                                                                                                                                    熱軋直縫鋼管中的熱軋是相對于冷軋而言的,冷軋是在再結晶溫度以下進行的軋制,而熱軋就是在再結晶溫度以上進行的軋制。熱軋直縫鋼管采用的是德國技術的制造設備及先進的渦流探傷設備。
                                                                                                                                    熱軋直縫鋼管的材質: 本產品材質為10#,20#,35#,45#,X42, X60, X80, Q235,Q295,Q345,也可根據客戶需求自選材質。
                                                                                                                                    熱軋直縫鋼管分一般鋼管,低、中壓鍋爐鋼管,高壓鍋爐鋼管、合金鋼管、不銹鋼管、石油裂化管、地質鋼管和其它鋼管等。
                                                                                                                                    熱軋直縫鋼管在日常中有很多的用途,有些可以當做其優點,有些相比來說則成了其缺點。讓我們來具體的看下其用途,以及其優缺點之分。
                                                                                                                                    熱軋 適應于一般結構、機械結構件 天津無縫鋼管廠、衡管、冶鋼、鞍鋼、上一、合鋼、通鋼、本鋼、西寧鋼廠、長特、成無、安鋼、包鋼。
                                                                                                                                    熱軋低中壓鍋爐管 熱軋 制造各種結構低中壓鍋爐過熱蒸汽管、沸水管及機車鍋爐用過熱蒸汽管、大煙管、小煙管和拱磚管 衡管、冶鋼、上一、鞍鋼、通鋼、西寧鋼廠、成無、天津無縫、包鋼。
                                                                                                                                    熱軋直縫鋼管優點:可以破壞鋼錠的鑄造組織,細化鋼材的晶粒,并消除顯微組織的缺陷,從而使鋼材組織密實,力學性能得到改善。
                                                                                                                                    其缺點:經過熱軋之后,鋼材內部的非金屬夾雜物(主要是硫化物和氧化物,還有硅酸鹽)被壓成薄片,出現分層(夾層)現象。熱軋的鋼材產品,對于厚度和邊寬這方面不好控制。
                                                                                                                                    熱軋直縫鋼管適用范圍: 本產品廣泛應用于中低壓流體輸送管道,煤氣管道、天然氣管道、供水管道、污水處理管道、空調管道、消防管道、建筑工程、化工工程、石油管道工程、供熱取暖工程及設備工程等是近兩年開發的國家“九五”重點高新技術推廣項目和國家“火炬”計劃項目,適用于石油天然氣工業。給排水工程、化學工業、電力工業農業灌溉、城市建設,也可用于氣體輸送管道用,并可做結構管使用,打樁、橋梁、碼頭、道路等通用。
