Compatible with JPF, JIS, JPI, and ASME standards! Materials other than SUS304 are also available!
At Benkan Kiko, we manufacture a wide range of welded pipe fittings, from custom orders to mass production of standard products, including both domestic and overseas factories, to meet our customers' diverse needs. This time, we would like to introduce our stainless steel stub ends (also known as lap joints) produced at our Osaka factory. Regarding standards, we have molds that cover JPF, JIS, JPI, MSS, and ASME, and we can accommodate stainless steel types other than the commonly used SUS304 or SUS316L, with a manufacturing range from 1.5B to 12B. We can handle small to large lots and also offer short delivery times. Additionally, since we manage everything in-house from material cutting to shaping, heat treatment, and inspection, we have absolute confidence in our quality control. We can provide items tailored to customer specifications, from unique one-off pieces to mass production. Because we manufacture in our own factory, we can also accommodate requests such as "considering products with slightly different dimensions than the standard" or "if there were such stub ends..." So please feel free to consult with us.

The standards primarily used in Japan are as follows: JPF (Japan Metal Joint Association) Standard: JPF SP 001 (5K/10K/16K/20K) JIS (Japanese Industrial Standards) Standard: JIS B 2309 (SU Joint) JPI (Japan Petroleum Institute) Standard: JPI-7S-15 MSS (Manufacturers Standardization Society of the Valve and Fittings Industry) Standard: MSS SP-43 ASME (American Society of Mechanical Engineers) Standard: ASME B16.9 Manufactured by hot or cold plastic processing from steel pipes. Alternatively, manufactured from steel plates by arc welding of longitudinal seams. (The flange part may also be produced by complete penetration circumferential welding or fillet welding.) However, for sizes with a nominal diameter of 40A (1-1/2B) or less, it may be manufactured by cutting from steel bars. *Quoted from JPF SP 001 Manufacturing Method.
