不銹鋼裝飾管屬於冷拔無縫鋼管還是焊管呢？

不銹鋼裝飾管屬於冷拔鋼管。冷拔無縫鋼管具有中空截面，大量用作輸送流體的管道，鋼管與圓鋼等實心鋼材相比，在抗彎抗扭強度相同時，重量較輕，是一種經濟截面鋼材，廣泛用於制造結構件和機械零件。采用軋制、拉拔、擠壓或穿孔等方法生產的整根鋼管表面沒有接縫的冷拔鋼管。 一種具有中空截面、周邊沒有接縫的圓形，方形，矩形鋼材，用鋼錠或實心管坯經穿孔制成毛管，然後經熱軋、冷軋或冷撥制成。
Stainless steel decorative pipe belongs to welded pipe. Cold-drawn seamless steel pipe has hollow section, which is widely used as pipeline for conveying fluid. Compared with solid steel such as round steel, steel pipe has lighter weight when its bending and torsion strength is the same. It is a kind of economic section steel and widely used in manufacturing structural parts and mechanical parts. The whole steel pipe without seams on its surface is produced by rolling, drawing, extrusion or piercing. A round, square, rectangular steel with a hollow section and no seams around it. It is made of perforated ingots or solid billets and then hot-rolled, cold-rolled or cold-drawn.
冷拔鋼管也稱焊接鋼管，生產工藝簡單，效率高，品種規格多，設備資少，但一般強度低於冷拔無縫鋼管。是用鋼板或帶鋼經過卷曲成型後焊接制成的鋼管。
Welded pipe, also known as welded steel pipe, has simple production process, high efficiency, many varieties and specifications, and less equipment, but its general strength is lower than t彩色沥清地坪hat of cold-drawn seamless steel pipe. It is a steel pipe made by welding steel plate or strip after coiling and forming.
從不銹鋼裝飾管與冷拔鋼管的區別來看，不銹鋼裝飾管應該屬於冷拔鋼管。
