螺旋鋼管是一種用于輸送生活和工業廢水或污水的污水管。特別是近年來，隨著新技術、新材料的發展，許多具有不同特點和優勢的新型管道被開發出來，并以良好的性能應用于排水行業。
Spiral steel pipe is a kind of sewage pipe used for conveying domestic and industrial waste water or sewage. Especially in recent years, with the development of new technology and new materials, many new pipes with different characteristics and advantages have been developed and applied to drainage industry with good performance.

濟南螺旋管廠家直銷排水管道工程中使用的主要金屬管道有鋼管、球墨鑄鐵管、灰口鑄鐵管。
The main metal pipes used in drainage engineering are steel pipes, ductile iron pipes and grey cast iron pipes.

鋼管機械強度高，耐壓性好，制造使用方便，適用于復雜地形，但管子的防腐和保護存在問題。與其他金屬管道一樣，鋼也容易腐蝕，因此在水管中使用時，應內襯瀝青涂層，以防止酸性水的侵蝕。這也保留了其良好的流動特性。各種涂層和襯里的缺點是在安裝過程中可能會損壞涂層的使用壽命直接受到鋼管表面處理質量和聚乙烯組合的影響，因此鋼管的成本非常高。
The steel pipe has the advantages of high mechanical strength, good pressure resistance, convenient manufacture and use, and is suitable for complex terrain. Like other metal pipes, steel is prone to corrosion, so when used in pipes, they should be lined with an asphalt coating to prevent the erosion of acidic water. This also preserves its good flow characteristics. The disadvantage of various coatings and linings is that they can damage the service life of the coating during installation and are directly affected by the quality of the surface treatment of the steel pipe and the polyethylene combination, so the cost of the steel pipe is very high.

濟南螺旋管廠家直銷鋼材的主要優點是強力。通常不會出現裂紋，在異常載荷下，材料彎曲而不是斷裂大直徑鋼管是污水和廢水處理更常用的壓力管道?？梢允褂萌N方法：無縫、焊接和鑄造模具。
The main advantage of steel is its strength. Cracks usually do not occur, and large diameter steel pipes are the most commonly used pressure piping for sewage and wastewater treatment under abnormal loads. Three methods can be used: seamless, welded, and cast molds.
