51 Steel Pipe Net Latest news: There are three main types of glass steel pipe production process: reciprocating fiber winding process, continuous fiber winding process and centrifugal casting process.
Reciprocating filament winding process (belonging to the fixed-length method): In this process, the dip tank is reciprocated with the rotating core mold, and the long fiber glass filament is subordinated to the core mold axis at a certain oblique angle, and the auxiliary angle (ie, The winding angle) is controlled by the ratio of the movement speed of the dipped tank and the rotation speed of the mandrel, and the translational movement of the dipped tank is controlled by computerized electro-mechanical control. The number of winding layers gradually increases until the wall thickness of the design is reached. After the winding is completed, the resin in the product is substantially cured. After solidification, the mandrel was removed from the glass-fiber reinforced plastic.
Continuous filament winding process (belonging to the continuous process): This process is a feeding station where the tube is moved through a resin-impregnated roving, pre-impregnated fiberglass and resin sand mixture, and the tube is continuously advancing in the core mold. Made in.
Centrifugal casting process (belonging to the fixed-length method): In this process, cut glass fiber reinforced material and sand are fed into the steel mold fixed on the bearing, and the unsaturated resin added with the catalyst is injected at one end of the steel mold. The impregnated reinforcing material, under the action of centrifugal force, replaces the air in the fibers and fillers, thereby producing a dense composite material without pores. Due to the effect of centrifugal force, the inner wall of the tube forms a smooth, smooth and resin-rich inner surface layer. Curing at higher temperatures. The tube made by this method is also called glass fiber reinforced sand tube.
There are many manufacturers in the world that use the reciprocating filament winding process to manufacture more than the other two production process manufacturers. One of the reasons is that the glass fiber reinforced plastic produced by the reciprocating filament winding process has a wider range of applications and has better applicability.
