Quality assurance of API 5CT Oil Tube

Because of API 5CT and ISO 9001 authorized, we have little claims from customers up to now. Just as showing in the quality control, Anson steel has professional testing laboratory and the ability for testing the samples. The experiment includes low and high temperature, impacting, rigidity, fatigue, fracture mechanism, falling weight, metallurgical, stress corrosion and compounds analysis etc. Therefore, choosing octg tubing from Anson steel is best choice with high quality and competitive prices!
