6 AAA SUPPORTS PRIVATE LIMITED GUARANTEE Each and spring support /hanger assembly is guaranteed for a period of 18 month from the date of supply or 12 months from the date of coissioning, whichever is earlier. We shall replace with free of charges if any materials, which owing to defect in raw materials or workmanship, should fail within guaranteed period. INSTALLATION INSTRUCTION Fix the spring support in accordance with your pipeline drawing maintaining Tag No. if required adjustment can be made by twisting turnbuckle for hanging type or threaded load column pipe for bottom supported type, till if comes to the mark indicating the pre-setting cold load. All variable and constant spring supports are locked in cold/pre-set load. Variable spring supports are locked by side studs & nuts from either side for constant spring supports by a pin, both of which are indicated by an arrow mark. After application of the hydrostatic load and before the pipe line comes into operation, pre-set locking arrangement are to be removed to take care of thermal movement & pipe load. Height adjustment by twisting of turnbuckle or threaded load column pipe should not be made in loaded condition. Erection & pre-set removal instruction writ up are pasted separately on variable and constant spring box.

7 AAA SUPPORTS PRIVATE LIMITED VARIABLE SPRING SUPPORT Variable Spring Supports are used where pipeline are under high pressure, high temperature and results in vertical movement. To allow vertical movement, the entire loads are taken care of by Variable Spring Supports in both the hot and cold position. The Variable Spring Supports are utilized to protect valuable instrument, pipeline a critical component. The designs of the Variable Spring Supports are based on loads, movements and modals to suit the required position on pipelines and also depending on the weather condition.

8 AAA SUPPORTS PRIVATE LIMITED TYPE-A TYPE-B TYPE-C TYPE-D TYPE-E TYPE-F TYPE-G RANGE We offer three series prefixed VS1, VS2 & VS3 twenty-five spring sizes allow a range of load 8.2kgs to tons. In all the series VS1, VS2 & VS3 provide travel 40, 80& 160 respectively. It also takes 5 co-liner displacements. We offer models such as A, B, C, D, E, F, G and for corrosion resist supports AC, BC, CC, DC, EC, FC & GC. SPECIAL RANGE/DESIGN Apart from our standard design and product range, we undertake jobs specially designed by us to suit Clint s requirement to avoid corrosion. We offer PU or neoprene rubber coating on spring and epoxy painting/galvanizing. DESIGN PRINCIPLES Supports components are arranged in a series of load groups, the load within each load group is in strict accordance with the permissible load of the connecting thread. All supports have a strictly syetrical shape; have single upper and lower load connection resulting a moment free load connection to the structure. The actual travel position of the hangers/supports can be read directly from the travel scale in in accordance with the actual travel. All hangers/supports can be blocked in installation position within a close raster. SUPPLY STANDARD All hangers/supports have a rivet on name plate with travel scale displaying series, size, type, hot load, cold load, travel and client s tag no.

9 AAA SUPPORTS PRIVATE LIMITED METHOD OF SELECTION (VARIABLE) Ordering information Hot/Operating load = 2000Kg Movement/Travel(Vertical) = Maximum Load Variation(V) = 25% Using Selection Table Enter table at 2000 Kg. located in size 15 column 20 UP check Movement spring rate*100 = variability(v) hot load From VS2 series of size 15, Spring Rate =13.0 Kg/ Variability(V) = 20*13* = 13.0% (acceptable) Selection/Support Designation = VS2-TYPE-15 Cold/pre-set load = hot load+(movement*spring rate) = 2000+(20*13)=2260 Kg.

16 AAA SUPPORTS PRIVATE LIMITED CONSTANT SPRING SUPPORT Constant spring support is specially used to accoodate constant effort load, excessive movement of the pipeline due to high temperature and pressure of thermal movement. Constant load takes place through its range by a perfect counter balance crank lever where load and spring movements through the pivot ensure the minimum kinetic variation. TYPE-A TYPE-B TYPE-C TYPE-D TYPE-E TYPE-F

17 AAA SUPPORTS PRIVATE LIMITED RANGE We offer twenty size of group A, B & C and three series prefixed CS-1, CS-2 & CS-3 for both horizontal and vertical modal. Twenty sizes Constant spring support allows a load range from 25Kg. to 13000Kgs. And maintains a travel range upto 330. SPECIAL RANGE/DESIGN Apart from our specified standard design and range of product, we undertake jobs specially designed by us to fulfill client s requirement i.e. constant spring support can supply more load/travel than that provided in our standard selection table. Special type of fixing arrangement can be designed apart from our standard. LOAD ADJUSTMENT The load adjuster allows for an increase or decrease of load carrying capacity of plus or minus 10 percent of the mean load. Rotating the load adjuster nut in the appropriate direction will increase or decrease the load accordingly. OFF-SET It also takes 5 co-linear displacement PRE-SETTING Each and every Constant spring support is pre-setted prior to dispatch. The pre-set pin must be removed before the entire system comes into operation and following the erection instruction. SAFETY DEVICE Double fold action Travel Stops for controlling the required travel as well as resisting excessive load creating impact on the support is provided in each and every Constant spring support. INDICATOR & REFERENCE MARK Each Constant spring support is provided with a travel indicator, which indicates the position of movement of the pipeline. I.e. low, medium and high. An elaborate introductory plate is also provided on the surface of the support, which indicates client reference mark/tag no., operating load, total travel, our reference etc.
