TOKYO--(BUSINESS WIRE)--NIPPON KINZOKU CO., LTD. (Headquarters: Minato-ku, Tokyo) has commercialized “FINE PIPE” *1, a welded drawn pipe that surpasses “seamless pipe” by using carefully selected materials and unique processing technologies (welding, drawing, annealing) only available from a raw material manufacturer.
These products meet the needs for higher precision in small-diameter pipe manufacturing, and we have received many inquiries and orders for the “FINE PIPE” series are expanding.
|
Features of "FINE PIPE" *1 |
|
| 1. |
Higher precision than seamless pipes, and continuous processing of coil products improves productivity and enables significant cost reductions |
| 2. |
Minimal thickness deviation, unique welding technology, and full length control of the welded part provide pressure resistance and durability that surpasses seamless pipes. |
| 3. |
Complete quality assurance system using in-line inspection equipment from materials to final products |
| 4. |
Selectable product supply options, such as coil-wound, fixed-length, cut-to-length, and specially processed products |
|
Notes: Refer to *1 for manufacturing range and steel grades handled. |
|
|
Features of “High-precision internal surface” small diameter pipe *2 |
|
| 1. |
Significantly improved inner surface roughness compared to conventional products |
| 2. |
The internal surface is perfectly round and well-formed, with stable quality in the longitudinal direction. |
| 3. |
No post-processing is required, resulting in significantly reduced costs compared to polished finishes. |
|
Notes: Refer to *2 for manufacturing range and steel grades handled. |
|
|
Features of "FINE PEEK-ST" *3 |
|
| 1. |
High-precision, high-strength column tube with PEEK resin pipe protected by stainless steel |
| 2. |
Can be used in ultra-high pressure environments of 100Mpa or more |
| 3. |
Dramatic improvement in roundness and internal surface roughness even with a small inner diameter (Internal surface roughness Ra 0.3 μm or less) |
| 4. |
The coil shape of up to 20M can be cut to any length, contributing to reduce costs and improve yields. |
|
Notes: Refer to *3 for manufacturing range and steel grades handled. |
