Forming of Tube and PipeAll common forming operations such as bending,coiling and expanding can readily be performedon tube and pipe made by Special Metals. In gen-eral, material in the annealed condition is recom-mended. MONEL alloy 400, Nickel 200 and Nickel201 can be formed in the stress-relieved temper.However, the amount of deformation will be limit-ed by the higher tensile strength and lower ductil-ity. In bending, the minimum radius to whichstress-relieved tubing can be bent is 25 - 50%greater than for annealed tubing of the same size.

Bending and CoilingStandard methods of bending include ram orpress bending, roll bending, stationary-die bend-ing, and rotating-die bending. Tubing and pipe ofthe MONEL, INCONEL and INCOLOY alloys arereadily bent by any of these procedures.

An important precaution to observe in all bendingis to allow maximum radii to ensure that appliedstresses are as evenly distributed as possible. The minimum radii to which nickel alloy tubingcan be bent by various methods are given in thetable on this page which should be used as a guideto general limitations. Depending on equipmentdesign, tube size and quality of the finished bend,it is possible to bend to smaller radii than thoselisted. However, when smaller radii are necessary,trial bends should be made to determine if thedesired bend is possible.

Bending without Mandrels or FillersIn bending with no internal support, the diesshould be slightly smaller than those used with a mandrel or filler. Bending without use of a man-drel or filler is suitable only for tube and pipe thathave a wall thickness greater than 7% of the out-side diameter, or for bends of large radii. Nickelalloy tube in sizes within the above ratio can bebent with no mandrel or filler to a minimummean radius three times the outside diameter of the tube (3D) through 180 degrees.

Bending with Mandrels or FillersThin-wall tubing may be bent to small radii withoutwrinkling by use of a mandrel or filler. Thin-wall tubingin high nickel alloys may be mandrel-bent through 180 degrees to a minimum radius of 2D.

To minimize galling of the inside surface of the tube,mandrels should be made of hard alloy bronze ratherthan steel. Steel mandrels may be used but should bechromium plated to reduce galling.

Mandrels must be lubricated before use. Lubricants ofextreme-pressure, chlorinated oil are best for severebending. For less severe bending or for ease of removal,water-soluble lubricants are used.

Any of the standard filler materials such as sand, resin,and low-melting-point alloys may be used. Sand is the least desirable because it is difficult to pack tightlyand can lead to the formation of wrinkles or kinks during bending.

Low-melting-alloy fillers produce the best bends. Theirexpansion characteristics ensure that voids are elimi-nated and a sound center is created. Alloy fillers areremoved by heating the bent tube in steam or hotwater. Metallic fillers must not be removed by directtorch heating since they contain elements such as lead, tin, and bismuth which will embrittle the high-nickel alloys at elevated temperatures. It is imperativethat all traces of metallic fillers are removed before fabrication and service.

Forming of Tube and Pipe (continued)

Press BendingPress or ram bending, in which the tube is heldby two supporting dies and a force is appliedbetween the dies (see Figure 1), is normally usedonly for heavy-wall tubing where some flatteningis tolerable. This method does not provide closetolerances and is applicable only to large radiusbends. The bend is limited to 120 degrees, andthe radius of the bend should not be less than six times the outside diameter of the tube. A fillermaterial should be used if bends of radii less than 6 x OD are to be made.

Pressure blocks used in press bending should beat least twice the outside diameter of the tube inlength. Press bending with wing dies is used forunfilled, thin-wall, large-diameter tube.

Annealed tubing is not always preferred for pressbending. Annealed tubing of low base hardnessdoes not have sufficient stiffness to withstanddeformation without excessive flattening.Consequently, nickel and the MONEL nickel-copper alloys are usually press bent in the stress-relieved temper. The chromium-containingINCOLOY and INCONEL alloys have highermechanical properties in the annealed conditionthan nickel and the nickel-copper alloys andshould be press-bent in the annealed temper.Ideally, the choice of temper for a specific bend is determined by several trial bends.

Figure 3 – Stationary-die bending

Roll BendingRoll bending (Figure 2) is the principal method of producing helical coils, spirals, and circularconfigurations since an included angle of 360degrees can be obtained. Bending may be done on either unfilled or filled tube. The minimumbend radius for unfilled tube is approximately six times the outside diameter of the tube.

Stationary-die BendingStationary-die bending (Figure 3) utilizes a sta-tionary bending die and a movable pressure die.This method is not suitable for thin-wall tubingand is generally used with no mandrel support.

Stationary-die bending can produce bend radiidown to 2¹�₂ x OD but is normally used only forlarge-radius bends. The maximum included angle that can be produced is 180 degrees.

Rotating-die BendingRotating-die bending is the most common bend-ing process and is the preferred method for bending nickel alloy tube. The process is similarto stationary-die bending except that the bendingdie revolves and the wiper block remains stationary.

Rotating-die bending machines may have either a fixed wiper block (Figure 4) or a sliding wiperblock (Figure 5). The sliding wiper block is pre-ferred because it distributes the applied stressesmore evenly.

19

Tubing can be bent as much as 180 degrees witha minimum radius of 2 x OD by rotary bending.Although bending can be done without a mandrel,a mandrel is generally preferred and must be usedwhen the ratio of tube diameter to wall thicknessis above the limit suitable for bending withoutwrinkling or collapsing of the tube. Various typesof mandrel are used including ball and straight-plug types.

Expanding Heat-exchanger Tube

Tubing of the MONEL, INCONEL and INCOLOYalloys can be expanded into tube sheets by anyconventional method. Some design factors whichmust be taken into consideration in expanding orrolling tubing include thickness of the tube sheet,wall thickness of the tube, tube spacing or liga-ment between tube-sheet holes, rolling practice,clearance between tube and hole, and the relativehardnesses of the tubes and tube sheets. If anunfamiliar design is being used, trial tests shouldbe performed to determine if difficulties may beencountered in expanding.

The oversize allowance on tube-sheet holes to thenominal outside diameter of the tube should bekept to a minimum. The tube-sheet hole shouldbe 0.004 to 0.008 in (0.10 to 0.20 mm) largerthan the nominal outside diameter of the tube for tubing less than 1¹�₂ in (38 mm) OD. For largertubing the oversize-allowance should be 0.009 to0.010 in (0.23 to 0.25 mm).

Procedure

Expanding may be done by drifting with sectionalexpanders or, preferably, by rolling with three-roll expanders. The ends of rolled-in tubing areflared in the conventional manner.

The tube-sheet hole and both the outside andinside surfaces of the tube must be free of all matter such as oxide, dirt and oil. The ends of the tube should also be deburred before rolling.

Lubrication should be provided between therollers of the tool and the inside surface of thetube. Any sulfur-free mineral oil or lard oil, eitherdiluted or straight, may be used. Lubricants thatcontain embrittling or contaminating elementssuch as sulfur or lead should be avoided becauseof the difficulty of cleaning the finished assembly.

Controlled rolling equipment should be used toprevent over-expanding the tubes. Over-expand-ing may distort the tube sheet and plasticallydeform the tube-sheet ligaments, causing loose-fitting tubes. This is particularly true when thetube has a higher hardness than the tube sheet or a significantly higher work-hardening rate.

The tube sheet should be harder than the tubebeing rolled into it, otherwise springback in thetube may be greater than in the tube sheet, causinga gap between the two when the expanding tool isremoved. For that reason, tube sheets are usuallysupplied in the as-rolled or as-forged temper andtube in the annealed temper. It is particularlyimportant for the tube sheet to be harder thanthe tube when the sheet is thinner than the out-side diameter of the tube or when the tubes areclosely spaced. Tubes are closely spaced when the tube-sheet ligament is less than the greater of 25% of the outside diameter or ¹�₄ in (6 mm).

Stress-relieved tubing may be slightly harder than the tube sheet but can be expanded to forma satisfactory connection if greater care is exer-cised in expanding. For greater assurance of pres-sure tightness, a seal weld may be placed aroundthe end of the tube after expanding. The stress-relieved temper is suitable for either welding or silver brazing.

If rolling of stress-relieved tube appears to be amarginal operation, the problem can often beremedied by using annealed tube or stress-relieved tube with the ends annealed. Stress-relieved, end-annealed tubing combines thestrength advantage of stress-relieved material with the ease of fabrication of annealed material.Tubing in the annealed condition is used whenoptimum rolling or expanding characteristics aredesired or when severe cold-bending and flaringare to be done.

Miscellaneous Forming OperationsFlanging, bulging, swaging, and other expandingor reducing operations can be readily performedon tube and pipe of the high-nickel alloys. Manysuch operations are variations of those discussedin this section, and comments made on specificoperations will also apply to the variations.

Extremely severe or complex forming operationsmay require that the material be given one ormore intermediate anneals to prevent rupturingfrom excessive cold work.

Welding and FabricationFor many applications, the corrosion- and heat-resistant tubular products have to be fabricated and welded. The MONEL, INCONEL and INCOLOY alloy products are amenable to these processes. Full details on processes and techniques can be obtained from our website, www.specialmetals.com, or from any of ouroffices listed on the back of this publication.

Matched composition welding electrodes and filler metals are available for many of the tubularproducts. The main examples are listed below.Where a choice is indicated, the selection shouldbe made to suit the welding process and/or theservice conditions. Advice on the optimum selection is available.

Calculated Weights of Tubular ProductsThe table on page 23 shows calculated weights forcold-worked and extruded tubing and ASASchedule pipe, in lb/ft and kg/m. Note that, inpractice, small differences can occur due to varia-tions in dimensions within permitted tolerances.

Calculated WeightsTo determine the weight in pounds per linear footor kilograms per linear meter of seamless tube orpipe, use the calculations on page 23.

• When the O.D. is given, subtract the wall thickness from the O.D., multiply by the wall thickness, then multiply by the factors on page 23.

• When the I.D. is given, add the wall thickness to the I.D., multiply by the wall thickness, then multiply by the factors on page 23.

Service Pressure The ASTM tubing specifications do not includeany recommended service pressure or any elevat-ed temperature pressure requirements. However,throughout the tubing and pipe industry, Barlow’sFormula is commonly used to estimate the theo-retical internal bursting and working pressures oftubing.

Using this formula, reasonable estimated burstpressures can be calculated. Yield pressures canbe estimated as well by substituting “Y” (yieldstrength of material, psi) for “S” in the formula. A reasonable working pressure is derived bydividing the estimated burst pressure by 4, yielding a 4 to 1 safety factor margin.

Simply stated, Barlow’s Formula is:

P = 2 St / D

Where:

P = Burst Pressure, psi

S = Tensile strength of material, psi

t = Wall thickness, inches

D = Outside diameter, inches
