Product Description

Carbon steel pipe cap, also known as plug, cap, pipe cover, bulkhead, is used to seal the pipeline, which has the same function as the pipe plug, but the cap can be directly screwed on the pipe without other pipe fittings. The pipe cap includes the design of convex pipe cap, conical shell, reducing section, flat cap and tight mouth.

The steel pipe cap is used to close the pipeline, with the same function as the pipe plug. The forms of blind plates are similar, except that blind plates can be removed for plugging, while welded pipe caps cannot be removed. The pipe cap includes the design of convex pipe cap, conical shell, reducing section, flat cap and tight mouth. It is used in pressure vessel equipment in petrochemical, atomic energy, food and pharmaceutical industries


1. Hygienic and non-toxic: This product is a green building material, which can be used in the pure drinking water pipeline system.

2. Heat resistance: under the specified long-term continuous working pressure, the water temperature transported by the pipeline can reach 95 ℃.

3. Corrosion resistance and no scaling: it can eliminate the worries of scaling and blocking of pipes and yellow spot rust of water basins and bathtubs.

4. Heat preservation and energy conservation: the thermal conductivity is only metal.
