Bodies, collars, collar sleeve bearings, and collar sleevcs shall be mide of heat-trcatcd alloy steel. 3.1.2 Mandre
10、ls and rolls. Mandrels and roils shall be made of tool steel, tempered and hardcncd to withstand ihc shocks and wear of regular usage. 3.1.3 Recovered materials. Unless otherwisc specified herein, all material and articles incorpornicd in the products covcrcd by this specification shall be new and m
11、ay be fabricated using rnotcriiils produced from rccovcrcd materials to the maximum extent practicable without jeopardizing the intcndcd use. The term “recovered materials“ means materials which have been collcctcd or rccovcrcd from solid waste and reprocessed to become a source of raw materials, as
12、 opposcd to virgin raw m;rtcrials. Nonc of the above shall be interpreted to mean that the use of uscci or rcbuil t products is allowed under this specification unless otherwise specifically specified. 3.2 Conslriiction. Expanders shall consist of a mandrel, body, collar, collar sleeve, collar slccv
13、c bearing. and rolls. Unless otherwise specified (see 6.2), expanders shall be righthand feed and have hrcc rolls. 2 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-E-15809D 3r 999990b 0528783 7 MIL-E- 1 SWD(NAVY) 3.2.1 Mandrel. The portion of th
14、e mandrel in contact with the rolls shall hitvc :i taper of 0.030 to 0.032 inch per inch of mandrel length. To prevent the expander body from remaining in the tube when the mandrel is withdrawn, the mandrel shall have a ihrcadcd cnd with nut, cxccpt that mandrels for 3B inch and smaller size expande
15、rs may use other means for mandrel rctcniion. The mandrels for 1/2 inch and larger size tube expanders shall be provided with cilhcr a In-inch square shank or a No. 1 Morse taper shank as specified (see 6.2). The mandrels or less than 3B inch size expanders shall be provided with a l/4-inch (0.240 t
16、o 0.245 inch) square machined on the last ln inch of a 5/16 inch round shank for a Jacobs chuck. The tapered length of thc mendrcl shall be ground to a surface finish of 32 RMS or smoother. Grinding shall remove all decarbonized metal and distortion from the tapered length of the mandrel. 3.2.2 Body
17、. The body shall be slotted to contain three taper rolls, set 120 degrces ;ipart, at a lead angle of 1/4 to 2 degrees, and shall have a threaded section on which shall be mounicd a collar, collar sleeve bearing, and sleeve, adjustable in position on the body so as to rcgulaic the dcpth of penetratio
18、n of the rolls into the tube, and secured by a lock nut or other posilivc mcins. The length of the body and threaded section on the body shall be tailorcd to the location and thickness of the tube sheet for which the expander is intendcd to be used relativc to ihc cnd of thc tube (see 6.2). 3.2.3 Co
19、llar. The collar shall be threaded internally to suit the threads on the hody. An antifriction type thrust bearing shall be mounted on the collar with a sleeve mounted on or made integral with the bearing. 3.2.4 Collar sleeve. The collar sleeve for single tube sheets or outer tube sheets on double t
20、ube sheet designs shall cover the small ends of the tapered rolls with the collar and locknut adjusted as close to lhe rolls as possible. The collar sleeve of all expanders over the 1/4-inch tubing size shall be recessed Ul-inch (plus 1/64 inch minus O) to fit over the end of the tuhc. The diameter
21、of the collar sleeve recess shall be not less than 1/32 inch larger than thc outside diameter of the tubes for which the expander is intended. 3.2.5 Rolls. The rolls shall have a taper which shall measure 0.015 to 0.016 inch pcr inch of roll length so as to produce parallel expansion of the tube. Th
22、e effcctive length of the rolls shall be such that, together with position adjustment of the collar, the expander will be suitable for rolling the tubes to within 1/8 inch of the inner face of the tube sheet (within 1/8 inch of each lace on an inner tube sheet), the thickness of which is specified,
23、or to the maximum depth specified (see 6.2). The rolls shall be ground after heat treatment to remove all decarbonized sled and distortion. Surface finish shall be 32 RMS or smoother. The rolls shall be arrangcd so ihat they will not fall out of the body unless the expander is disasscmblcd. When the
24、 mmdrcl is inserted to within 1/4 inch of the shoulder, the rolls shall not be body-bound. Rolls furnishctl with expanders designed to seat tubes in inner tube sheets or for use in retractive rolling sliiill be roundcd at cach end to prevent scoring the tube at the beginning and end of the rollcd sc
25、ction. Rolls furnished with expanders designed to seat tubes in outer tube sheets shall be rounded at the entrance end. 3 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-flIL-E-L58OSD 34 999990b 0528784 9 I 3.2.6 Sizes.
