FAQS on 200mm steel pipe

Q: What are the common applications for 200mm carbon steel seamless steel pipe?

A: 200mm carbon steel seamless pipes are widely used in high-pressure fluid transportation, structural frameworks, and industrial piping systems. Their seamless design ensures superior strength and leak resistance. Common sectors include oil/gas, construction, and chemical processing.

Q: How does a flange 200mm connect to a 200mm steel pipe?

A: A 200mm flange is welded or bolted to the pipe end using compatible materials and standards like ANSI or DIN. Proper alignment and gasket selection ensure leak-proof connections. Flanges enable easy assembly/disassembly for maintenance.

Q: What advantages does carbon steel offer for seamless 200mm pipes?

A: Carbon steel provides high tensile strength, corrosion resistance, and durability under extreme temperatures. Its seamless construction eliminates weak joints, ideal for high-pressure applications. Cost-effectiveness and wide availability are additional benefits.

Q: Are 200mm steel pipes compatible with all flange standards?

A: Compatibility depends on matching pressure ratings and dimensions (e.g., ASME B16.5 or EN 1092-1). Always verify flange face type (flat, raised, ring-type) and bolt hole patterns. Non-standard pipes may require custom flanges.

Q: What distinguishes seamless 200mm pipes from welded alternatives?

A: Seamless 200mm pipes lack welded seams, reducing failure risks in high-stress environments. They offer uniform wall thickness and smoother interiors for efficient fluid flow. Welded pipes are cheaper but less suitable for extreme pressures.
