Anti-blocking agent SM-FD for petroleum pipe line is designed for anti-blocking of petroleum pipe line and improvement of the oil pumping efficiency with high efficiency and cost efficiency, especially for high viscosity and oil mixture of water. It also can prolong the cleaning cycle of the petroleum pipe line. Its production capacity is of several hundred thousand tons/year 
 
Properties:
Appearance:   pale yellow or yellow brown liquid
pH value:      7-8
Valid content:  50%
Surface tension: （25℃,0.1%-0.3% water solution, mN/m）≦30
oil-water interfacial tension: （25℃,0.1%-0.3%water solution, mN/m）10-2 ～10-3
 
Characteristic:
It features good resistance to high temperature and salt, low pollution, low damage and easy operation.
 
It can reduce and eliminate the adhesion of oil and improve the oil pumping efficiency with reduced oil-water interfacial tension to an ultra-low state of 10-2 ～10-3 mN/m.
 
Excellent emulsification: It can disperse and strip the oil from the petroleum pipe line via the shearing flow of water and oil phase to form O/W emulsion, and then anti-blocking can be realized by improving the mobility ratio of oil to water and sweep coefficient.
 
Use and dosage:
The dosage is determined according to the property of the oil.
