Spiral piling pipe technical characteristics and applications. Spiral welded steel pipe with reliability and adaptability varieties, spiral steel pipe plant in recent years, the proportion of the number stabilized at 42% to 45% or so. Especially adapted to the production of thick-walled steel and alloy steel.
Spiral steel pipe is mainly used for reinforced concrete building elements of the skeleton. Usually with two longitudinal ribs uniformly distributed along the length of the transverse ribs. Rebar is a small section steel, spiral steel pipe with plain bars is the difference between appearance with longitudinal ribs and transverse ribs. Requires the use of a certain degree of mechanical strength, bending properties and process welding performance. Billets as feedstock production spiral disposition by sedation melting carbon steel or low alloy steel, hot-rolled steel scrap forming, normalizing or rolled condition.
Spiral piling pipe technical features include: high investment, high interest rates, complex manufacturing process, a large wall thickness and ovality tolerance. The fact sheet welded tube deep processing products, prices of similar conditions, the spiral steel pipe market competitiveness and increase its reliability, as from time to time to improve the quality of steel and welded raise the level of technical equipment, the local spiral pipe occupy market, there is the possibility of substitution welded pipe, but only a very limited field.
