EPOXY RESIAN COAT ANTI-CORROSION TUBING
1. High mechanical strength, excellent tenacity.
2. the epoxy resin coat tightly adheres to the tubing body, so it can increase the reliability and prevent it from slough off and polluting the grand.
3. The coat is not poisonous and non-pollution,
4. Excellent physical and mechanical performance, and electric insulation.
5. Good heat resistance allows the continuous operation under the temperature of 150°C.
6. The smooth surface can prevent dirt from accumulating and increase the medium transportation ability.
7. Adopt special sealing technology, anticorrosive layer spread all over the end surface of tubing, inner and outer chamfer angle and coupling screw thread to insure the anticorrosive ability in fluid channel of tubing.
H2S CORROSION RESISTANCE PETROLEUM PIPES
At present, there are 1/3 oil and gas wells containing H2S gas all over the world. In china, there are several oil fields (such as Sinkiang, Szechwan) containing H2S gas. H2S gas can cause Stress Corrosion Cracking of casings and tubings, which can result in huge loss. We developed SL H2S Corrosion Resistance Petroleum Pipes associating with foreign companies in order to solve the hereinbefore problem. The test showed this casing type can be used in wells with content of 8% H2S gas and could well-solve corrosion cracking.
ANTI ABRASION TUBING
1. Increase productivity of your producing oil wells
2.Unbeatable corrosion and chemical protection in both producing and water injection/disposal wells
3.Reduced rod torques
4.Eliminate harmonics
5. Friction reductions
6.Increased BHP life
7.Less rod wear
HDPE Advantage
1.Abrasion resistant
2. Superior chemical and corrosion resistance
3.Very effective in used tubular
4.Mechanically bonded
5.Erosion resistant
6.Very tough, yet flexible
7.Non ionic bonding surface
HI PRESSURE FRP PIPE
Surface high FRP pipe adopts API 5B external upset standardized long screw connection which improves sealing property with wearproof combined thread.
The advantage is that installation is so rapid and convenient that extends life. Downhole FRP pipe is high efficient and super-strengthened which is controlled to twist accurately by computer. Advanced successive filament winding composition ensures axial modulus and resistance to tension with downhole operation.The max operation pressure of surface high pressure FRP Pipe is 40MPa while downhole high pressure FRP Pipe is 27Mpa.The max work temperature is 82 with anhydride petrified epoxy-FRP, 100 with aromatic amine petrified. It can be at 120 under long-term work for surface high FRP pipe made of special heat-resistant epoxy resin system. Maximum operating temperature of 149 products has been made in order to meet some special application conditions which is according to API 15HR specification. All of pipes win the trust of customers with high performance.
GAS TIGHT PREMIUN THREADS
The self-developed SL-110CQ gas-tight premium thread has passed the test and evaluation by Xi’an Tubular Goods Research Center of CNPC. It is superior in sealing performance, excellent in collapse and buckle resistance and convenient for make-and-break. The premium thread has been successfully applied on tubular goods and used in key domestic oilfields such as Daqing, Shengli and Zhongyuan etc.
CASING HEAD
Typography is the art and technique of arranging type to make written language legible, readable and appealing when displayed. The arrangement of type involves selecting typefaces, point size, line length, line-spacing (leading), letter-spacing (tracking), and adjusting the space within letters pairs (kerning).
