The main use of spiral welded pipe is different from that of straight welded pipe. The main use of spiral welded pipe is widely used in civil engineering construction such as houses, bridges and roads. Major Origins: Spiral pipe manufacturers are mainly distributed in North China and Northeast China. North China, such as Shougang, Tanggang, Xuangang, Chenggang, and Northeast China, such as Xilin, Beitai and Fugang, account for more than 50% of the total output of screw steel. Spiral welded pipe is widely used in natural gas, petroleum, chemical industry, electric power, thermal power, water supply and drainage, steam heating, penstock for hydropower station, thermal power, water and other long-distance transmission pipelines and piling, dredging, bridge, steel structure and other engineering fields. The quality of spiral welded pipe is thin and low, and the phenomenon of filling is often unsatisfactory. The reason is that in order to achieve a large negative tolerance, the manufacturer has a large reduction in the first several passes of the finished product, a small iron shape and a unsatisfactory filling of the pass. 伴隨相關過程推（tuī）進（jìn）百姓經濟領域的持續發展（zhǎn）和普通人積極性整體水平的使原有水（shuǐ）平上升（shēng）,螺旋形焊管目前已經轉變為中（zhōng）國大陸（lù）給彈道係統持續發展的新發（fā）展趨勢.公司連貫性進行崇拜"質量老大，客（kè）戶至高無上，以誠會友，高科技（jì）興企"。河北古代（dài）無（wú）縫鋼管製造（zào）著名（míng）公司的邏輯學是"進行合作、提出並（bìng）采（cǎi）用新的方法、發展、持續發展"。 我本自公司創辦以來，始終重視對產品的質量（liàng）及對困難度產品的進行加工進行管理（lǐ）、與此同時對外繼續多種困難度進行（háng）加工生產焊管業務範（fàn）圍。達成使用者最容（róng）易的實（shí）際價值，是我們（men）的比賽主要目標。
With the development of national economy and the improvement of people's living standards, spiral welded pipe has become a new trend in the development of domestic pipeline system. The company has always believed in "quality first, customer first, sincere friends, science and technology to thrive enterprises". The philosophy of Hebei Tianyuan Steel Tube Manufacturing Co., Ltd. is "cooperation, innovation, progress and development". Since the founding of our company, we have been focusing on the quality of products and processing management of high-difficulty products, while undertaking a variety of high-difficulty processing and production of welded pipe business. It is our goal to realize the most perfect value of users.
螺（luó）旋形焊管與直縫焊（hàn）管的差異
Difference between Spiral Welded Pipe and Longitudinal Welded Pipe
直縫埋弧焊管是用謄（téng）寫鋼版生產的，而螺旋形焊管是用熱（rè）軋卷板生產的。熱（rè）軋帶鋼醫衛組研製生產工藝具備一多個係列的長處，具（jù）備取得生產質量更好線坯（pī）子鋼的冶（yě）金（jīn）學生產工（gōng）藝實際（jì）能力。比如，在說道（dào）台架演出有（yǒu）水比賽（sài）係統以加快比賽（sài），這就決定采用（yòng）低（dī）鋁合金本人成分來實現較為額外的極限抗拉強（qiáng）度等級提升和超低溫柔韌，進而進行改造鋼鐵的可焊性。但這一係統在謄寫鋼版生產廠大體上並未。卷（juàn）板的鋁合金容量(碳化（huà）學當量)經常不可企及好像等級提升的（de）謄寫鋼版，這也增強了螺旋形焊管的可焊性。
Longitudinal submerged arc welded pipe is made of steel plate, while spiral welded pipe is made of hot rolled coil plate. The rolling process of hot-rolled strip mill has a series of advantages. It has the metallurgical ability to produce high quality pipeline steel. For example, a water cooling system is installed on the output bench to accelerate cooling, which allows the use of low alloy components to achieve special strength grades and low temperature toughness, thereby improving the weldability of steel. But this system is basically not available in steel plate factories. The alloy content (carbon equivalent) of coiled sheets is often lower than that of similar grade steel sheets, which also improves the weldability of spiral welded pipes.
更有必要作（zuò）出說明的是，因為螺旋形焊管的卷（juàn）板研製（zhì）大方向並（bìng）非鉛垂線（xiàn）無縫鋼管軸線大方（fāng）向(其夾解參加於無縫鋼（gāng）管的螺旋形角（jiǎo）)，而直（zhí）縫無縫鋼管的（de）謄寫鋼（gāng）版研製大方向鉛垂線於無縫鋼管軸線大方向，所以，螺旋形焊管材料的抗裂使用性能優惠直縫無縫鋼管。
More importantly, because the rolling direction of spiral welded pipe coil is not perpendicular to the axis of the steel pipe (its clamping depends on the spiral angle of the steel pipe), while the rolling direction of the steel plate of the straight welded pipe is perpendicular to the axis of the steel pipe, the crack resistance of the spiral welded pipe material is better than that of the straight welded pipe.
