Equipment acceptance

Pre-Acceptance

After the installation and shop commissioning of the equipment, notify the customer to send persons to the supplier's facility for pre-acceptance, pre-acceptance for the following content:

a)  Check that the physical object of the equipment meets the requirements of the technical agreement;

b)  whether the appearance of the equipment is clean, whether the equipment pipeline connection is strong, the structural parts meet the requirements;

c)  Whether the equipment has gas leakage or water leakage;

d)  Whether the equipment parameters are fully functional;

e)  Check that the equipment is operating properly and reliably;

f)   Inspection of the scope of supply and the integrity of factory technical documents;

g)  Welding the analog parts at the supplier site.

Final Acceptance

After the equipment arrives at the customer site, notify the supplier, the supplier sends personnel to the customer site for final acceptance, final acceptance of the following content:

a)    Equipment installation, commissioning completed, simulating operation without fault.

b)   Train welders in practical operations and explain the precautions for the use of equipment.

c)    Carryout test piece welding, the test pieceshall be provided by the customer. Suppliershall guide the actual operation  of  the  customer  personnel,  complete  the  simulation  parts  welding  to  meet  the  technical agreement requirements, the two sides shall sign the final acceptance minutes of equipment..

Guarantee period and after-sales service:

     After-sales technical services and spare parts supply is supplier's responsibility;

     Supplier shall implement quality assurance on the product under normal conditions of use, and from the date of  the  final  acceptance  signature,  Supplier  shall  guarantee  the  equipment  for  12  months  (except  for consumables and man-made damage).
