Mechanical & Metallurgical Composite Pipes - Corrosion Solutions for the Chemical Industry<\/h3>\n
\n

In petrochemical refineries, chemical plants, fine chemical facilities and storage & transportation systems, process media such as hydrogen sulfide (H\u2082S), carbon dioxide (CO\u2082), chloride ions, acid-base media, sulfides and high-temperature oil and gas will cause severe corrosion, erosion and material failure to the pipeline system. Traditional carbon steel pipelines are prone to leakage, short service life and frequent maintenance, which seriously affect production safety, equipment continuity and economic benefits.
Jiangsu Zhongxin Pipe Sci-tech Co., Ltd. provides customized corrosion-resistant alloy composite pipes, lined pipes and surfacing pipes solutions for the petrochemical industry. Our products can effectively resist high-temperature, high-pressure and strong corrosion working conditions, ensuring the long-term safe and stable operation of petrochemical process pipelines.<\/p>\n\n\n\n

Core Advantages<\/strong><\/p>\n\n\n\n


Excellent Corrosion and Erosion Resistance<\/strong>
Adopting high-grade alloys such as 2205\/2507 duplex stainless steel, 625\/825 nickel-based alloy, 316L and 904L, it can effectively resist H\u2082S, CO\u2082, chloride ion stress corrosion, acid-base corrosion and high-temperature erosion.<\/p>\n\n\n\n


Adaptability to High Temperature and High Pressure<\/strong>
Suitable for high-temperature and high-pressure working conditions of petrochemical processes, with stable mechanical properties and safe and reliable structure.<\/p>\n\n\n\n


Reliable Metallurgical Bonding Strength<\/strong>
Through automatic surfacing technology, the alloy layer and the base pipe form a firm metallurgical bond, eliminating delamination, bubbling and interface corrosion.<\/p>\n\n\n\n


Extend Service Life & Reduce Comprehensive Costs<\/strong>
Greatly reduce the frequency of pipeline replacement, maintenance and unplanned shutdowns, effectively lowering the full-life cycle cost of petrochemical projects.<\/p>\n\n\n\n


Strict Quality Inspection & Compliance with International Standards<\/strong>
Full-process non-destructive testing, hydrostatic testing and performance inspection are carried out. The products comply with petrochemical industry standards such as GB\/T 31940, API 5L, API 5LC, API 5LD, DNV-ST-F101, NACE MR0175\/ISO 15156 and ASME.<\/p>\n\n\n\n
