Fiberglass reinforced composite tubing
Product Description:
The fiberglass reinforced composite pipe has a three layer structure and is compounded through a special process. The air chamber is made of modified PVC with corrosion-proof, heat-resistant, anti-friction and airtight characteristics. Thermoset fiberglass with high strength and good stiffness is wound and cured as an intermediate layer. The outer plastic coating is extruded to resist the effects of aging and impact. Threaded metal fittings are attached at both ends. The optional foam jacket can be fitted under the outer jacket as an insulation measure. The pipe combines the benefits of thermoplastic and thermoset materials and is used as an alternative option to replace steel pipe or partially replace stainless steel pipe for the transmission of normal and corrosive media. It is now widely used in the petroleum, chemical, engineering, water supply and gas industries.
Benefits:
1. Excellent corrosion resistance and longer service life;
2. Low thermal conductivity coefficient and superior thermal insulation;
3. Smooth inner surface with small fluid drag force;
4. Oxygen index lower than 35, resulting in superior fire resistance;
5. Light weight, high tensile strength, easy transportation, installation and maintenance and good overall efficiency.

High pressure FRP pipe
Product Description:
The high surface FRP pipe adopts standardized long screw connection with 5B external upsetting which improves the sealing property with wear-resistant combined thread. The advantage is that the installation is so fast and convenient that it prolongs the service life. The downhole FRP tubing is highly efficient and super-reinforced, which is controlled for precision bending by computer. Advanced successive filament winding composition ensures the axial modulus and tensile strength with downhole operation. The maximum operating pressure of surface high pressure FRP tubing is 40 MPa, while downhole high pressure FRP tubing is 27 Mpa. The maximum working temperature is 82 ℃ with anhydride petrified epoxy-FRP , 100 ℃ with petrified aromatic amine. It can be at 120 ℃ under long-term work for high surface FRP pipes made of special heat-resistant epoxy resin system. The products' maximum working temperature of 149 ℃ has been made to meet some special application conditions which are in accordance with 15HR specification.
Main benefit
1. Low weight, approximately 1/4 steel stock;
2. Quick and easy installation in any weather without bonds;
3. Inner wall is smooth with excellent flow characteristics;
4. Excellent corrosion resistance and extremely long service life;
5. Low installation cost;
6. Low paraffin accumulation and deposition.

Special coating for heavy oil thermal recovery
Product Description:
This special type of liner is a completely new and self-developed patent product as a pipeline for heavy oil thermal recovery applications. The pipe body is made of Cr-Mo steel. The high thermal stability and collapse resistance characteristics of such material lead to better field performance, such as high connection strength, good thermal distortion resistance and reliable gas tightness. It can survive more than 6 steam injection cycles, which doubles the life of conventional casing in thermal recovery wells. This product proves to be a better solution for the high casing damage rate that existed in thermal recovery applications.

H2S corrosion-resistant oil pipes
Product Description:
At present, there are 1/3 of oil and gas wells containing H2S gas worldwide. In China, there are several oil fields (such as Sinkiang, Szechwan) containing H2S gas. H2S gas can cause stress corrosion cracking of casings and pipelines, which can lead to large losses. We developed SL H2S corrosion resistant oil pipes by partnering with foreign companies to solve the above problem. The test showed that this type of casing can be used in wells with 8% H2S gas content and could solve the corrosion cracking well.
Product features:
1.Low alloy pipe material, low P, S content;
2.Grain size > level 7, evenness and thinness;
3. Apply premium SL thread connection, good strength and reliable sealing;
4.Excellent H2S corrosion resistance, applied by medium/deep wells containing H2S gas.
