This is an explanation of the welded pipe fittings PT370 and PG370.

There are such differences between the PT370 and PG370 pipe fittings.

Among the welded pipe fittings manufactured by Benkan Kiko, the ones with material codes "PG370" and "PT370" are particularly produced in large quantities. We receive many inquiries from customers regarding the differences between "PG370" and "PT370." Pipe fitting "PG370" ... is a pipe fitting for pressure piping. - It connects to the steel pipe STPG370 according to JIS G 3454. - It is mainly used for pressure piping at temperatures below approximately 350°C (excluding high-temperature applications). - The maximum operating pressure is typically below 10MPa. Pipe fitting "PT370" ... is a pipe fitting for high-temperature piping. - It connects to the steel pipe STPT370 according to JIS G 3456. - It is mainly used for high-temperature piping at temperatures exceeding 350°C (up to approximately 450°C). - The maximum operating pressure is typically below 20MPa. These are the differences.

Duplex stainless steel welded pipe fittings

Duplex stainless steel welded pipe fittings

At Benkan Kiko, we manufacture welded pipe fittings made of duplex stainless steel.

The material commonly referred to as duplex stainless steel is characterized by its high resistance to corrosion, as well as its greater strength compared to austenitic stainless steel. This allows for thinner design plate thicknesses, leading to advantages such as weight reduction, downsizing due to increased flow rates, and cost reduction in piping. At Benkan Kiko, we utilize our long-established metal forming technology and quality assurance system to provide high-quality duplex stainless steel welded pipe fittings, assisting our customers with their piping design and cost reduction. Please feel free to contact us with any questions or inquiries. Project Sales Department, Eastern Japan Sales Division TEL: (03) 3777-1521 / FAX: (03) 3777-1567 Project Sales Department, Western Japan Sales Division TEL: (06) 6482-1581 / FAX: (06) 6482-1824

JIS B 2309 Stainless Steel Butt-Weld Pipe Fittings for General Piping

JIS B 2309 Stainless Steel Butt-Weld Pipe Fittings for General Piping

Su pipe fittings (JIS B 2309 general piping stainless steel butt-weld pipe fittings) can be delivered in a short lead time due to inventory availability.

Su joints (JIS B 2309) are manufactured primarily for use in general water supply and hot water piping in hotels, apartments, hospitals, building construction, and factory piping. They are characterized by being thinner than butt-welded pipe fittings produced according to JIS B 2311 and JIS B 2312, which allows for cost reduction. Additionally, considering automatic welding at the construction site, the bevel is designed as a plain end. The maximum allowable pressure is set at 2.0 MPa, and due to the thin wall thickness, even small diameter fittings feature a wide inner diameter, ensuring sufficient flow capacity. Benkan Kiko holds JIS B 2309 Su joints in stock, allowing for relatively short delivery times. <Stock Range> Types: 90EL, 45EL, 90ES, R(C), R(E), T(S), T(R), LJSE Sizes: 30Su to 300Su

Proposal for Prefabricated Piping for Nuclear Power.

Proposal for Prefabricated Piping for Nuclear Power.

Benkan Kiko provides piping materials that meet the requirements of nuclear power management.

Benkan Kiko has a wealth of delivery experience in welded pipe fittings for all nuclear power plants in Japan. Utilizing our expertise in strict quality control for nuclear applications, management of documentation and quality records, and techniques for long and circumferential welding of items subject to inspection by welding contractors, we manufacture not only items subject to welding contractor inspection but also prefabricated piping where nuclear management is required. We have a significant track record in construction measures necessary for the recent restart of nuclear power plants. In particular, we manufacture and deliver prefabricated piping that combines fittings, flanges, nozzles, and nipples for fire protection piping, which traditionally does not require nuclear management. We also conduct strength calculations for these flanges, nozzles, and nipples based on JSME (Japan Society of Mechanical Engineers) standards. We can manufacture using both stainless steel and carbon steel (galvanized), and we are ready to meet various other requests.

Welded pipe fittings made from clad steel

Welded pipe fittings made from clad steel

Clad steel generates benefits in various cases, such as reducing overall piping costs and accommodating materials that can only be purchased in rare materials or thin sheets.

Clad steel is a composite material that uses carbon steel, high-strength steel, low-alloy steel, etc., as the base material, and combines it with a different type of steel on one side through processes such as hot rolling (bonding), welding, or explosive bonding. It allows for the joining of dissimilar metals, enabling the creation of functions that cannot be achieved with a single metal. By combining materials with good corrosion resistance or by using less expensive metals in larger quantities alongside more expensive ones, it is also possible to reduce the overall cost of piping. This type of steel provides advantages in various cases, such as accommodating rare materials or materials that can only be purchased in thin sheets. *The photo shows a cross-section of clad steel, where the combination of dissimilar metals can be seen.
