High temperature and high pressure corrosion test is a kind of metal crack in the high temperature and high pressure environment, which is related to the corrosion and tensile stress (residual and applied).
The laboratory professional to provide various types of corrosion test project:
1, SSC sulfide stress corrosion test: standard tensile test, four point bending test, bending test standard, the standard C ring test, standard double cantilever beam test, using standard NACE TM 0177-2005, GB/T4157-2006, ASTM G39-99, ISO 7539-2011, NACE MR0175, SYT0599
2, HIC anti hydrogen embrittlement cracking test: using standard NACE TM0284-2011, GB/T8650-2006 NACE, MR0175 SYT0599., if the sample exerts a force is SOHIC cracking test stress oriented hydrogen.
3, high temperature and high pressure corrosion test: normal temperature is less than or equal to 150 DEG C, the pressure is less than or equal to 3MP, other conditions can be negotiated according to customer requirements.
4, the uniform corrosion test: also called laboratory corrosion tests using standard JB/T7901-2001, GB/T25147-2010, temperature are less than 100, no pressure, time is less than 168h.
5, boiling magnesium chloride stress corrosion test: the standard YB/T5362-2006, GB/T17898-1999, G36-2006 ASTM, only do U type bending test, the consultation cycle is generally 168h to see if there is a crack. Part of the product for a long time does not appear cracks can also consult the test cycle.
6, simulation conditions of corrosion test: this test is not standard test, corrosion test conditions are determined.
7, intergranular corrosion test is mainly intergranular corrosion in stainless steel -GB/T4334-2008, ASTM A262-2010, nickel based alloy intergranular corrosion test -GB/T15260-1994. is sulfuric acid method, nitric acid, nitric acid and hydrofluoric acid, sulfuric acid copper sulfate, hydrochloric acid method etc..
8, ferric chloride pitting test: GB/T17897-1999, ASTM, G48-2009
9, pitting evaluation and inspection: ASTM, G46 GB/T18590-2001
10, salt spray test, neutral salt spray test, acid salt spray test, copper accelerated salt spray test, alkaline salt fog test, GB/T10125-2012, mainly to see the rust detection of rust grade (grade 0-10), more than 8 points of anti rust ability of rust
