　　Recently, many customers often receive information about the price of spiral steel pipe. They ask directly, but they do not know that the parameters of spiral steel pipe directly determine the price of spiral steel pipe.

　　Firstly, the specifications and models determine the price.

　　The external diameter and wall thickness specifications of spiral steel pipe directly determine the price of steel pipe. After all, the basic price of each specification of spiral steel pipe is different.

　　Secondly, the implementation criteria determine the price.

　　At present, the main implementation standards of Premier API 5L 20Inch Welded Spiral Steel Pipe are Ministry Standard, National Standard and American Standard. But for a while, the spiral steel pipe manufactured by manufacturers can not even meet these standards. The prices of each standard are different, basically the difference is about 400 yuan/ton.

　　Third: Material determines price

　　At present, the most common material on the market is Q235B, which is the cheapest one. Other materials are Q345B, L290, L360 and so on. The higher the grade of material, the higher the natural price.

　　Fourth: The type of anticorrosion on the outer wall determines the price.

　　There are many kinds of anti-corrosion for spiral steel pipe. At present, the highest price is 3PE anti-corrosion. Others are epoxy coal tar pitch anti-corrosion, plastic coating anti-corrosion, IPN8710 anti-corrosion, and even several kinds of anti-corrosion should be carried out simultaneously.

　　Therefore, the price of spiral steel pipe is determined by many factors at the same time. When purchasing, we must know exactly what type of steel pipe we want to buy.
