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 Pipe and pipe fittings shall be the no-hub (MJ) or the hub and plain end design.
1.3 Pipe and pipe fittings shall be of the sizes specified in and and or other sizes that shall be permitted to conform to the requirements given herein.
1.3.1 PipeNo-hub (MJ) (Fig. 1).

4.1.4 Quantity.
4.1.5 Certification requirements.
4.1.6 Special packaging requirements (see Section 14).
4.1.7 Supplemental requirements desired, if any.
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 E 350. (For selected
detailed methods of analysis, see Specification A 518, 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) minimum for 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) maximum at a rate not to exceed 100°F (55°C)/15 min.
7.2.3 From 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.
9.1.4 No-hub pipe shall be cast in a single piece and conform to nominal dimensions shown in Fig. 1.
9.1.5 No dimension of hub/plain-end pipe shall exceed the tolerances specified in Table 1.
9.2 Fittings—All fittings shall conform to the nominal dimensions specified in applicable figures and be within the tolerances
specified in Table 2 for fittings listed in Figs. 2 through 34 or in Table 1 for fittings listed in Figs. 36 through 39.
10. Inspection
10.1 Inspection and Test by the Manufacturer—Pipe and fittings shall be inspected by the manufacturer prior to shipment.
Inspection by the manufacturer shall include all tests as specified herein. All tests and inspection with the exception of product
analysis shall be made at the place of manufacture unless otherwise agreed upon.
10.2 Inspection and Test by the Purchaser—The manufacturer shall afford the purchaser’s inspector all reasonable facilities
necessary to satisfy that the material is being produced and furnished in accordance with this specification. Foundry inspection by
the purchaser shall not interfere unnecessarily with the manufacturer’s operations.
11. Rejection and Rehearing
11.1 Material that shows unacceptable discontinuities as determined by the acceptance standards specified in the order,
subsequent to its acceptance at the manufacturer’s works, shall be rejected and the manufacturer shall be notified within 30 days
unless otherwise agreed upon.
12. Certification
12.1 Upon request of the purchaser, the manufacturer shall certify that his product conforms to the requirements of this
specification. The results of tests shall be furnished to the purchaser upon request as mutually agreed upon.
13. Product Marking
13.1 Each length of pipe and fitting shall be identified by the manufacturer’s name or identification mark. Marking shall be as
not to impair the usefulness of the part.
13.2 Samples that represent rejected material shall be preserved for a minimum of 2 weeks from the date of transmission of the
rejection report. In case of dissatisfaction with the results of the tests, the manufacturer shall be permitted to make claim for a
rehearing within that time.

SUPPLEMENTARY REQUIREMENTS
The following supplementary requirements are for use when desired by the purchaser. They shall
not apply unless specified in the order, in which event the specified tests shall be made by the
manufacturer before shipment of the castings.
S1. Transverse Bend Tests
S1.1 Transverse bend properties shall be determined from material representing each heat and shall meet the requirements
shown in Table S1.1. Properties thus measured shall be considered representative of the quality of the high-silicon iron but may
not represent properties in the actual castings.
S1.2Transverse bend tests shall be conducted in accordance with Test Method A438 except as follows:
S1.2 Transverse bend tests shall be conducted in accordance with the manufacturer’s established test procedure for transverse
bend test including the following:
S1.2.1 The specimens shall not be machined or ground and shall conform to the dimensions in Fig. 72.
S1.2.2 The specimens shall be cast in patterns in accordance with Fig. 73.
S1.2.3 The specimens shall be heat treated in accordance with Section 7.
A 861 – 04 (2008)
S1.2.4 The actual breaking load shall be reported. The requirements of Table 2 allow for any deviation due to variations in test
bar diameter. The deflection at fracture shall also be reported without correction.
S1.2.5 The rate of loading shall produce 0.025-in. (0.64-mm) deflection in 50 to 70 s. Continue loading at this rate until the
specimen fractures.
