Several factors drive the cost of these components. First, the material choice is a primary cost driver; stainless steel is generally more expensive than carbon steel due to raw material costs and processing requirements. Second, customization adds a premium. Attributes such as "Customized Size," "Customizable Thread Standard," and "Customizable Surface Treatment" require additional manufacturing steps, tooling, and quality checks, all of which increase the unit cost. Third, the complexity of the connection mode, such as a specialized flange connection versus a standard threaded connection, influences the machining time and material usage.

Packaging also contributes to the overall cost. Products are often shipped in export cartons or export wooden cases, with specific single package sizes noted as 20x20x20 cm. For heavy items, the single gross weight can be up to 10.000 kg, which significantly impacts shipping logistics and freight costs. Buyers should factor in these logistical expenses when comparing total landed costs from different suppliers. Additionally, the "Date of Delivery" status, which can range from "Goods in Stock" to custom lead times, affects pricing. Immediate availability often commands a premium, while longer lead times for custom orders may offer cost savings but require careful inventory planning.

Typical Applications and Industry Requirements

Right angle hydraulic swivel unions are versatile components utilized across a wide array of industries. The observed application data highlights their use in automotive repair, agricultural irrigation, heating systems, and the power industry. In the construction engineering and shipbuilding sectors, these unions are essential for hoisting machinery and crane operations, where fluid transfer must occur while the machinery rotates. The petrochemical and metallurgical industries rely on these components for handling high-pressure fluids in harsh environments, necessitating robust materials like stainless steel.

The specific application dictates the required specifications. For instance, in agricultural irrigation, the union must handle water efficiently and resist outdoor corrosion. In contrast, applications in the petrochemical industry require components that can withstand higher pressures and potentially corrosive chemicals. The "Machine" type, such as a crane, also influences the selection; a crane operating in a heavy-duty environment requires a union with a high maximum pressure rating and a robust build. The "Warranty" period, often listed as 1 year, serves as a baseline for quality assurance, but buyers in critical industries may seek extended warranties or specific performance guarantees based on their operational intensity.

Furthermore, the "Pipe Class" is noted as "Not Rated" in some listings, which suggests that buyers must define the pressure class requirements themselves based on their system design.
