Carbon steel welded pipe caps, also known as pipe plugs, pipe caps, pipe covers, mufflers, are used to close the pipeline, the role is the same as the pipe plugs, but the caps can be screwed directly onto the pipeline without other accessories. Pipe caps include convex caps, conical shells, reducer segments, flat caps and tight port designs. They serve the same purpose as pipe plugs, effectively closing off the pipeline. The pipe end cap, depending on the material, can be made of carbon steel, stainless steel, alloy steel, or other materials. It is designed to effectively seal the pipe, just like pipe plugs.
| Advantage
Wide Application
Currently in the market, there isawide range of pipe caps which are widely used in the petrochemical, nuclearmedical eauipment, shipbuilding, wastewater treatment and pipeline industries. The use of welded pipe caps inengineering projects not only improves the sealing of pipes, but also enhances worker safety.
Superior Sealing Performance
Butt-welded stainless steel end caps are fittings welded to the end of a steel pipe to cover the pipe. The weldedstructure has high stifness and good integrity. At the same time, it is easy to ensure gas and water tightness, so itis particularly suitable for the manufacture of high-strength and high-stiffness hollow structures, such as pressurevessels and pipelines.
High-quality manufacturing
Butt-welding technology facilitates the welded assembly of plates, profiles or castings and is thereforeimportant for the manufacture of large and very large structures such as bridges, ships and rockets. lt is alsopossible to join different shapes, sizes and even materials using welding processes, thereby reducing weight, savingmaterials and optimizing resources.

| Q & A
Q: What are carbon steel pipe caps used for?
A: Carbon steel pipe caps, also known as pipe plugs or pipe covers, are used to close off pipelines.
Q: How do carbon steel pipe caps differ from pipe plugs?
A: While the role of carbon steel pipe caps is the same as pipe plugs, the caps can be directly screwed onto the pipeline without the need for additional accessories.
Q: What are the different designs of carbon steel pipe caps?
A: Carbon steel pipe caps come in various designs, including convex caps, conical shells, reducer segments, flat caps, and tight port designs. These designs cater to different pipeline requirements and ensure effective closure.
