 Pipe cap is a product used to plug stainless steel pipes. It is a product used as a container after the end of the pipe or by welding two heads on both ends of a round pipe. Similar products include blind plates, caps, plugs, etc.

Alloy high-pressure thick-walled pipe caps are industrial pipe fittings that are welded on the pipe end or mounted on the external thread of the pipe end to cover and block the pipe. It is used to close the pipe and has the same function as the pipe plug. The convex pipe cap includes: hemispherical pipe cap, Oval caps, disc caps and spherical caps. Our caps include carbon steel caps, stainless steel caps, alloy caps, etc., which can meet your different needs.

Alloy high pressure thick wall caps also require control of the radius of curvature. Pipe caps have certain production standards and forms in actual production and production. In actual use, production and control are carried out in accordance with specific methods and principles to ensure that the produced pipe caps have certain outer diameter, inner diameter, wall thickness, etc. production standards and methods.

Alloy high pressure thick wall cap has the following characteristics:

1. Non-toxic and hygienic: it can be used for drinking water pipes. It is also non-polluting to the environment and can be recycled.

2. Corrosion resistance: It is resistant to corrosion by a variety of chemical substances, will not rust, and will not breed bacteria.

3. No scaling: The inner and outer walls of the product are smooth, the friction coefficient is only 0.007, the flow resistance is small, and the water delivery capacity is strong.

4. Light weight: easy to transport and install.

5. Beautiful appearance: This is inseparable from the perfect production technology and process.

Alloy high pressure thick wall cap technical parameters:

Diameter: DN15-DN1200
