304 decoration stainless steel tube

Decorative pipe is a kind of welded pipe, which is widely used in decoration industry.Steel pipes are usually welded from steel or steel strips after they have been curled and formed by machine sets and dies.With”Simple production process”, “high production efficiency”, “more varieties” and “specifications”, “less equipment cost”.

304 Welded Stainless Steel Tube

304 stainless steel welded pipe is referred to as 304 stainless steel welded pipe. Stainless steel welded pipe is usually made of stainless steel sheet or strip after being curled and formed by machine and die.

304 Stainless steel seamless pipe

304 Stainless steel seamless pipe is a kind of long steel with hollow section and no joint around it.The process of this product determines its limited performance. Generally, the precision of seamless steel tube is low: uneven wall thickness, low brightness inside and outside the tube, high cost of length fixing, and there are pits and black spots on the inside and outside surface which are not easy to remove; its detection and shaping must be off-line processed. Therefore, it embodies its superiority in high pressure, high strength and mechanical structure materials.
