Haihao Group recently completed the delivery of custom-manufactured steel pipe products for a customer in South Africa.
The order was produced strictly according to the client’s technical drawing, ensuring accurate dimensions, consistent quality, and full compliance with project-specific requirements.
This project reflects Haihao Group’s strong capability in non-standard steel pipe fabrication, particularly for applications where standard specifications cannot meet design or assembly needs.
Custom carbon steel pipe manufactured by Haihao Group according to client drawing for South Africa project
Product Details
The supplied product is a precision-cut carbon steel pipe, customized in size and length based on drawing confirmation.
Key specifications include:
- Product type: Custom steel pipe (manufactured to drawing)
- Outer diameter (OD): 32.95 mm
- Inner diameter (ID): 26.95 mm
- Length: 42 mm
- Material: 20# carbon steel
- Manufacturing standard: According to customer drawing
All dimensions were tightly controlled during production to ensure proper fit during on-site installation.
Custom Manufacturing Based on Technical Drawings
Unlike standard pipes produced to ASTM or EN norms, this project required drawing-based manufacturing, with special attention to:
- OD and ID tolerance control
- Accurate cutting length
- Smooth inner and outer surface finish
- Material consistency for machining or assembly
Haihao Group’s production team closely reviewed the drawing before manufacturing, ensuring that every detail was fully understood and executed.
Material: 20# Carbon Steel
The pipe was produced using 20# carbon steel, a widely used material known for:
- Good mechanical properties
- Excellent machinability
- Stable performance in general industrial applications
- Cost-effective solution for custom components
This material is commonly applied in mechanical parts, equipment structures, and industrial assemblies.
Quality Control and Inspection
To guarantee product reliability, Haihao Group applied strict quality control measures, including:
- Raw material inspection
- Dimensional measurement of OD, ID, and length
- Visual inspection of surface quality
- Final inspection before packing and shipment
Each step was documented to ensure traceability and consistency.
Applications
These custom steel pipe components are suitable for use in:
- Industrial equipment assemblies
- Mechanical structures
- Engineering components
- Customized pipeline or support systems
