Product Description
Also called solenoid tube or solenoid. Spiral pipe diameter, about 30 HaoWeiMi diameter is about 10 HaoWeiMi, adjacent to HaoWeiMi spiral distance approximately 11. Spiral pipe every week by six small body and a H1 histone located within the lumen spiral surface, the structure of the spiral pipe to maintain plays an important role. From small body composition of 10 HaoWeiMi fiber spiral formation HaoWeiMi 30, crude fiber length compression 6 times further DNA.
Characteristics: spiral pipe welded pipe production process is simple, high production efficiency, low cost, rapid development. Spiral welded pipe strength welded pipe is general tall, narrow the blank with larger diameter of welded pipe production, still can use the same width of billet production of different welded pipe diameter. But with the same length of pipe welding seam, until 30 ~ 100%, the length of increasing production and low speed. Therefore, a small-bore tube welding the weld seam, mostly adopts straight heavy-calibre welded pipe is mostly using spiral welded.
