Development of Manufacturing Process Technologies of Stainless Steel Weld Pipes for Making of Low/Medium Pressure

摘要: 不銹鋼焊接鋼管在中低壓鍋爐及熱交換器上替代無縫鋼管已勢在必行,特別是自動焊接鋼管經(jīng)冷加工處理后,其性能已達(dá)到無縫鋼管的指標(biāo)。研究開發(fā)了鍋爐、熱交換器用不銹鋼焊接鋼管的生產(chǎn)工藝,并重點(diǎn)對成型、自動焊接、熱處理、冷加工四個(gè)工藝難關(guān)進(jìn)行了技術(shù)攻關(guān)。簡介了該產(chǎn)品的主要生產(chǎn)工藝特點(diǎn)。

Abstract: It is inevitable for stainless steel weld pipes to take the role of seamless steel pipes in the area of making of low/medium pressure boilers and heat exchangers, particularly for cold processed automatically welded pipes which are in possession of properties in compliance with the technological indicators set for seamless steel pipes. Manufacturing process of stainless steel weld pipes for boiler and heat exchanger purpose has been developed, focusing on four crucial process aspects, namely, forming, auto-welding, heat treatment and cold-processing. Described here are the main characteristics of manufacturing process of the said product.
