1. Check the hoisting tools of crane before loading  SSAW steel pipe . If it is a hook hoisting, select a special U-shaped hook to avoid damaging the nozzle and anti-corrosion layer. 2. Using rope to control the balance of SSAW pipe in the process of loading, to avoid the swaying of the pipe body and the collision and damage to the pipe. 3. Strengthen the management of SSAW pipe loading and unloading. Loading and unloading the pipe whould be command by a special person,  to prohibited to prying, rolling, sliding and other ways to damage the anti-corrosion layer of pipe. Changsha Xiangjia Metal Materical Co., Ltd.  the Steel Pipe Division of ADTO GROUP, is one of the leading manufacturers of steel products in China. We specializes in manufacturing all kinds of steel pipe in various grades and sizes. Years of production experience and manufacturing facilities who have a capacity of 200,000 tons per annual will ensure the good quality and competitive duration of our products.

  Galvanized steel pipe   is a carbon steel pipe coated with zinc layer. It should be noted that the groove size and handle the nearby galvanized layer before welding. In order to weld penetration, the groove size should be 60~65°, and left 1.5~2.5mm gap. In order to reduce the penetration of zinc to the weld, the galvanized layer in the groove shoule be remove before welding to avoid air bubbles, trachoma, and false welding. The welding rod should be selected according to the base material of the galvanized steel pipe. Generally, the selection of J422 is good choice for low-carbon steel pipe due to the ease of operation.

SSAW steel pipe , a pipe in which the weld is helically distributed relative to the axis of the pipe body. Used for conveying pipes, pipe piles and structural pipes. Product specifications: outer diameter 300-3660mm, wall thickness 3.2-25.4mm. The characteristics of SSAW steel pipe are: 1. The same width strip can be used to produce pipes with different outer diameters; 2. The pipe has good flatness and precise dimensions. The spiral weld increase the rigidity of the pipe, so there is no need for sizing and straightening after welding; 3. Easy to realize mechanization, automation and continuous production; 4. Compared with other equipment, it has small dimensions, land occupation and investment are smaller; 5. Compared with the straight seam welded pipe of the same size, the weld of SSAW steel pipe per unit length of the pipe is longer, so the productivity is lower.
