Weld Overlay Clad Steel Pipe
The weld overlay clad steel pipe adopts advanced automatic weld overlay technology to clad a layer of high-wear-resistant, corrosion-resistant and high-temperature-resistant alloy materials (such as nickel-based alloy 825, 625, duplex stainless steel, etc.) on the inner wall of the base pipe. By accurately controlling the cladding thickness and dilution rate, it achieves perfect integration of the base pipe and the surfacing layer, significantly improving the service life and safety performance of the pipe under extreme working conditions. The product is accurately adapted to designated high-end industries and widely used in heavy industrial fields such as oil and gas (offshore oil and gas platforms, downhole oil and gas transmission pipelines), chemical industry (supporting pipelines for high-end chemical reactors, transportation of corrosive media), marine engineering (seawater desalination, offshore platform pipe networks), and electric power (nuclear power plant cooling systems, high-temperature and high-pressure pipelines in power plants). It is the core solution to replace traditional lined pipes and integral alloy pipes.
Outstanding Core Advantages: Excellent high-temperature resistance, corrosion resistance and wear resistance, capable of withstanding high temperature and high pressure of hydrogenation units in refineries, corrosive media of nuclear power plant cooling systems, and complex environments of offshore oil and gas platforms; service life is 3-5 times longer than that of ordinary steel pipes. Adopting automatic surfacing production line, the welding layer is uniform, and the surfacing material and thickness can be customized according to extreme working conditions. Relying on the breakthrough of domestic alloy surfacing technology, it has much higher cost performance than imported products, helping the localization of high-end equipment and adapting to the harsh requirements of key engineering projects such as Sinopec, PetroChina and CNOOC.
Recommended Products
RecommendationsMetallurgically Composite Pipe Fittings
Metallurgical composite pipe fittings (also known as bimetallic metallurgical composite pipe fittings) are high-end pipeline accessories integrally formed by combining high-strength carbon steel/alloy steel base layer with high-performance corrosion-resistant alloy cladding through metallurgical bonding process (atomic-level molecular fusion). They integrate structural strength, corrosion resistance and economy, and are the core solution for high-temperature, high-pressure and strong corrosion working conditions.
Mechanically Lined Steel Pipe(MLP)
Adopting advanced mechanical spinning composite technology, the mechanical composite steel pipe closely bonds two complementary metal materials (usually carbon steel as the base pipe, and stainless steel, duplex steel, nickel-based alloy, titanium alloy, or Monel alloy as the inner liner) through elastic and plastic deformation. It requires no high-temperature fusion, featuring full-process green environmental protection and high energy efficiency. Strictly complying with international and industry standards such as API-5LD, DNV-ST-F101, SHELL DEP 31.40.20.32-Gen., ADNOC-AGES, GB/T31940, and CJ/T 192, the product combines the high strength and high pressure-bearing capacity of the outer base pipe with the corrosion resistance and wear resistance of the inner cladding, effectively solving the industry pain points of "insufficient strength" or "poor corrosion resistance" of single-material pipes.
Bimetal Composite Pipe: Corrosion Solution for Offshore Engineering Pipelines
Offshore engineering operations, including deep-sea oil and gas development, subsea pipeline transportation, and offshore platform piping systems, operate under extreme corrosive conditions. Pipes are continuously exposed to multiple corrosive agents—high-salinity seawater, concentrated chloride ions, dissolved oxygen, carbon dioxide (CO₂), hydrogen sulfide (H₂S), and marine microorganisms—compounded by deep-sea high pressure, temperature fluctuations, and wave impacts. These harsh environments often lead to premature pipeline corrosion failure, threatening the safe and stable operation of offshore projects, shortening service life, and even triggering catastrophic safety incidents and substantial economic losses.
Mechanical Composite Pipes: Pipeline Solutions for Municipal Water Supply, Heating and Gas Industries
Municipal water supply, heating and gas pipelines are the "lifeline" of urban infrastructure, directly affecting residents' quality of life and urban operation. For years, traditional pipelines in municipal networks have been plagued by corrosion, leakage, high maintenance costs and short service life—issues that severely compromise network safety and stability. Mechanical composite pipes, with mature composite technology and outstanding overall performance, precisely address these municipal pain points, delivering efficient, durable and cost-effective full-scenario solutions for municipal water supply, heating and gas pipelines. Balancing practicality and economy, they ensure the long-term, reliable operation of urban infrastructure.
