Wuxi Fanze Special Steel Co., Ltd. is a well-known Wuxi seamless steel pipe plant in Jiangsu, Shanghai and Zhejiang. Wuxi Fanze has gradually expanded its scale since 2005. The company now has more than ten production lines, which can produce seamless steel pipes and seamless square pipes with an outer diameter of Ф6-820mm and a wall thickness of 0.5mm-60mm. In 2008, it added 3 precision steel pipe production lines. , Can produce precision seamless steel pipes with an outer diameter of less than 219mm, small tolerance can be controlled within 0.05mm, roughness can reach 0.2-0.5, product diversification and high-end is the company's strengths. The company has now set up 8 offices in Jiangsu, Zhejiang, Henan, Jiangxi, and Hunan. The company implements a business model of allowing for retail sales, a minimum order, and small profits but quick turnover to occupy a large share of sales in the surrounding market. The company's main products are: Wuxi galvanized square pipe, Wuxi galvanized Q345B seamless steel pipe, galvanized ordinary carbon seamless steel pipe, alloy seamless steel pipe, high and low pressure pipeline pipe, galvanized seamless square pipe, Wuxi precision steel pipe, Small-caliber precision steel pipes, galvanized special-shaped pipes, etc.

    Causes and Control of Q345B Seamless Tube Wrinkling

    Q345B seamless pipe wrinkling causes and controlling wrinkling in stamping production will cause scrapped parts, which not only increases manufacturing costs, but also causes raw material waste, which needs to be analyzed and controlled. The reasons are as follows: 1. The blank holding force of the Q345B seamless pipe is not enough, and the gap between the pressing surface is not suitable for the problem of "inside loose and outside tight". 2.Lubricant is too

    Welding process and requirements of high frequency straight seam steel pipe

    The welding process of high-frequency welding of straight seam steel pipes is performed under the condition of fast heating speed and high cooling speed. Rapid temperature changes cause certain welding stress, and the structure of the weld seam also changes. The structure is low-carbon martensite and a small area of free ferrite; the transition region is composed of ferrite and granular pearlite; and the parent structure is ferrite
