Client Background

The client operates a modern autoclaved aerated concrete (AAC) production facility overseas. To meet surging regional demand for lightweight building blocks, the plant initiated a major capacity expansion.

Key customer requirements:

• Autoclave production in less than 75 days
• Full certification and inspection reports
• Professional sea-shipment packaging
• Fixed delivery schedule aligned with plant construction
• Stable curing performance for large-volume block batches.
• Long service life under repeated daily thermal stress.
• Proven export manufacturing capability with complete pressure vessel certifications.

Project Requirements: Reliable TAIGUO Industrial Autoclaves

AAC blocks demand high-pressure steam curing inside sealed pressure vessels. The chemical reaction creates the structural strength and low density required for modern masonry.

To ensure uninterrupted plant operations, the client specified precise engineering standards:

• Large Internal Vessel Diameter: The Ø2.85m diameter accommodates high-density cake stack trolleys.
• Continuous 36m Curing Length: Extended length maximizes output per single autoclaving cycle.
• Precision Door Safety Interlocks: Dual-safety locks prevent door operation under residual pressure.
• Reliable Global Logistics: Equipment units require customized export protection against marine salt corrosion.

Technical Specifications of the TAIGUO Industrial Autoclaves

TAIGUO built both autoclave vessels to strict heavy pressure vessel standards:

Technical Parameter	Engineering Specification
Equipment Name	Industrial Pressure Autoclave
Core Application	AAC Block & Panel Steam Curing
Internal Diameter	2.85 m
Effective Vessel Length	36 m
Total Units Supplied	2 Units
Vessel Shell Material	Q345R / GB713 Dedicated Pressure Vessel Steel
Working Pressure / Temp	1.6 MPa/ 204℃
Safety Testing Standards	100% Non-Destructive Testing (NDT) + Hydrostatic Test

Manufacturing Quality Control of TAIGUO Industrial Autoclaves

Manufacturing heavy pressure vessels requires absolute precision across every fabrication stage. TAIGUO applied rigorous quality assurance protocols throughout the production phase.

1. Precision Steel Plate Rolling & Shell Assembly

We used heavy-duty plate bending machines to roll high-strength Q345R pressure vessel steel. Alignment control ensures minimal wall variance along the entire 36-meter body.

2. Automated Submerged Arc Welding (SAW)

Automated welding heads created uniform longitudinal and circumferential seams. Multi-pass welding maintains deep penetration and structural elasticity.

3. Non-Destructive Testing (NDT)

Independent inspectors performed $100\%$ Radiographic Testing (RT) and Ultrasonic Testing (UT) on all main pressure welds. This step guarantees zero internal material defects.

4. Hydrostatic Pressure Testing

Before surface finishing, each assembled vessel underwent hydrostatic testing at $1.25$ times the design pressure. The vessel maintained pressure stability without deformation.

TAIGUO’s Manufacturing & Inspection Process

To meet the customer’s urgent timeline, TAIGUO arranged a dedicated production team to accelerate fabrication while maintaining national pressure vessel standards.

Manufacturing Steps Completed

• Steel plate cutting & rolling
• Automatic submerged-arc welding
• Door ring forging & machining
• Internal rail installation
• Pressure vessel nondestructive testing (X-ray, UT, MT)
• Hydrostatic pressure test at 1.65 MPa
• Final exterior treatment & anticorrosive coating

Inspection and Certification Delivered

• Pressure vessel license (D1/D2)
• Hydrostatic test report
• Material certificates (Q345R)
• QC checklist & factory acceptance test report
• Export standard packaging approval
