National standard for sampling method of GB/T 2289 "coking viscous oil product sampling method".
The tanker sampling tube sampling, the weight lifted, make sampling tube perpendicular to the surface, slowly the sampling tube bottom intrusion to the tanker, close the heavy weight, then lift the sampling tube. Wipe the surface oil with a veil, and then take the style into a clean, dry container. The total amount should not be less than 2000ml.
Choice: 1: Material: stainless steel SS304; specification of 32 x 3200mm at the bottom of the heavy weight can lead to the top rope
2: Material: glass, brass; specification of 32 x 3200mm at the bottom of the heavy weight can lead to the top rope
3: Material: brass; specification of 32 x 3200mm at the bottom of the heavy weight can lead to the top rope
Note: the sampling device of the export pipeline should be set up to ensure that the samples should be representative.
Tank or the cabin when sampling, the tank gas pressure or cabin pressure should be normal or close to normal pressure.
Sampling should stand at the windward and wear ppe.
Sampling after the scrub clean sampling apparatus.
Oil sampling tank should have sufficient liquidity
