  • Duplex stainless pipe
    Alloy 2205 (UNS S32305/ S31803) is a 22% chromium, 3% molybdenum, 5-6% nickel, nitrogen alloyed duplex stainless steel pipe with high general, localized, and stress corrosion resistance properties in addition to high strength and excellent impact toughness.

    Alloy 2205 provides pitting and crevice corrosion resistance superior to 316L or 317L austenitic stainless steel tube in almost all corrosive media. It also has high corrosion and erosion fatigue properties as well as lower thermal expansion and higher thermal conductivity than austenitic.

    Standard: ASTM/ ASME A789/ SA789, A790/ SA790
    Steel Grade: UNS S32750, S31803, S32760 etc.
    Applications:
    General service, fluid transportation, pressure, high and low temperature, structural, heat exchanger, oil and gas service, ornamental, chemical and fertile

    Duplex stainless steel 2205 has below
  • Ceramic Tile Lined Steel Pipes and Elbows
    Ceramic Tile Lined Steel Pipes and Elbows have very uniform coating of specially formulated ceramic material that is affixed to the inner of the pipe and gives a very smooth surface. Ceramics with very low friction factor at low impingement angles decreases the abrasion of materials maximally. Its low density makes it easy to carry and install. Furthermore, its diamond-like hardness, fine grain structure and superior mechanical strength are the unique features that make it a wide range of demanding applications, such as coal preparation, power generation, iron and steelmaking, cement, asphalt, dredging, mining and mineral processing, oil and gas drilling.

    Metals have good ductility but poor resistance to abrasion - which means that abrasion prevention is required when metal pipes are used in high-temperature fluid catalyst service. On the other hand, ceramics possess great hardness and abrasion resistance, but they are brittle. Metal Ceramic double pipe is a hybrid pipe using metal as an outer pipe and a ceramic material for inner pipe segments, applied together to utilize the two materials' advantages. Hence excellent wear-resistance and good corrosion resistance of the ceramics and high strength and toughness of metal can be well combined to get a comprehensive advantage of wear-resistance, corrosion-resistance and anti-scaling. They are suitable for applications in heavy wear working conditions.

    Ceramics are among the hardest materials available and provide ultimate wear resistance in piping. In high wear applications, ceramic lined pipes have been demonstrated to be cost-effective by increasing service life and reducing maintenance costs. Sunny Steel supply ceramic lined abrasion resistant steel pipes to your custom dimensions and budget. Our ceramic linings are the highest quality materials available to ensure that we provide the most cost-effective solutions for our clients.

    The Ceramic Tiles could protect Industrial Components against abrasion, impact wear and high temperature of above 1000°C. Standard Flat Tiles of Square & Rectangular Shape having thickness of 6 to 50 mm, with or without central hole are available.

    Materials: seamless mild steel pipe plus 95% alumina ceramics for liner
    Designed pressure: >= 0.35Mpa
    Normal operation velocity: 20-35m/ s
    Normal operation temperature: -50-800
    Running medium: mixture of air and powder
    Size of the pipe: the inner diameter is between 1 to 120 or even lager
  • Pipe elbows
    Steel elbow is used to be installed between two lengths of pipe or tube allowing a change of direction, usually these carbon steel elbows distinguished by connection ends, The ends may be machined for butt welding , threaded , or socketed , so the carbon steel elbows are consist of butt weld, thread elbow socket elbow and other series.the material is selected according to the application use such as high temperature use, sanitary fitting, regular industrial use etc.

  • Blind Flanges, BL Flange, BLRF
    The blind flange is used to close ends of piping systems. It is a kind of round plate with no center hold but with all the proper bolt holes. This blind flange is available in various sizes and materials and is used to provide positive closer on the ends of pipes, valves or equipment nozzles. This flange helps in easy access to a line once it has been sealed. The blind flange is sometimes custom made or machined to accept a nominal sized pipe to which reduction is being made. This reduction can be a threaded reduction or welded reduction.

  • Ceramic Lined Elbows and Bends
    Wear Resistant Pipe and Elbow for Pneumatic Conveying
    Tubes and bends in pneumatic conveying lines are suffering more or less abrasion. SunnySteel's ceramic lined pipes resists abrasion and avoids product attrition.It reduces considerabley degradation of conveyed material and avoids formation of angel hair through its patented deflection chamber.The compact design reduces cost of pipe support and installation. It is automatically self-purging with little pressure drop.

    Ceramic Lined Elbows and Bends could be also applied in the parts of concrete pump owing to their advantages especially the low weight which helps to avoid the jam during the transport of concrete.

    Features of Alumina Ceramic:
    Alumina is a cost effective and widely used material in the family of engineered ceramics. Alumina ceramics have been developed and optimized for maximum wear resistance and corrosion resistance.
    A high density, diamond like hardness, fine grain structure and superior mechanical strength are the unique properties that make it the material of choice for a wide range of demanding applications.Ceramic has uses similar to Cast Basalt but it has greater resistance to wear in high velocity applications and impact resistance in extreme dynamic systems .

    Due to the above properties of Alumina Ceramic, Ceramic Lined Pipe Elbows have the following superiorities.

    Low friction factor of Ceramic at low impingement angles decreases the abrasion of materials maximally.
    Ceramic-lined composite steel pipe can take place of expensive stainless steel, nickel, cast stone or alloy pipes.
    And extended service life can also reduce maintenance cost.
    Preventing operation cease caused by frequent replacement of pipes and elbows .
    Excellent thermal resistance and abrasion resistance by ceramic material processing.
    Distinguished adhesive strength by high-temperature bonding agent.
    10~20 times longer life span than products processed with SS, etc.
    No substance intermixed by abrasion during transportation.
    Low density makes the wear resistant pipe elbow easy to carry and install.
  • Bi Metal Clad Pipe, Bend
    1. Manufacturing Process of Bimetal Clad Pipe and Bend:
    Bimetal Clad Pipe and Bend are cast with mold vanishing vacuum suction casting cladding process. Outer of straight pipe is common steel pipe, cladding realized by forming high chromium lining via centrifugal forming technique. Outer of bend uses hot-bending bend and lining is cast with high-chromium cast iron. Bends and other profile sections can be cladded in whole and this process has changed the traditional practice to fabricate bend and other profile sections by drawing polyline without changing flow pattern of material inside piping, greatly reducing conveyance resistance of material.

    2. Advantages Compared with Traditional Wear Resistant
    Alloy Cast Iron, Alloy Cast Steel, General Clad Steel Pipe and Cast Stone Pipe:
