The welded spiral heat exchanger is built by rolling two long metal plates around the center core to form two concentric spiral flow passes, one for each fluid. The edges of the plate are welded shut so that each fluid stays within its own passage and there is no flow bypassing or intermixing. The width and spacing of the channel plate (the gap between plates) are designed for specified operation, maximum heat transfer, and ease of access. These heat exchangers are built to deal with the toughest challenges of heat transfer. Whether it's frequent fouling of dirty media, or restriction of pressure drop and floor space, it's the ultimate approach for liquid-to-liquid and two-phase activities. Due to these characteristics, welded spiral heat exchangers are used in various industries such as chemical, food & beverage, petrochemical, HVAC & refrigeration, power generation, pulp & paper, wastewater and other industries.
The market for welded spiral heat exchangers is driven by growing preference for welded spiral heat exchanger in petrochemical industry, growing industrial development in the Asia Pacific region and growing concern for sustainable energy development and intensive demand for energy efficiency is augmenting the growth of the heat exchanger. Welded spiral heat exchangers deliver high thermal efficiency in comparison to shell & tube heat exchangers. They also have a minimal footprint and are easy to access during maintenance and repair. The benefits provided by the welded spiral type of heat exchangers are expected to boost their demand for dangerous and aggressive fluids in the petrochemical industries, as leakage is essentially excluded due to welded channel construction.
Covid19, drastically affects the world supply chain and industrial sector growth. At the initial stages of the pandemic, the world experienced, ‘supply shocks’. China who plays a major role in the world’s supply chain was severely affected. There were disruptions to the availability of goods supplied from China. Supply of both finished and unfinished goods reduced. Day by day as the situation worsened, quarantines, social distance practices were imposed and nations begun instituting lockdowns. Following this the supply chains experienced demand shocks. The shutdown of economic activities affected all the sectors. Manufacturing and mining industry’s sluggish growth in turn affected the welded spiral heat exchangers market. Moreover, the steel, aluminum, copper manufacturing industries experienced a pullback due to sluggish demand.
The report analyses the welded spiral heat exchangers market based on material, flow type, industry, and geography
Based on the material, the market is divided into steel and non-steel. Among these, the steel segment holds the largest market share in the forecast period owing to its beneficial properties like high corrosion resistance at a wide range of pH levels, lightweight, high thermal conductivity, and high performance than other materials.
Welded spiral heat exchangers are usually made of steel, which provides high heat thermal conductivity. The material enables the system to operate at a lower temperature difference and reduce the weight of the equipment. The demand for steel-based welded spiral heat exchangers is increasing from various end-use industries such as chemical, food & beverage, petrochemical, HVAC & refrigeration, power generation, pulp & paper, wastewater industry, and others.
There are two types of flow are countercurrent flow and co-current flow. Among these, the counter-current segment is likely to expand at a fast rate over the projected period, as the counter-current flow allows a diverse range of fluid temperatures to be exchanged and is highly effective than the other flow types. Countercurrent exchange systems are commonly applied in industry and are frequently observed in nature. For instance, a heat exchanger can be arranged in a countercurrent configuration to increase the overall heat transfer. The same principle is also useful for optimizing the transfer of chemical species from one flow to another.
The major end-use industries of global welded spiral heat exchangers are chemical, food & beverages, HVAC & refrigeration, petrochemicals, power generation, pulp & paper, wastewater industry and others. Besides, mounting demand from the chemical industry, technological innovation, and increasing focus on refining efficiency standards are further expected to drive the growth of the market over the forecast period. Moreover, growing chemical industry in the region is likely to result in increased product demand over the forecast period. Growing refinery capacities and the establishment of new chemical plants in the country are further expected to drive the growth of the market over the forecast period.
