Astm B725. Standard specifications for nickel and nickel-copper alloy welded tubes

Relevance

ASTM B725 specification includes welded tubes made of low carbon alloys: nickel alloys (N02200 and N02201), and monel-nickel-copper alloys (N04400), designed for use in harsh environments - high/low temperatures as well as chemical aggression.

Tube Processing

According to ASTM B725 specification, tubular products are welded and annealed or quenched and tempered prior to use. They are produced by welding without the addition of filler material. Afterwards, they undergo a cold finish to give them optimum corrosion resistance in the welded seam area.

Parameters

The ASTM B725 specification covers pipe with an outside diameter and nominal wall thickness according to the 5S, 10S, 40S chart in inches. Nominal pipe size is given in ANSI B36.19. Pipes, other parameters, may be manufactured and supplied to the customer provided the pipe meets all other requirements of the ASTM B725 specification. Note.Pipe wall thicknesses in the 5S and 10S schedules do not permit factory in-line production in accordance with the provisions of ANSI B1.20.1.

Standardization

Values specified in units of inch-pound are to be considered standard. Metric values, are mathematical conversions to SI units, which are provided for information only and are not considered standard.

Safety Data Sheet

This standard does not regulate safety measures relating to the operation of finished products. This is defined in the appropriate Safety Data Sheet (MSDS) for the product/material as provided by the manufacturer.

Use

Air conditioners, thermostats, heating systems.
