the spiral fin tube type economizer
1.The introduction of product
This economizer is a newly type heat transfer equipment , consists of spiral fin tubes to overcome the inferior heat
efficiency and serious abrasion and short life than the bare economizer .
2.Material structure
Consists of a series of spiral fin tubes , the headers of inlet and outlet , bend ,frame and other auxiliaries .
3.Structure arrangement
in line /staggered arrangement
4.Characteristics
1.This type of economizer can largely develop the heat exchanging area than the bare economizer to add the heat
transfer area ,reduce the volume , compact structure and reduce the number of elbow and welding to make less
leakage and add the heat transfer efficiency .
2.Not easy to collect dust and the fume pass through the fin tube to form the boundary layer to occur the vortex to make less chance for the fly ash particle to touch the tube wall.
3.Widely temperature range , high pressure limit .
4.Durable strong impact ,reliable operation.
5.Less fume resistance ,reduced abrasion and long working life .
4.The standard for manufacture and inspection
JB/T6512 ( the technical specification for the boiler used H-F resistance welding spiral fin tube )
HG/T3181 ( H-F resistance welding for spiral fin tube)
JB/T6511( The technical specification for assembling the spiral fin tube channel )
JB/T1612 ( The technical specification for the boiler water pressure test )
JB/T1611 ( the technical specification for manufacturing the boiler tubes )
JB/1613 ( The technical specification for welding the boiler pressure parts )
Our Company is the professional and High–New enterprise for producing the Grade A boiler , and we have the
qualification for manufacturing Grad A boiler parts with large quantities of technical personnel . The company has the
large –sized workshop with the area of 60 thousand square meters and established a series of Labs , such as for
dynamic performance , chemical analysis, metallic phase test , balancing device and defects detection, also purchased
a batch of first rate equipment for production and test, such as NC small R heading double direction double R bend
auto production line , membrane wall auto production line, spiral fin tube auto production line and corrugated sheet
auto production line, also has high frequency resistance welder , 3-phase secondary rectification auto production
line for H-fin tube,auto sub-merged arc welder ,argon arc welder, heading type bending machine, large-sized NC
bending machine, hydraulic universal test machine , C and S combined analyzer,Richter scale hardness meter, X-ray defects detector , ultra-sound defects detector, impact test machine,hydraulic test equipment, and so on .
The Grade A boiler parts are manufactured strictly as the JB/T3375 to inspect the raw material . The main parts
produced including H-F resistance welding spiral fin tube, the spiral fin tube economizer , bare tube economizer ,
membrane economizer, coil superheater, re-heater , all types of distributing header ,water wall, convection tubes,
down tube and so on for the pressure tubes for boiler main body.
Shandong Hengtao Group lies in Gaomi city , Shandong province , which is the central region of Shandong peninsula .
Gaomi city faces Qingdao on the east and borders on the kite city Weifang on the west , the Jiaoji railway and Jiqing
Expressway pass it through, it is 60km away from Qingdao internatonal airport , so, we have the convenient traffic
and the apparent priority in location .
