GNEE STEEL Ships Custom SA 516 Gr70 Transition Pieces to Kazakhstan

2026-07-17 | More News

GNEE STEEL, a leading integrated steel supplier and precision fabricator, announced the successful completion and shipment of custom steel transition pieces for a thermal incineration project in Pavlodar, Kazakhstan. This order underscores the company’s one-stop fabrication capability for pressure vessel and environmental equipment components, from raw material supply to finished part delivery.

Project & Product Overview

The shipment includes 2 sets of steel transition pieces designed for plate welding assemblies in a thermal incineration manifold system. The components are manufactured from SA 516 Grade 70 (S5) pressure vessel steel in full compliance with ASME standards, featuring a conical reducer geometry with end diameters of 660.4 mm and 508 mm and a uniform wall thickness of 15 mm.

Production was executed strictly according to customer-supplied fabrication drawings and technical annexes. Key mandatory requirements included:

Precision cold forming of the curved conical profile per flat-pattern layout drawings
Full-penetration longitudinal and transition welds
100% non-destructive testing (NDT) via ultrasonic or radiographic methods on all weld seams
Full material traceability with official Material Test Certificates (MTC)

Fabrication Process & Quality Assurance

Leveraging its 35,000 m² modern processing base and certified technical team, GNEE STEEL completed the full production cycle in-house:

Precision blanking: CNC cutting of SA 516 Gr70 steel plates is performed based on the development drawing to ensure the accuracy of the developed dimensions.
Edge preparation: Machining of standard weld bevels for full joint penetration
Roll forming: Three-roller plate bending to form the conical shape with controlled roundness and dimensional tolerance
Automatic welding: Full-penetration longitudinal seam welding by certified welders
NDT inspection: 100% UT/RT examination of all welds performed by qualified inspectors, with formal inspection reports issued
Final verification: Dimensional check, surface treatment and documentation review prior to packaging

“Components for thermal and pressure equipment leave no room for error in either material or workmanship,” said a project spokesperson at GNEE STEEL. “By combining our ready stock of ASME-spec pressure vessel plates with in-house forming, welding and testing capabilities, we delivered finished, inspection-ready parts in a shortened lead time, helping our customer keep their project on schedule without the hassle of coordinating multiple suppliers.”

Full-Range Steel Plate Processing Services from GNEE STEEL

Beyond custom pressure vessel components, GNEE STEEL provides end-to-end plate processing solutions serving shipbuilding, heavy machinery, power, mining, offshore engineering and other industries:

1. Precision Cutting Services

Equipped with imported laser, plasma, flame, waterjet and saw cutting equipment, the company supports blanking of complex shapes from 2D/3D drawings. Cutting capacity covers thicknesses from 0.5 mm up to 150 mm with tolerances as tight as ±0.05 mm, suitable for carbon steel, alloy steel, stainless steel and other materials.

2. Forming & Roll Bending

CNC press braking: Bends plates into angles, channels and custom structural profiles
Plate rolling: Forms cylinders, cones and curved structures for pressure vessels, pipelines and tanks
Straightening & leveling: Eliminates internal stress and ensures plate flatness for downstream processing

3. Machining & Edge Preparation

CNC gantry milling, boring, drilling and turning for large and heavy steel components
Standard V/X/K-type bevels and custom edge preparation to meet welding requirements for shipbuilding and pressure vessel fabrication

4. Welding & Structural Fabrication

Certified manual and automatic welding services per international codes, with full NDT inspection (UT, RT, MT, PT) and third-party verification by SGS, BV and TÜV available upon request.

5. Surface Treatment & Protection

Deburring, grinding and polishing for smooth surface finish
Shop primer, epoxy coating and anti-corrosion painting
Hot-dip galvanizing for long-term outdoor and marine corrosion resistance

All processing services are delivered under ISO 9001 and ISO 14001 management systems. GNEE STEEL accepts both small-batch custom fabrication and large-volume project orders, with tailored packaging and global logistics support for container and bulk cargo shipments worldwide.
