation	A complete Manufacturing Data Report (MDR)—comprising MTRs, NDT records, coating inspection logs, and Certificates of Conformance—is compiled to support CE Marking (DoP under EN 1090) and AISC final acceptance.

How Your Project Is Built

To be confirmed

PHASE 01 / PRE-CONSTRUCTION

Engineering & Foundation

Utilizing advanced BIM platforms such as Tekla Structures, detailed 3D modeling and shop drawings are executed strictly in compliance with AISC 360 or Eurocode 3 (EN 1993).

PHASE 02 / CONSTRUCTION

Fabrication & Erection

Complex geometries, long-span trusses, and heavy framing undergo 1:1 physical trial assembly or high-precision 3D laser scanning virtual assembly per EN 1090-2 / AISC requirements. Bolt hole alignment is verified (≥ 95% free-pass rate for high-strength bolts), and critical dimensions (span, camber, 3D spatial alignment) are verified within tight tolerance limits (±2.0 mm) to eliminate site fitting risks.
