Description:
304 stainless steel welded steel pipe or 304 stainless steel welded pipe.Commonly used stainless steel plate or steel strip after crimp units and dies made of stainless steel welded pipe welding.304 stainless steel welded pipe production process is simple,efficient production,more specifications,the investment for equipment is less.But the general strength is lower than stainless steel seamless steel tube.
In recent years,with the rapid development of high quality stainless steel strip steel rolling production and stainless steel welding and inspection technology.Weld quality enhances unceasingly.The variety of welded stainless steel pipe specifications are increasing.And especially in the heat transfer in more and more fields who spare pipe, decorative, low pressure fluid in the tube instead of stainless steel seamless steel tube.
Small 304 stainless steel welded pipe is the continuous online production.Wall thickness is thicker, the unit and dissolves equipment investment.The less it has economical and practical.The thinner wall thickness, its input-output ratio will be reduced.
