lwil oliv ak gaz industies yo mande èl serye pou En, midstream ak pwosesis en. Nan konstriksyon an nan sa yo pwojè gwo-echèl, kondisyon sa yo k ap travay yo se divès ak konplèks, ki enplike yon gwo kantite medya ak materyèl yo. Gen anpil kondisyon espesyal pou bon jan kalite a nan èl yo ak lòt ekipman. DHDZ ofri èl satisfè egzijans yo fè pou rezistans nan SULFIDE estrès fann (SSC) nan enviroments pwosesis rafineri vèt, sa vle di, enviroments ki gen mouye SULFIDE idwojèn (H₂S).

The oil and gas industies demand reliable flanges for Upstream, Midstream and Downstream processes. In the construction of these large-scale projects, the working conditions are diverse and complex, involving a large number of media and materials. There are many special requirements for the quality of the flanges and other fittings. DHDZ offers flanges meeting the requirements for resistance to sulfide stress cracking (SSC) in sour refinery process enviroments, i.e., enviroments that contain wet hydrogen sulfide (H₂S).
