It takes the steel strip of specifications as the raw material and produces the round pipe and square rectangular pipe of required specifications through the cold-formed forming and high-frequency welding methods. The unit in the digestion and absorption of similar equipment at home and abroad on the basis of bold innovation, and widely listen to the user's opinion, design and manufacturing, equipment operation is economical and reliable, good stability. It is suitable for low carbon steel and low alloy steel, the material must be σb≤520MPa, σs≤345MPa. The process flow of HG32 welded pipe production line is: feeding and unwinding → straight head → clamping and leveling → cutting and butt welding → lofting material storage → forming → welding → removing outer burr → cooling → sizing → fixed size flying saw (cutting) → roller table → blanking (packing) → finished products warehousing What is the production process of HG32 welded pipe unit? Straight welded pipe production process is simple, high production efficiency, low cost, rapid development. The strength of spiral welded pipe is generally higher than that of straight welded pipe, and the welded pipe with larger diameter can be produced with narrower billet, and the welded pipe with different diameter can also be produced with the same width billet. But compared with the same length of straight seam pipe, the weld length is increased by 30~100%, and the production speed is lower. Therefore, the welded pipe of small caliber mostly adopts straight seam welding, and the welded pipe of large caliber mostly adopts spiral welding. 1. Welded steel pipe for low pressure fluid transportation (GB/T3092-1993), also known as the general welded pipe, commonly known as black pipe. It is a welded steel pipe used for conveying water, gas, air, oil and heating steam and other general low pressure fluids and other purposes. The wall thickness of steel pipe is divided into ordinary steel pipe and thickened steel pipe. The pipe end is divided into two forms: steel pipe without screw (light pipe) and steel pipe with screw. The specification of the steel pipe is indicated by the nominal diameter (mm), which is the approximate value of the inner diameter. Traditionally, welded steel pipes used for low-pressure fluid transportation are used as raw pipes of galvanized welded steel pipes used for low-pressure fluid transportation in addition to directly transporting fluids. 2. Galvanized welded steel pipe for low pressure fluid transportation (GB/T3091-1993), also known as galvanized electric welded steel pipe, commonly known as white pipe. It is used for conveying water, gas, air oil, heating steam, warm water and other general low pressure fluid or other uses of hot dip galvanized welding (furnace welding or electric welding) steel pipe. The wall thickness of steel pipe is divided into ordinary galvanized steel pipe and thickened galvanized steel pipe; The pipe end is divided into galvanized steel pipe without thread and galvanized steel pipe with thread. The specification of the steel pipe is indicated by the nominal diameter (mm), which is the approximate value of the inner diameter. It is customary to use inches, such as 11/2, etc. 3. Ordinary carbon steel wire bushings (GB3640-88) are steel tubes used to protect wires in industrial and civil buildings, installation machines and equipme
