(Specification)Standard Specification for High-Silicon Iron Pipe and Fittings
Standard Specification for High-Silicon Iron Pipe and Fittings
ABSTRACT
This specification covers high-silicon iron pipe and pipe fittings intended for corrosion-resistant service for both above- and below-grade construction. The castings shall be true to pattern, reasonable smooth, and free from defects that would make the castings unfit for the use for which they are intended. The material shall conform to the chemical composition requirements specified. All centrifugally cast high-silicon iron pipe shall be supplied in the as-cast condition. All other pipe and fittings shall be supplied in the stress-relieved condition; the stress relieving procedures are presented. Acid-proof joints for hub/plain-end pipe shall require the use of an acid-proof rope packing. No-hub pipe and fittings shall require a special acid resistant mechanical joint coupling. High-silicon iron pipe can be cut with either manual or hydraulic snap cutters. Hydrostatic testing shall be conducted on all castings.
SCOPE
1.1 This specification covers high-silicon iron pipe and pipe fittings intended for corrosion-resistant service for both above- and below-grade construction.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.3 Pipe and pipe fittings shall be the no-hub (MJ) or the hub and plain end design.
1.4 Pipe and pipe fittings shall be of the sizes specified in Table 1 and Table 2 and Figs. 1-71 or other sizes that shall be permitted to conform to the requirements given herein.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

5. Materials and Manufacture
5.1 The castings shall be produced by any established commercial practice applicable to high-silicon iron.
5.2 The castings shall be true to pattern, reasonably smooth, and free from defects that would make the castings unfit for the
use for which they are intended.
6. Chemical Composition
6.1 An analysis of each heat shall be made by the manufacturer from a test sample that is representative of the heat and that
is taken during the heat. A heat shall consist of all castings poured from a furnace or crucible melt without recharging new metal
into the furnace. The chemical composition thus determined shall conform to the requirements for the grade selected specified in
Table 3.
6.2 A product analysis shall be permitted to be made by the purchaser from material representing the heat. The chemical
composition thus determined shall meet the requirements specified in Table 3 or shall be subject to rejection by the purchaser.
6.3 Spectrometric or other instrumental methods and wet laboratory methods are acceptable for routine control determinations.
Any method employed shall give essentially the same results as reference methods listed in Test Methods E350. (For selected
detailed methods of analysis, see Specification A518/A518M, paragraph 6.4).
7. Heat Treatment
7.1 All centrifugally cast high-silicon iron pipe shall be supplied in the as-cast condition. All other pipe and fittings shall be
supplied in the stress-relieved condition.
7.2 Stress relieving shall be performed as follows:
7.2.1 Hold the casting at 1650°F (870°C)1650 °F (870 °C) minimum for 2 h 2 h plus an additional hour per inch of section
thickness for castings over 2 in. in thickness.
7.2.2 Cool the castings to 400°F (205°C)400 °F (205 °C) maximum at a rate not to exceed 100°F (55°C)/15100 °F (55 °C) ⁄15
min.
7.2.3 From 400°F (205°C)400 °F (205 °C) to ambient, the castings shall be permitted to be cooled in still, ambient air.
8. Joints
8.1 Acid-proof joints for hub/plain-end pipe shall require the use of an acid-proof rope packing.
8.2 No-hub pipe and fittings shall require a special acid resistant mechanical joint (MJ) coupling. One satisfactory coupling
consists of an inner PTFE sleeve surrounded by neoprene. The two-bolt coupling is made of 300 series stainless steel.
8.3 High-silicon iron pipe can be cut with either manual or hydraulic snap cutters. Field cuts shall be permitted to be readily
used with mechanical joint couplings to provide acceptable leak-proof joints.
9. Dimensions and Permissible Variations
9.1 Pipe:
9.1.1 Hub/plain-end pipe shall have a hub at one end and a plain end at the other and shall be cast in one piece (see Fig. 35).
9.1.2 Individual length of hub/plain-end pipe shall be either 7 or 5 ft nominal laying lengths as shown in Fig. 35.
9.1.3 Any deflections in the barrel of a single length of pipe shall not exceed ⁄16 in.
