    Threading Galvanized Steel Pipes With Couplers

    The process of thread&screwed treatment : The manufacture of pipe hoops is the most delicate, is the focus of the whole product, because it is the whole project, is the part of a large amount of pressure.The material requirement of tube hoop is higher than or equal to the material of seamless steel tube itself.After the round steel is blanked, the size is fixed by lathe processing, then the thread is processed, and finally the thread and size are tested.

    Galvanized steel is a kind of special steel material. It USES special technology to combine the elements of zinc and iron to produce a brand new galvanized steel material.Many excellent features of galvanized steel, hot galvanized steel coating uniform, strong adhesion, so the service life will be very long。 Galvanized steel composition Iron is the main component of steel. The difference between iron and steel is the difference in carbon content. Iron has lower carbon content, so it has better toughness and hardness。

    ASTM A53 GrB Galvanized Pipes For Gas And Water

    Seamless Pipe : 1. The tube billet shall be rolled for three consecutive rolls at first, and the diameter test shall be carried out after extrusion. If the surface does not respond to the crack, the round tube shall be cut by the cutting machine. 2. Then enter the annealing process. During annealing, acid liquid should be used for pickling. 3. After the quality inspection, it shall be strictly selected by hand by the staff, and the surface shall be coated with oil after the quality inspection. 4. If the hole diameter is too large, it shall be straightened. After straightening, it shall be sent to the flaw detector by the transport device for flaw detection experiment, and finally it shall be labeled and placed in the warehouse after specification arrangement.

    Galvanized Water Pipes and Plumbings

    The biggest role of hot galvanizing is to prevent the object rust, as we all know, no matter what product rust will reduce its service life, rust corrosion of the object's own material speed is particularly fast, so after hot galvanizing, the product will not rust, naturally increase the product's use time.Object galvanized after the product will be more beautiful, and not galvanized surface uneven color is not good, zinc is silver, so galvanized after the product looks more clean, beautiful. The unique advantage of hot galvanizing is that it is more environmentally friendly and pollution-free for the environment, and it costs less, and save time and labor, to provide people with more time, energy and money.
