Shaanxi Province recently carried out a major price inspection on gasoline, diesel and liquefied gas after adjustments were made to refined oil prices. The price department issued a report on the issue and mobilized all sectors of society to participate in the supervision.
The inspection focuses on whether the refined oil production enterprises implement the state-set ex-factory price and floating range, and whether the ex-factory price of liquefied gas complies with the state regulations; whether the refined oil retail enterprise implements the national benchmark retail price and floating range; whether the refined oil sales enterprise exists In advance price adjustment or price increase (charge) behavior; sales of refined oil shortage quantity, lifted price, disguised price increase price illegal behavior; take advantage of refined oil price adjustment machine lift prices and fabricated, disseminate false information, drive up prices Acts; behaviors that are not priced as specified.

Brazed Plate Heat Exchanger

Brazed heat exchangers corrugated plates create multiple flow channels, maximizing the heat transfer surface area within a small footprint. This makes them ideal for applications where space is limited.

Brazed heat exchanger (BPHE) is a type of compact heat exchanger that consists of corrugated metal plates that are brazed together to form a single unit. The brazing process involves melting a filler material, tipically copper-based alloy (
Stainless or Nickle are available) between the plates to create a strong and leak-proof joint.
The main advantages of brazed heat exchangers include their high heat transfer efficiency, compact size, and reliability.The basic flow principle in a brazed plate heat exchanger is parallel to achieve the most efficient heat transfer process.In a single pass design, all connections are located on one side of the heat exchanger, making installation very easy.

The flow principle of a brazed heat exchanger is based on the counter-current flow configuration, where the two fluids involved in the heat transfer process flow in opposite directions. e.g the picture A and B
