Ordering Information4.1 Orderin
15、g for material under this specification shallinclude as a minimum the following information:4.1.1 ASTM designation, grade (see Table 3) and year ofissue.4.1.2 Description of the casting by figure number (see Figs.1 through 71) or by manufacturers drawings or catalognumber, or both.4.1.3 Length, diam
16、eter, and type of pipe and size and shapeof fittings.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 Manufacture5.1 The castings shall be produced by any establishedcommercial pract
17、ice 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 theuse for which they are intended.6. Chemical Composition6.1 An analysis of each heat shall be made by the manufac-turer from a test sample t
18、hat is representative of the heat andthat is taken during the heat. A heat shall consist of all castingspoured from a furnace or crucible melt without recharging newmetal into the furnace. The chemical composition thus deter-mined shall conform to the requirements for the grade selectedspecified in
19、Table 3.6.2 A product analysis shall be permitted to be made by thepurchaser from material representing the heat. The chemicalcomposition thus determined shall meet the requirementsspecified in Table 3 or shall be subject to rejection by thepurchaser.6.3 Spectrometric or other instrumental methods a
20、nd wetlaboratory methods are acceptable for routine control determi-nations. Any method employed shall give essentially the sameresults as reference methods listed in Test Methods E 350. (Forselected detailed methods of analysis, see Specification A 518,paragraph 6.4).7. Heat Treatment7.1 All centri
21、fugally cast high-silicon iron pipe shall besupplied in the as-cast condition. All other pipe and fittingsshall be supplied in the stress-relieved condition.7.2 Stress relieving shall be performed as follows:7.2.1 Hold the casting at 1650F (870C) minimum for 2 hplus an additional hour per inch of se
22、ction thickness forcastings over 2 in. in thickness.7.2.2 Cool the castings to 400F (205C) maximum at a ratenot to exceed 100F (55C)/15 min.7.2.3 From 400F (205C) to ambient, the castings shall bepermitted to be cooled in still, ambient air.8. Joints8.1 Acid-proof joints for hub/plain-end pipe shall
23、 requirethe use of an acid-proof rope packing.8.2 No-hub pipe and fittings shall require a special acidresistant mechanical joint (MJ) coupling. One satisfactorycoupling consists of an inner PTFE sleeve surrounded byneoprene. The two-bolt coupling is made of 300 series stainlesssteel.8.3 High-silico
24、n iron pipe can be cut with either manual orhydraulic snap cutters. Field cuts shall be permitted to bereadily used with mechanical joint couplings to provide ac-ceptable leak-proof joints.9. Dimensions and Permissible Variations9.1 Pipe:9.1.1 Hub/plain-end pipe shall have a hub at one end and aplai
25、n 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 either7 or 5 ft nominal laying lengths as shown in Fig. 35.9.1.3 Any deflections in the barrel of a single length of pipeshall not exceed316 in.2For referenced ASTM standards, visit

28、ures and be within thetolerances specified in Table 2 for fittings listed in Figs. 2through 34 or in Table 1 for fittings listed in Figs. 36 through39.10. Inspection10.1 Inspection and Test by the ManufacturerPipe andfittings shall be inspected by the manufacturer prior to ship-ment. Inspection by t
29、he manufacturer shall include all tests asspecified herein. All tests and inspection with the exception ofproduct analysis shall be made at the place of manufactureunless otherwise agreed upon.10.2 Inspection and Test by the PurchaserThe manufac-turer shall afford the purchasers inspector all reason
30、ablefacilities necessary to satisfy that the material is being pro-duced and furnished in accordance with this specification.Foundry inspection by the purchaser shall not interfere unnec-essarily with the manufacturers operations.11. Rejection and Rehearing11.1 Material that shows unacceptable disco
31、ntinuities asdetermined by the acceptance standards specified in the order,subsequent to its acceptance at the manufacturers works, shallbe rejected and the manufacturer shall be notified within 30days unless otherwise agreed upon.12. Certification12.1 Upon request of the purchaser, the manufacturer
32、 shallcertify that his product conforms to the requirements of thisspecification. The results of tests shall be furnished to thepurchaser upon request as mutually agreed upon.13. Product Marking13.1 Each length of pipe and fitting shall be identified by themanufacturers name or identification mark.
33、Marking shall beas not to impair the usefulness of the part.13.2 Samples that represent rejected material shall be pre-served for a minimum of 2 weeks from the date of transmissionof the rejection report. In case of dissatisfaction with the resultsof the tests, the manufacturer shall be permitted to
34、 make claimfor a rehearing within that time.14. Packaging14.1 Unless otherwise specified, the material shall be pack-aged in accordance with the suppliers standard practice andacceptable to the carrier at the lowest rates.

They shallnot apply unless specified in the o
36、rder, in which event the specified tests shall be made by themanufacturer before shipment of the castings.S1. Transverse Bend TestsS1.1 Transverse bend properties shall be determined frommaterial representing each heat and shall meet the requirementsshown in Table S1.1. Properties thus measured shal

38、mens shall not be machined or ground andshall conform to the dimensions in Fig. 72.S1.2.2 The specimens shall be cast in patterns in accordancewith Fig. 73.S1.2.3 The specimens shall be heat treated in accordancewith Section 7.S1.2.4 The actual breaking load shall be reported. Therequirements of Tab
39、le 2 allow for any deviation due tovariations in test bar diameter. The deflection at fracture shallalso 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 untilthe specimen fractures.TABLE S1.1 Transver
