As industries have become more aware and responsive to environmental issues, loading systems offer a sound solution to the extremely critical process of transferring hazardous products from bulk-storage tanks to rail or road vehicles. Custom loading arms are manufactured with regard to the unique application and custom-design specifications of the customer. In order to design an application-specific custom loading arm, the following are considered:
- Liquid product to be handled (temperature and pressure)
- Type of tank or container to be used
- Flow rate
- Adequate capacity without excessive pressure drop
- Physical facility dimensions and limitations
- Adequate horizontal and vertical range
- Ease of operation/maintenance
- Special requirements
- Factory pre-assembly and testing
Within the limits of design and functionality, nothing is too special. As industries have become more aware and responsive to environmental issues, loading systems offer a sound solution to the extremely critical process of transferring hazardous products from bulk storage tanks to rail or road vehicles. All units can be factory pre-assembled and tested, and all OPW Engineered Systems products are built to the highest quality standards.
