Carbon Steel Cap

Our carbon steel pipe caps are forged and cast from standard carbon steel grades including Q235B and A106 Gr.B, built to fit seamlessly with ERW, seamless and spiral steel pipes across all common SCH wall thicknesses. We supply both butt weld and threaded end types, with surface finishes ranging from plain black bare steel to hot-dip galvanized or 3PE coated upon request for extra rust resistance. Strictly produced following ASTM and GB industrial standards, these end caps deliver reliable tight sealing to block fluid leakage in water supply, gas transmission, fire protection and municipal pipeline projects, and full material test certificates are available to support overseas engineering orders.
