20# Custom Precision Steel Tube to Drawing Shipped to South Africa Client

Precision machined small bore steel tubes with tight dimensional tolerances are often hard to source from standard pipe inventory, which is why many South African industrial buyers turn to custom tube fabrication. Haihao Group has finished production and delivery of 20# custom precision steel tube to drawing for a South African customer, manufactured strictly following the client’s technical drawing with strict OD and ID tolerance controls.

Product Specification Table

This 20# custom precision steel tube to drawing has an outer diameter of 26.5 mm and inner diameter of 21.5 mm. The dimensional tolerance is tightly controlled: outer diameter tolerance ±0.05 mm, inner diameter tolerance ±0.1 mm, with fixed finished length at 237 mm. The raw material is 20# carbon steel, widely used for precision mechanical and instrumentation components that require stable mechanical properties and good machinability. Unlike standard off-the-shelf pipes, this tube is cut and finished to fixed length with precision bore and outer circle control to match assembly requirements.

During production, our QC team performs sampling and full dimensional verification on every batch of 20# custom precision steel tube to drawing. We measure OD, ID and finished length one by one to confirm all dimensions stay within the required tolerance band. Surface inspection is also carried out to eliminate scratches, pits and surface defects that may affect subsequent assembly or welding. Every production step follows the client’s pipe drawing rather than general piping standards.

Material test certificates and dimensional inspection records are supplied alongside the shipment of this 20# custom precision steel tube to drawing. The full inspection documentation supports the South African client’s incoming quality check and project record keeping. If needed, we can also provide additional surface finishing, cutting, end machining or non-destructive testing services for custom tube orders.

Haihao Group manufactures custom precision carbon steel tubes according to customer drawings for African industrial and mechanical projects. Our workshop can produce 20# custom precision steel tube to drawing and other grades with strict OD/ID tolerances, fixed cut lengths and custom end machining.
