Application
Stainless steel has outstanding corrosion-resistant, wear-resistant, and heat-resistant properties with exceptional strength and toughness. Stainless steel casting parts & components are critical for many demanding industrial applications. These parts are widely used in the machinery and facilities in various industries, such as waste water treatment, chemical & petrochemical, food & pharmaceutical , marine & offshore, pump & valve, pulp and paper making, energy & nuclear etc.
Separation
Separation between solid phase and liquid phase are widely required across a wide range of industries. The separation is mainly achieved through a decanter centrifuge. The decanter centrifuge can separate solid particles from liquid suspension, or separate different liquid phases.
A lot of suspensions, such as waste water, oil sludge, mining mud, palm oil, are corrosive and abrasive. Thus A strong material with excellent corrosion resistant and wear resistant properties are required for the critical parts of a decanter centrifuge. Duplex stainless steel 2304 or 2205, and Austenitic stainless steel 304 or 316 are chosen, due to its superior properties and cost effectiveness, for the bowls and scrolls of a decanter centrifuge.
Pump & Valve
Many Pumps and valves are installed to transport corrosive liquids or gases, especially sea water, waster water, chemicals, oils, etc. Centrifugal cast or sand cast stainless steel valves and volutes are tasked to handle the challenge.
Critical parts of pumps and valves, such as Valve body and core, pump volute, compressor volute, pump impeller, etc. are mainly made of different grades of stainless steel to deal with corrosive liquids and air. The performance of these parts are long been proven.
Pulper & Paper
In the field of paper making industry, the fibre solution have corrosive effects on the equipment. The corrosion media of the bleaching equipment are mainly Cl -, H+in the chlorination section, as well as oxidants Cl2 and ClO2. There is severe corrosion on the top of the chlorination tower or the pulp washer, and it cannot be used with 316L stainless steel.
2101, 2304, and 2205 duplex stainless steels are perfect for these conditions that can effectively solve the anti-corrosion problem. The rotors or impellers of puler machine are generally made with duplex stainless steel by static casting to achieve the best performance.
Environment
Decanter centrifuges, pumps, pipes and valves are widely used in the environment industry. Waste water, industrial liquid waste are generally corrosive. Equipment designed for these applications should be corrosion resistant and wear resistant.
Centrifugal casting or sand casting stainless steel parts are chosen to manufacture the equipment used in the demanding conditions. Duplex stainless steel decanter bowls, stainless steel pump volutes and impellers, valve body and cores are the main applications.
Hydro-power
In the hydro-power section, the impeller, volute and casing should be corrosion resistant and wear resistant with strength and toughness. These big parts are mainly made of stainless steel by static casting.
Marine & Offshore
Sea water is quite corrosive. The equipment used in marine & offshore must be able to handle the challenge. Stainless steel casting parts are used in various conditions, such as pump volute and impellers, valve and bushings, etc.
Oil & Gas
Valves & pipes, oil recovery decanter centrifuges, solid control systems are widely used in the oil & gas industry. Centrifugal casting parts and sand casting parts are mainly used in these equipment and facilities.
Chemical & Petrochemical
Many chemical fluids and gases are corrosive. Equipment used in these applications must be able to deal with these challenges. Stainless steel Pumps, valves and pipes, cylinders, etc. are easily found in the Chemical & Petrochemical industry. Many of the parts of the equipment are made by centrifugal casting or sand casting to ensure the best performance.
