CIP System for Milk Industry In milk production, the clean-in-place (CIP) system is essential, ensuring that equipment and pipelines are thoroughly cleaned between production batches to prevent contamination and microbial growth. Specifically, the CIP system is responsible for cleaning and disinfecting the milk transport line, storage tanks, pumps, and valves at the end of each production batch. It operates through …

The salt spray test for stainless steel tubes is a common accelerated corrosion test used to evaluate the corrosion resistance of stainless steel materials. This test mainly examines the performance of the protective surface layer of stainless steel tubes when exposed to a salt-containing environment. 1. Purpose of the Test The salt spray test simulates the corrosion conditions found in …

A maleic anhydride reactor is a specialized chemical reactor used to produce maleic anhydride (MA), typically through the partial oxidation of hydrocarbons such as n-butane or benzene. The reactor operates at high temperatures, often using vanadium-phosphorus oxide (VPO) catalysts to facilitate the oxidation process. Heat exchangers are incorporated to manage the heat released during the exothermic reaction, ensuring temperature control. …

Hydraulic tube expansion in heat exchangers is a method where tubes are expanded and sealed into a tubesheet by applying hydraulic pressure. This process can be divided into two main techniques: Bladder/Mandrel System: A clean and controlled method where a mandrel expands the tube without getting it wet. It is precise and efficient for thick tubesheets, as it completes the …

Heat exchanger tubes made in accordance with ASTM A213 are seamless low alloy steel (Cr-Mo alloy steel) or austenitic stainless steel tubes used for heat transferring in high-temperature and corrosive applications. These tubes are known for their excellent mechanical properties, including strength and resistance to oxidation and corrosion in demanding environments. In a heat exchanger, the tube sheet is a …

Boiler tube plugging refers to the process of sealing off a damaged or leaking tube to prevent further leakage or malfunction without needing to immediately replace the tube. The plugging operation is done by inserting and expanding specially designed plugs made from materials like steel or copper into both ends of the boiler tube. This technique allows the boiler to …

In oil extraction, wellhead pressure monitoring is critical. Instrument tubing connects the pressure sensors in the oil well to ground-level control devices, measuring wellhead pressure and helping operators adjust production rates to prevent blowouts or pressure loss. The material used for instrument tubing in oil well pressure monitoring typically needs to withstand high pressure, corrosion, and maintain high strength, as …

UNS C12200 is a commercially pure copper that is phosphorus deoxidized, with high residual phosphorus. It is also known as DHP copper. It is widely used for the manufacture of seamless copper water tubes in accordance with ASTM B88. The UNS C12200 seamless copper tubes are mainly intended for general pluming and the conveyance of other similar fluids. They are …

ASTM B88 UNS C12200 copper tubes are seamless copper water tubes made from copper alloy UNS C12200, which is a commercially pure copper that has been deoxidized with phosphorus, leaving a relatively high residual phosphorus content. It is not susceptible to hydrogen embrittlement, but is of relatively low electrical conductivity due to the amount of phosphorus present. UNS C12200 is …

ASTM A688 welded stainless steel tubes are usually furnished in the form of U tubes for application in tubular feedwater heaters. According to the supplementary requirement S1, each welded tube in finished condition prior to bending, shall be tested by passing it through an electric nondestructive tester capable of detecting defects on the entire cross section of the tube. This …

ASTM A249 welded stainless steel tubes are widely used in various industries working as heat exchanger, boiler, superheater, and condenser tubes. Compared to the seamless tubing, these welded stainless steel tubes offer several significant advantages: Cost Effective Manufacture The manufacturing process for ASTM A249 welded stainless steel tubes is more efficient and less costly compared to seamless tubes made to …
