airetool tube removal tools jsp manual tube puller boiler expanders manual tube puller provides economical method for tube removal features and benefits easy to use ­ inserting the spear into the tube and removing the tube requires only a hand wrench no external power ­ manual operation eliminates the need for air or electricity making the tube puller ideal for field service applications durable ­ major components are machined from high quality high strength steel heat-treated for extra long service life easier close-quarter operation ­ hex at back of spear allows the spear to be tightened into tube without disassembly of the thrust mechanism clearly marked sizes both spear and thrust collar are marked with tube size for a quick matching of tool to job wide selection of sizes ­ specific pullers are made for 1/4 3/8 1/2 5/8 3/4 7/8 and 1 inch o.d tubes to match most popular applications tube expanders tube expanding is the art of cold working the ends of tubes into intimate contact with the metal of the containing tube holes to form a leak proof mechanical seal and/or joint in other words it is a mechanical method of establishing a mechanical joint between a tube and a tube hole airetool manufactures condensed/heat exchanger expanders boiler expanders furnace expanders and many special application expanders tube expanders consist of mandrel ­ a tapered pin through the center to which the power is attached and when advanced pushes the rolls against the tubes rolls ­ a set of 3 or more of tapered cylindrical parts which are driven by mandrel and contact the tube wall to be expanded the taper on the rolls is in the reverse direction and one-half the taper of the mandel if it is a parallel roll expander cage ­ this is the expander body or housing since it holds the mandel and rolls in place the slots which contain the rolls also provide a feed angle which helps pull the mandrel in to provide expansion of the rolls mandrel rolls and cage are the three things common to all expanders other parts added further classify the type of expander thrust assemby ­ this assembly attaches to the cage and allows adjustment of the expanding depth the thrust collar will remain stationary against the tube sheet or tube end while the cage mandel and rolls expand the tube a thrust assembly is used on condenser/heat exchanger expanders some furnace expanders and special boiler expanders flare or bell rolls ­ this type roll is added to the back of the cage on boiler or furnace expanders to flare the tube end after it has been expanded b-1000 series b-2000 series tube size od

2987534 2986901 2986902 2986903 2987209 b-3000 series boiler expanders when a condenser/expander is selected and ordered it comes complete with mandrel but a boiler expander does not come with a mandrel because of the nature of their application it is possible to obtain them with three types of mandrels header mandrel ­ this is the longest mandrel because it has an extension as part of the mandrel to allow you to reach through manifolds or header boxes drum mandrel ­ this mandrel is used when you are expanding inside the boiler drum and can get to the tube at the end short series mandrel sets ­ there are times when the space in a boiler will not allow use of the longer header or drum mandrels the short series sets allow you to expand the tube in different steps when space is restricted if you would take the tapered portion of the header or drum mandel cut it in several pieces and add a drive to each section you would have a short series set b-2000 series expander ­ the b-2000 series boiler expanders have three expanding rolls and three flaring rolls that are self contained in the cage an exclusive thrust mechanism makes torque control possible for boiler tube rolling the b-2000 series expander is available for sizes 1 o.d thru 4 1/4 o.d tubes with drum thickness of 1/2 thru 2 3/4 thick short series mandrels are available b-3000 series expanders ­ the b-3000 series expander has three expanding rolls and a thrust mechanism the b-3000 expander is available for 1 1/4 o.d thru 4 1/4 o.d tubes it is for use as a straight rolling expander in fire tube boilers and as a second operation expander in thick drums thru 5 3/8 thick b-1000 series expanders ­ the b-1000 series expander is the same basic expander as the b-2000 but without the thrust mechanism it is available for 1 o.d thru 4 1/2 o.d tubes with drum thickness from 1/2 thru 2 3/4 thick short series mandrels are available the b-1000 expander can be used when torque control is not desired or where space is limited such as in a small diameter header the b-1000 expander can be converted to a b-2000 type expander by adding a thrust mechanism should the need for torque control arise airetool offers several different configurations of the above type expanders for special applications when selecting a boiler expander you must know tube od tube wall thickness or bwg tube sheet or drum thickness minimum straight section at end of tube drum diameter if less than 18 this information will allow you to select the proper type boiler expander and mandrels some items are available on quotation basis only additional sizes are available contact customer service for details 54 55
