Data is like Art, it is subjective and open to interpretation!  It is very important that one understands the represented data, numbers and statistics to avoid misinterpretation. 

Need for Breaking Load in LPG Conveyor Chains

LPG Conveyor chains are assembled and installed in hundreds and thousands in numbers at a time. The strength of the chain assembly is dependent on the strength of its weakest member link. Thus, it is extremely important that manufactured chains are randomly tested for breaking load or some form of rupture test.

JASMA manufactured Chain links undergo a pre-defined cadence of breaking load tests as per our product quality requirements; this ensures our products are of the highest quality and reliability in the real-world.

Conducting Load Test using Single Strand Method

Typically, during a load test, a pre-defined number of links are assembled and a gradual pull load is applied, the point at which break occurs is the load of breakage. Test method setup image shown as “Single”.  This breaking load is reported either in KN or KgF. All manufacturers report a minimum breaking load value. For example, JASMA F801 chains achieve a minimum breaking load of 6300 KgF.

Loop Method

In the method described above (“Single” method), a single assembly of chain links are tested. Now, if we make a loop of the links, and test the same links again (setup illustrated below), lets call it the “Loop” Method. We achieve more than double (2x) the breaking load.

While both links used are from the same manufacturing batch and have same chemistry and other parameters, it is interesting to note that just the variation in test method dictates what breaking load is achieved.  Double breaking load of the chains can be easily reported by simply using the “Loop” method of testing.
