FAQS on metal pipe

Q: What are common applications for 32mm metal pipes?

A: 32mm metal pipes are widely used in plumbing systems, structural frameworks, and industrial machinery due to their balance of strength and moderate diameter. They work well for water/gas distribution and lightweight support structures.

Q: How does a 3/4 inch metal pipe compare to metric sizes?

A: A 3/4 inch metal pipe has an outer diameter of approximately 26.7mm, close to 27mm metric sizing. It's commonly used in HVAC systems and low-pressure hydraulic applications where compact sizing is required.

Q: What materials are best for 3 inch metal pipes in corrosive environments?

A: Stainless steel (304/316 grade) or galvanized steel are ideal for 3 inch metal pipes exposed to corrosion. These materials resist rust and chemical degradation while maintaining structural integrity under high-pressure conditions.

Q: Can 32mm metal pipes be threaded for fittings?

A: Yes, 32mm metal pipes can be threaded using standard pipe threading tools. Ensure wall thickness exceeds 2mm for safe threading without compromising structural stability.

Q: What factors determine choice between 3/4 inch and 3 inch metal pipes?

A: The decision depends on flow requirements (3 inch for high-volume systems) and space constraints (3/4 inch for tight installations). Pressure ratings and structural load capacity also influence sizing selection.

  • Elbow

    Elbow

    Carbon Steel &stainless Steel Elbow Elbows are pipe fittings used to change the direction of pipelines in piping systems, commonly employed at pipeline bends. They are widely used in industries such as petroleum, chemical, and power. The common size range for elbows is DN15-DN2000, and typical angles include 45°, 90°, and 180°.

  • Pipe Cap

    Pipe Cap

    Pipe caps come in different shapes, including round, square, and oval, and can be designed for both threaded and welded connections. They ensure the integrity of piping systems during transportation, storage, and installation by protecting the pipe ends from dirt, debris, and environmental factors. Durable and easy to install, pipe caps are critical for maintaining system efficiency and safety.
