TT Series Oil Well Pipe
H2S anti-corrosion oil well pipe
TT series H2S anti-corrosion oil well pipe adopted improved Cr-Mo steel. By increasing the purity of steel, spheroidizing the inclusions and controlling of the precise heat treatment, the material have excellent performance on sulfide stress cracking (SSC) resistance.
CO2 anti-corrosion oil well pipe
After research cooperating with Xinxing Ductile Iron Pipes Co., Ltd, our company has also made a great breakthrough in the development of high alloy anti-corrosion oil well pipe which consists of 9Cr, 13Cr, super 13Cr etc. Our company can bulk supply and our products have been exported to foreign countries.
High alloy content oil well pipe
Our company developed the TT series alloy oil pipes with great H2S-CO2-Cl corrosion resistance. These pipes have high alloy content, such as Cr, Ni, Mo etc, they have good comprehensive properties in high temperature and high corrosive envirnment.
High collapsing resistance casing
TT series high collapsing resistance casing, which is used in the conditions of salt rock bed, mudstone, high pressure injection well, high pressure stratum or unusual stratum stress oil & gas well, is developed by TTGM independently. After heat treatment, the mechanical property of HFW pipe can equal to N80Q, L80, P110, Q125, the dimension, uniformity of wall thickness is more accurate than seamless pipe, the collapsing resistance property is better than API standard pipe for more than 20%.
High strength oil well pipe
TT series high strength oil well pipe always used in the oil well which has special condition, such as evaporite bed, mudstone and sand production. The high strength oil well pipe which is non-API standard has obviously advantage in inhomogeneous loading condition, it can bear more inhomogeneous loading.
Heavy oil thermal production pipe
TT series heavy oil thermal production well pipe has great connection intensity, thermal deformation resistance and reliable sealing performance. The pipe body use Cr-Mo steel which has high thermal stability and collapsing strength; the premium connection is advanced in tensile strength, thermal deformation resistance and tightness. These advantages make sure steam injection can be operated for more than six times and increase the life span for more than 1 time.
Economy oil well pipe
TT50 series casing is the new type of non-API product which is developed by TTGM independently. The mechanical property can reach to the J55 steel grade casing. TT50 series casing can not only satisfied with the requirements by oilfield, but also reduce the cost in well drilling and increase the technical level, economic efficiency and competitiveness.
