Gasketed Plate Heat Exchangers: Consist of multiple plates with gaskets to seal the edges and create flow channels. Easy to disassemble for cleaning, maintenance, or capacity adjustment. Suitable for moderate temperature and pressure applications. Brazed Plate Heat Exchangers: Plates are brazed together using copper or nickel, creating a compact and leak-proof unit. Ideal for high-pressure and high-temperature applications. Commonly used in refrigeration and HVAC systems. Welded Plate Heat Exchangers: Plates are welded together, eliminating the need for gaskets. Suitable for corrosive fluids, high temperatures, or high pressures. Used in chemical, oil, and gas industries. Semi-Welded Plate Heat Exchangers: Combines welded and gasketed plates. One fluid path is welded (for aggressive fluids), and the other is gasketed (for less aggressive fluids). Ideal for applications requiring a balance between durability and maintenance flexibility. Fully Welded Plate Heat Exchangers: All plates are welded together, providing a robust and leak-proof design. Suitable for extreme conditions, such as high temperatures, pressures, or corrosive environments. Single-Pass Plate Heat Exchangers: Fluids pass through the heat exchanger once. Simple design with lower pressure drop. Multi-Pass Plate Heat Exchangers: Fluids pass through the heat exchanger multiple times. Increases heat transfer efficiency but may result in higher pressure drop. HVAC Plate Heat Exchangers: Used in heating, ventilation, and air conditioning systems. Efficient for heat recovery, chillers, and heat pumps. Industrial Plate Heat Exchangers: Designed for industrial processes such as chemical, food, and pharmaceutical industries. Handles high temperatures, pressures, and corrosive fluids. Refrigeration Plate Heat Exchangers: Used in refrigeration systems for evaporators or condensers. Compact and efficient for low-temperature applications. District Energy Plate Heat Exchangers: Connects to district heating or cooling networks. High-capacity and energy-efficient. Stainless Steel Plates: Corrosion-resistant and durable. Suitable for most applications, including food and beverage industries. Titanium Plates: Highly resistant to corrosion, especially in seawater or chloride environments. Used in marine or chemical industries. Nickel Plates: Resistant to high temperatures and corrosive fluids. Ideal for chemical processing or oil and gas industries. plate heat exchanger,plate type heat exchanger,plate exchanger,plate and frame heat exchanger,phe heat exchanger,plate heat exchanger gasket,industrial heat exchanger,thermal heat exchanger,heat exchanger hvac,high efficiency heat exchanger Siping Juyuan Hanyang Plate Heat Exchanger Co., Ltd , https://www.tj-heatexchange.com1. Based on Construction and Design

After a slight increase in epichlorohydrin prices in September, the market remained relatively stable. By the end of the month, domestic prices closed at Dayang, reflecting a cautious outlook. However, on October 8th, Qilu Petrochemical and Tianjin Chemical both raised their prices to 18,000 yuan per ton, triggering a wave of price hikes across the industry. This round of increases exceeded 2,000 yuan, marking a significant shift in market sentiment. Currently, the market is trading above 18,000 yuan, with contract customers paying 18,000 yuan, while spot buyers are accepting around 18,500 yuan. The epichlorohydrin market has finally turned around from its long-term decline, with sharp price gains and an overall improvement in market mood.
The price surge was initially driven by a drop in domestic supply, which fell short of initial expectations. It was anticipated that supply would significantly increase in October, leading to a lack of confidence among market participants and reluctance to push prices higher. However, in October, several manufacturers faced operational issues. Shandong Bohui Chemical’s second-phase 80,000-ton plant was temporarily shut down, Jiangsu Yangnong Chemical underwent maintenance, and Tianjin Chemical scheduled repairs for this month. Qilu Petrochemical also planned to halt operations on the 20th for overhauls. Meanwhile, Baling Petrochemicals reduced foreign sales due to rising domestic demand. These disruptions led to a supply shortage, intensifying the imbalance between supply and demand. As a result, the transaction atmosphere improved, with more attention on pricing and fewer low-cost sources available.
In addition, downstream demand started to pick up. Although the overall epoxy market remained stable, there were signs of increased demand. Some previously parked facilities began resuming operations, and the overall operating rate rose. Solid one-step resin prices reached around 23,000 yuan, while liquid resin prices ranged from 27,000 to 28,500 yuan. In the early stages, weak demand for epoxy resins had kept production levels low, resulting in lower supply and better market conditions. However, as epichlorohydrin prices surged, buying enthusiasm increased, tightening supply and making procurement more challenging. This further fueled the active trading environment.
Moreover, changes in import and export dynamics also influenced domestic prices. In August, China exported 1,003 tons of epichlorohydrin and imported 6,676 tons of chloropropane. Export volumes jumped by 161% compared to the previous month, while imports dropped by 63 tons. Russian supply sources became tighter, and October imports are expected to remain limited, adding pressure to the domestic market. Import prices for October were concentrated between 1,950 and 2,000 U.S. dollars (CFR).
In the short term, the sharp rise in prices has marked a new chapter for the epichlorohydrin market after years of decline. With supply shortages and unstable production schedules, traders have been forced to sell reluctantly. Domestic supply remains tight, and foreign trade associations are expected to raise their quotes in the second half of the month. The potential for further price increases is strong, but from an operational perspective, pushing prices higher may not be sustainable in the long run. Market participants will need to closely monitor the situation moving forward.
Plate Heat Exchangers (PHEs)Â are compact, efficient devices used to transfer heat between two fluids without mixing them. They are widely used in industries such as HVAC, chemical processing, food and beverage, and power generation. Below is a detailed classification of Plate Heat Exchangers based on their design, construction, and application:
