Welded Carbon Steel Tanks


Custom Carbon Steel Tank Fabrication for Industrial & OEM Projects

Able Tanks is a China-based welded carbon steel tank manufacturer specializing in custom-built tanks for OEMs, contractors, and industrial buyers. We focus on practical fabrication—delivering tanks with stable weld quality, controlled dimensions, and reliable performance for real-world applications.

Carbon steel remains one of the most widely used materials for storage and process tanks due to its strength, cost efficiency, and versatility. When combined with proper welding and surface protection, it offers long service life across a wide range of industries.

From initial drawing review to batch production, our team supports your project with clear communication, consistent manufacturing processes, and export-ready delivery.


What We Manufacture: Custom Carbon Steel Tanks

We manufacture welded carbon steel tanks based on your drawings, specifications, or project requirements. Each tank is fabricated with attention to structural integrity, weld strength, and coating performance.

Typical Tank Types

  • Industrial water storage tanks
  • Fuel and diesel storage tanks
  • Oil tanks and lubrication systems
  • Fire protection water tanks
  • Chemical tanks (with suitable coatings/linings)
  • Process tanks and OEM integrated tanks

Size & Configuration

  • Small tanks (100–1,000 liters)
  • Medium tanks (1–20 m³)
  • Large welded tanks (20–200 m³+)
  • Vertical or horizontal tanks
  • Cylindrical, rectangular, or custom designs

We also manufacture tanks integrated with frames, skids, or structural bases for equipment systems.


Carbon Steel Materials & Grades

Material selection affects tank strength, weldability, and corrosion resistance. We follow your specifications or recommend suitable grades based on application and environment.

Common Carbon Steel Grades

  • Q235 / S235 – Standard structural steel for general-purpose tanks
  • Q355 / S355 – Higher strength steel for larger or load-bearing tanks

Plate Thickness Range

  • Typically 2 mm to 20 mm+ depending on tank size and application

Surface Protection Options

Carbon steel tanks require proper surface treatment to ensure durability:

  • Shot blasting (Sa2.5 surface preparation)
  • Powder coating (70–120 μm typical)
  • Industrial painting systems (epoxy / polyurethane)
  • Internal coatings or linings for water or chemical use

Proper surface preparation and coating selection are critical to long-term corrosion resistance.


Welding Processes for Carbon Steel Tanks

Welding is the core of tank fabrication. Our process focuses on strength, consistency, and repeatability.

MIG (GMAW) Welding – Primary Process

MIG welding is widely used for carbon steel tank fabrication:

  • High efficiency for medium and large tanks
  • Stable weld penetration and fusion
  • Suitable for structural welds and long seams
  • Consistent results in batch production

TIG (GTAW) Welding – For Precision Areas

TIG welding is used where higher control is required:

  • Thin materials or detailed sections
  • Root passes or critical joints
  • Cleaner weld appearance

Automated / Robotic Welding

For repeat OEM projects, we apply automated welding processes:

  • Consistent weld quality across batches
  • Reduced variation and rework
  • Improved production efficiency

Fabrication Capabilities: From Plate to Finished Tank

Able Tanks provides integrated fabrication support beyond welding, helping reduce coordination risks and improve overall quality.

Cutting & Forming

  • Fiber laser cutting for steel plates
  • Plasma cutting for thicker materials
  • Plate rolling for cylindrical shells
  • Bending and forming for structural parts

Fit-Up & Assembly

  • Controlled fit-up to minimize distortion
  • Use of jigs and fixtures for repeatability
  • Sub-assembly and full tank assembly

Leak Testing & Inspection

  • Visual weld inspection
  • Dimensional checks
  • Leak testing (air pressure / water testing)

Our goal is to ensure each tank meets both structural and functional requirements before shipment.


Quality Control for Carbon Steel Tanks

We apply a practical quality control system aligned with common international expectations for welded structures.

Key Quality Focus

  • Weld penetration and fusion quality
  • Weld appearance and defect control
  • Dimensional accuracy and tolerance control
  • Coating thickness and surface finish

Standards & References (When Required)

  • Welding aligned with AWS D1.1 (structural welding)
  • ISO 5817 (weld quality levels, typically Class C or B if required)
  • ISO 13920 (welded structure tolerances)
  • Coating systems aligned with ISO 12944

Documentation

  • Drawing confirmation before production
  • In-process inspection records
  • Final inspection reports
  • Basic QA documents available upon request
