Ottoman is fully equipped with an advanced and integrated quality control system to produce tubes to exacting national  and international standards. The Quality Control system is backed by the services of a modern laboratory and a test house  for physical and chemical tests.

 Ottoman is an ISO 9001 Certified company and is currently working towards attainment of
 ISO TS 16949 Certification.

 Some of the important Quality Control measures used for manufacturing are:

 
     
   
 
Ottoman is equipped with technofour Eddy Current Testing Machine. This non destructive testing equipment is capable of identifying defects both in the parent material and in the weld zone according to the specification to which the tubes have been manufactured. It is also capable of giving an audio-visual indication, coupled with automatic segregation facilities. The equipment is specially useful for ensuring the quality of CDW tubes to exact specifications.
 
     
   
 
In order to measure the suit ability of products to various design and fabrication requirements, a number of manipulation tests are carried out. These include such deformation tests as flattening, flaring, flanging, expansion, crushing, bending & reverse flattening. These tests indicate the ability of the weld, as well as parent material, to withstand forming operations. Some of the other tests which are carried out are:
 
  Tensile Tests
  Bending Tests
  Crushing Tests
  Flaring Tests
  Flattening Tests
  Dimensional Tests
  Straightening Tests
  Visual Inspection Tests
Chemical Analysis Tests
