Welded Pipe Fittings
Material: Carbon Steels and Stainless Steels
Maximum Operating Pressure: L Series: 315 bar;S Series: 630 bar
Parts conform to DIN 2353/DIN EN ISO 8434-1
•  Maximum unique capability of L series: nominal pressure of 315 bar; and maximum capability of S series: that of 630 bar.
•  Sealing Capability – Flexible sealing ring is the main sealing type, to ensure the sealing with no leakage. Even if low-viscosity medium such as water is used, gases will be sealed well.
•  Durability – O rings have excellent flexibility and contractility. There is no necessity to retighten their Fittings even after a long-time operation.
•  Recycling/Remanufacturing Capabilities – Removal or installation can be repeated many a time to welding Fittings, with no wear or damage to internal conical surfaces of the Fittings. Damaged O rings can be easily replaced.
•  Welding Fittings are traditionally used for heavy industries, such as oil press machines, mining, iron and steel plants and the shipbuilding industry.
