Steel pipe caps are used to close pipes and serve the same purpose as pipe plugs. The form of the blind plate is similar, except that the blind plate is removable and the welded pipe cap is not removable. The design of the pipe cap includes a convex pipe cap, a cone shell, a reducer section, a flat cap and a tightening mouth. The characteristics of the pipe cap: 1, health, non-toxic: This product is a green building material, can be used for pure drinking water pipeline system. 2, heat resistance: under the specified long-term continuous working pressure, the water temperature of the pipeline can reach 95â??. 3, corrosion resistance, no scaling: can eliminate the pipe scaling blockage and basin, bathtub yellow rust. 4, heat preservation and energy saving: thermal conductivity is only metal.
