DTC Stainless Steel Pipe End Cap | Butt‑Weld Tube Cap Head

Product Overview

DTC stainless‑steel pipe end cap is a butt‑weld pipe fitting designed to seal and close the end of a pipeline. Manufactured from premium 304 or 316L stainless steel with precision forming, our end caps provide reliable leak‑proof sealing for pipe ends — making them essential for water supply, oil & gas, chemical processing, food‑grade sanitary and industrial piping applications requiring corrosion‑resistant pipe end closure.

Core Product Advantages

• Premium Stainless Steel: 304/304L and 316/316L grades for excellent corrosion resistance
• Reliable End Sealing: Butt‑weld connection creates a permanent, leak‑proof pipe end closure
• Smooth Surface Finish: Polished surface for sanitary and clean‑in‑place applications
• Precision Dimensions: Tight tolerances ensure perfect pipe alignment and fit
• Seamless & Welded Options: Both seamless and welded construction available
• Various Cap Styles: Elliptical, hemispherical, flat and conical cap options

Available Cap Types

• Elliptical Cap (EHA/EHB) — most common type, standard pressure rating
• Hemispherical Cap — for high‑pressure applications
• Flat Cap (Flat Head) — for low‑pressure applications
