Butt-welded Fittings

  • Monel 400 Fittings

    Monel 400 Fittings

    Monel alloy has comprehensive properties of strong toughness and corrosion resistance, and is widely used in chemical and other industries. For example, for the manufacture of heaters, heat exchangers, evaporators, distillation kettles, distillation towers, fatty acid treatment condensers, processing Rosin Pavilion acid equipment, chemical pumps, etc.

    Because the Monel alloy also has high strength and good oxidation resistance at high temperature, it can also be used in heat treatment industry to manufacture all kinds of structural parts. In the nuclear power industry, the alloy has good corrosion resistance to high temperature and high pressure water, so it is also an important structural material for light water reactor nuclear power plant. The products are plate, rod, wire, strip and pipe.

  • S31803 Duplex Fittings

    S31803 Duplex Fittings

    S31803 duplex fittings have good welding performance, compared with ferrite stainless steel and austenitic stainless steel fittings. it is not like the welding heat-affected zone of ferrite stainless steel, and the plasticity and toughness are greatly reduced due to severe grain coarsening. Nor is it as sensitive to welding thermal cracks as austenitic stainless steel.

    Due to its special advantages, S31803 duplex fittings have been widely used in petrochemical equipment, seawater and wastewater treatment equipment, oil and gas pipelines, paper-making machinery and other industrial fields. In recent years, it has also been used in the field of bridge load-bearing structure.

    It has a good prospect of development. Duplex stainless steel is composed of half ferrite phase and austenite phase in the quenched microstructure, and the content of the minimum phase may be up to 30%.

  • 180 Degree Return Bends

    180 Degree Return Bends

    180 degree return bends require very high demand for production process. From raw materials, manufacturing technology, to finished products.

    Do well products trace-ability is one of the key points for 180 degree return bends. We do PMI test from raw materials to final products, so, the labeled transplantation is very important.

    Nondestructive examination (NDE) need carry out on each piece of the 180 degree steel elbows. Depends on the materials, we need do Magnetic particle test, Penetration test, Ultrasonic test, Radio graphic test, and any other as customers' requirements.
