We can produce custom sizes that are not specified in the standards with the specified inner diameter, outer diameter, and length using butt welding.
Size: TP340 0.30txφ200x500L (both ends melted) Application: Bellows and similar products Features: We can produce custom sizes not specified in the standards with your specified inner diameter, outer diameter, and length through butt welding. It is characterized by being resistant to cracking of the weld bead even after forming processes like bellows (welding conditions are determined after confirming forming conditions). Order lot: 10 pieces Our welded pipes are made by cutting and roll forming from sheet material and using the micro-plasma welding method. Welding is performed without filler material in a butt joint shape. The weld bead has minimal unevenness and distortion, achieving high precision and receiving positive feedback. Features: - Can be produced in a thickness range of 0.05 mm to 1.0 mm. - Production can be accommodated from just one piece. - Production is possible not only in stainless steel but also in special materials such as titanium, Hastelloy, Inconel, and nickel. - Production and shipping can be done in as little as two days. - All manufacturing is done in-house. We produce prototypes, development products, and custom items according to application and required quantity. For the sizes of welded pipes, please refer to the special page → catalog list → quick reference table for the range of welded pipe manufacturing.

Company information
Nissei Kiko Co., Ltd. has been engaged in precision welding processing, primarily focusing on stainless steel foil materials (ultra-thin materials), for 40 years since the founder encountered 0.05 mm butt welding, with the motto of being a pioneer in precision welding. In addition to stainless steel, we also handle welding of pipes with butt joints of 1.0 mm or less in materials such as titanium, Hastelloy, and Inconel, and we provide contract processing for precision equipment parts, including vacuum devices, semiconductor manufacturing equipment, ultra-low temperature devices, fuel cells, and nuclear-related components, from welding to assembly. From prototype development with a single piece to batch production of several hundred pieces, we offer precision, accuracy, and sincerity with the nimbleness characteristic of a small factory.
