14、ubless joined by a coupling.4. Ordering Information4.1 Ordering 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 manuf

15、acturers drawings or catalognumber, or both.4.1.3 Length, diameter, 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

16、 castings shall be produced by any establishedcommercial 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 theuse for which they are intended.6. Chemical Composition6.1 An analysis of eac

17、h heat shall be made by the manufac-turer from a test sample that 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 c

18、onform to the requirements for the grade selectedspecified in 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

19、thepurchaser.6.3 Spectrometric or other instrumental methods and 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 Spec

20、ification A 518,paragraph 6.4).7. Heat Treatment7.1 All centrifugally 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 1650

21、F (870C) minimum for 2 hplus an additional hour per inch of section 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 a

22、ir.8. Joints8.1 Acid-proof joints for hub/plain-end pipe shall 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

23、 coupling is made of 300 series stainlesssteel.8.3 High-silicon 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:

24、9.1.1 Hub/plain-end pipe shall have a hub at one end and aplain 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 pip

25、eshall not exceed316 in.9.1.4 No-hub pipe shall be cast in a single piece andconform to nominal dimensions shown in Fig. 1.9.1.5 No dimension of hub/plain-end pipe shall exceed thetolerances specified in Table 1.9.2 FittingsAll fittings shall conform to the nominaldimensions specified in applicable

Inspection10.1 Inspection and Test by the ManufacturerPipe andfittings shall be inspected by the manufac

28、turer prior to ship-ment. Inspection by the 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 a

29、fford the purchasers inspector all reasonablefacilities 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

30、.1 Material that shows unacceptable discontinuities 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 r

31、equest of the purchaser, the manufacturer 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 thema

32、nufacturers name or identification mark. 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 test

33、s, the manufacturer shall be permitted to make claimfor a rehearing within that time.14.

They

35、 shallnot apply unless specified in the order, 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

36、Table S1.1. Properties thus measured shall beconsidered representative of the quality of the high-silicon ironbut may not represent properties in the actual castings.S1.2 Transverse bend tests shall be conducted in accordancewith the manufacturers established test procedure for trans-verse bend test

37、 including the following:S1.2.1 The specimens 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

38、shall be reported. Therequirements of Table 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 untilt

39、he specimen fractures.S2. Hydrostatic TestingS2.1 Hydrostatic tests at 40 psi, minimum, shall be con-ducted on all castings specified in the order. Any leak revealedby this test shall be cause for rejection for the individual piece.A leak shall include any evidence of moisture on the outsidediameter
