A106B Low Sulfur Phosphorus Pipe Fitting

Our factory main sulfur resistant pipe, elbow, sulfur resistance sulfur resistant pipe material, sulfur resistant steel tube, low phosphorus, sulfur and low sulfur phosphorus pipe, double pipe fittings, double resistance of steel pipe, double pipe resistance, low sulphur phosphorous tee, low sulphur phosphorous steel, corrosion resistant pipe fittings, resistance to acid tube parts, NACE, # 20 - H2S, L245NS, L360NS, L360QS, A106BNS, HTC (hydrogen induced cracking corrosion experiment), SSC (sulfide stress corrosion), etc.

SCC test, general also called SSCC mainly h2s stress corrosion test, general use on the oil pipeline and pressure vessel, usually for petrochemical products, generally there are American standard gb, customers usually time to do the test time is mainly considering, because the hydrogen sulfide corrosion SSC test cycle compared to 30 days for a long time, plus sample preparation needs about 35 days to finish the test, such as the HTC test cycle short, generally a week more can the results!

Solve the hydrogen sulfide corrosion resistant tube completely rely on imports, meet the needs of domestic oil and gas fields against hydrogen sulfide corrosion of steel tube, my company after years of hydrogen sulfide corrosion resistance research, on the basis of the domestic iron and steel enterprise development of low carbon, low phosphorus, sulfur, refine the grain size of hydrogen sulfide resistant pipeline steel, wire flux matching test, optimize welding process, molding process control, residual stress could satisfy the requirement of domestic oil and gas transportation developed L360MB (X52) hydrogen sulfide corrosion resistance of spiral submerged arc welding pipe, changed the gathering line, relying on domestic seamless steel tube or imported steel pipe, Filled the domestic gap in this field.

Sulfur resistant pipe fittings according to the NACE TM0177 (metal resistance to sulfide stress cracking in h2s environment and laboratory tests of stress corrosion cracking, and NACE MR0175 (oilfield equipment sulfide stress corrosion cracking and stress corrosion cracking resistance of metal materials) of international standards, the HTC (hydrogen induced cracking)/SWC ladder (cracking) test and SSC (sulfide stress cracking test, the results of the resistance to sulfur resistance to hydrogen accreditation. And high sulphur, high in the world of chlorine ion in the project, our company produces the high sulfur resistance to hydrogen pipe is suitable for the hydrogen sulfide content of 300 grams per cubic meters or more, 260 grams per liter or higher chloride ion content and a carbon dioxide 300 grams per cubic meters) or medium environment of acid wet natural gas and oil, and safe operation in the environment has been more than 15 years.
