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 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) manufactured 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 and SUS316L, with a manufacturing range from 1.5B to 12B. We can handle both small and large lots, and we 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 your specifications, whether they are unique pieces or mass-produced items. 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.

Alternatively, manufactured by arc welding from steel plates or similar materials. (The flange part may also be manufactured by complete penetration circumferential welding or fillet welding.) However, for diameters of 40A (1-1/2B) or less, it may be manufactured by cutting from steel bars. *Quoted from JPF SP 001 manufacturing methods.
