Our factory is mainly engaged in anti-sulfur pipe fittings, anti-sulfur elbow, anti-sulfur pipe, anti-sulfur steel pipe, low-sulfur phosphorus, low-sulfur phosphorus pipe, double-resistance pipe, double-resistance steel pipe, double-resistance pipe, low-sulfur phosphorus tee, low-sulfur Phosphorus steel pipe, corrosion-resistant fittings, acid-resistant fittings, NACE, 20 # -H2S, L245NS, L360NS, L360QS, A106BNS, HIC (hydrogen induced cracking corrosion test), SSC (sulfide stress corrosion), etc.

The scc test is also commonly referred to as the SSCC test. It is mainly used for hydrogen sulfide corrosion stress detection. It is generally used on petroleum pipelines or pressure vessels. It is mostly used for petrochemical products. There are generally American and national standards. Customers generally consider this test when they are doing it. It's time, because the SSC test cycle of hydrogen sulfide corrosion takes 30 days, and the sample preparation takes about 35 days to complete the test. The HIC test cycle is short, and the results can usually be produced in more than a week!

Solve the problem that the anti-hydrogen sulfide corrosion pipe is completely dependent on imports, and meet the domestic demand for anti-hydrogen sulfide steel pipes in oil and gas fields. Based on years of research on anti-hydrogen sulfide corrosion, our company uses low-carbon, ultra-low-phosphorus, Sulfur-refined grain-resistant hydrogen sulfide-resistant pipeline steel was subjected to welding wire flux matching tests to optimize the welding process. Residual stress was controlled through the forming process. A L360MB (X52) grade hydrogen sulfide corrosion-resistant spiral burial was developed to meet domestic oil and gas transportation requirements. Arc welded pipes have changed the situation of domestic gathering and transportation pipelines relying on seamless steel pipes or imported steel pipes, and filled the domestic gap in this field.

Sulfur-resistant fittings according to NACE TM0177 (laboratory test of metal against sulfide stress cracking and stress corrosion cracking in a hydrogen sulfide environment) and NACE MR0175 (metal material for anti-sulfide stress corrosion cracking and stress corrosion cracking of oilfield equipment) international standards Through HIC (hydrogen induced cracking) / SWC (step cracking) test and SSC (sulfide stress cracking) test, the results of sulfur and hydrogen resistance were qualified. And verified in the international high sulfur and high chloride ion projects, our company's high sulfur and hydrogen resistance pipe fittings are suitable for (hydrogen sulfide content ≥300 g / m3, chloride ion content ≥260 g / l And carbon dioxide content ≥300 g / m3) in acidic wet natural gas and crude oil media environment, and has been operating safely in this environment for more than 15 years.
