ASTM b725 pipe

What is ASTM B725?

99% nickel alloys are expensive and best for making pipes and tubes useful in missile operations. and for aircraft materials. Monel 400, with over 50% nickel and chromium, is suitable for high-strength and corrosion-resistance applications in many industries.

ASTM B725 is the specification standard for UNS N02200 and UNS N02201, which are pure wrought nickel commercially. Also, the specifications are for UNS N04400, which are Monel superalloys with high nickel and copper content. Manufacturers complying with these standards produce pipes with excellent electrical, thermal, and magneto-restrictive properties for use in many sectors.

Which pipes come under ASTM B725 specification?

High-performance pipes used for aerospace and missile operations come under the ASTM B725 specification. Also pipes used for many other sensitive operations comply with ASTM standards.

Hence the specifications, apart from mandatory requirements of correct composition, ensure that the OD or outside diameter and nominal wall thicknesses should be as per the Schedule 5S, 10S, and 40S in inches. Pipes that come under ASTM B725 specification include the following, among others.

  • UNS N02200 with 99% nickel, 0.15 maximum carbon, and others like manganese, copper, iron, silicon, and sulfur in less than one percent
  • UNS N02201 is similar to N02200 but with a further low carbon content of 0.02%
  • UNS N04400 with 60% nickel, 28-34% copper, and others in small quantities

Looking to buy ASTM b725 welded pipe? Check here with numerous Middle East importers the minimum order quantity and find out if it rusts in water.

Does ASTM B725 weld pipe rust in water?

The high nickel and low carbon ASTM B725 welded pipe does not rust in water. It is because of the over 99% nickel in UNS N02200 and N02201. Also, because of the high copper content of up to 34% in UNS N04400 with 60% nickel and other elements.

Welded pipes made per the ASM B725 specifications have low corrosion rates, even in rapid-flowing brackish or seawater. The automated welding process to make these pipes using no fillers make them not rust even in damaging environments.
