Surface treatment: steel tube primary color, polishing, electroplating, sanitation grade, according to different customer requirements can be used in different surface treatment; Main application: Core supplement is a kind of spare parts, widely used in large domestic power station supporting projects, sea water, steam, cold water, hot water, oxygen, drinking water, refrigeration, oil, gas, medical gas sewage treatment projects, municipal engineering, chemical engineering, oil refining, metallurgy, fertilizer, paper, medicine and other industries. Connection mode: the core is one inner wire and one outer wire, which has socket connection and thread connection according to the situation. Different connection modes can be adopted according to different customer requirements.
