Packaging of Monel 400 Tube:

Shanghai Metal Products are packed and labeled according to the regulations and customer's requests. Great care is taken to avoid any damage which might be caused during storage or transportation. In addition, clear labels are tagged on the outside of the packages for easy identification of the product I. D. and quality information.

1) Shanghai Metal Standard

2) Customization

Q1.How long does sample preparation take?

A: For stock sizes: 3–7 working days. For custom OD, wall thickness or cut length: 15–20 working days.

Q2.What information do you need for a quotation?

A: Outside diameter, wall thickness, length, quantity, condition (annealed or cold-drawn), end finish (plain, beveled or grooved), standard (ASTM B165), and destination port.

Q3.What is the MOQ and lead time?

A: MOQ is 50 kg for stock sizes and 200 kg for custom sizes. Standard orders ship in 15–25 working days; customized orders take 25–40 working days.

Q4.What quality standards and certifications are available?

A: Tubes are manufactured per ASTM B165 / ASME SB165 and supplied with Mill Test Certificate EN 10204 3.1, including chemical composition and mechanical test reports.

Q5.For a seawater heat exchanger, should I choose seamless or welded Monel 400 tube?

A: Choose seamless, annealed, OD 19–25 mm × 1.2–1.5 mm wall. The welded seam is a potential corrosion initiation point under continuous seawater exposure, while seamless tube offers full wall uniformity.

Q6.Can Monel 400 tube replace 316L stainless in a hydrofluoric acId line?

A: Yes. 316L suffers rapid pitting and stress corrosion cracking in aqueous and anhydrous HF. Monel 400 is one of the few standard engineering alloys compatible with HF vapor and liquid, so use seamless, cold-drawn tube per ASTM B165.

Q7.Is Monel 400 tube suitable for LNG or −200°C cryogenic servic?

A: Yes. It retains high toughness and low magnetic permeability down to −200°C, whereas carbon steel and some austenitic stainless steels become brittle. Use seamless, bright annealed tube for fuel and bleed-air lines.
