During the construction and installation of chemical tank farms, high-quality seamless pipelines that are compatible with the properties of commonly used solvents should be selected, while also taking into account the differences in the physicochemical characteristics of various solvents.

First, the sealing materials used at the interface between the piping and the vessel must exhibit chemical resistance compatible with the properties of the solvents being handled. For example, when processing highly polar ketones, esters, and similar solvents, ordinary rubber seals should not be employed to prevent swelling and corrosion that could lead to seal failure. When handling low‑flash‑point, flammable and explosive ether‑type solvents and low‑molecular‑weight alcohols, all welds must undergo rigorous nondestructive testing to identify defects and eliminate any risk of leakage. In addition, the appropriate pipe diameter should be selected based on process parameters such as flow rate and pressure, ensuring that the pipeline’s pressure‑bearing capacity meets the transport requirements. A corrosion allowance should also be provided to account for long‑term corrosion degradation, thereby extending the service life of the equipment.

The commonly used flanged connections mainly include: There are two types: slip-on flanges and necked weld‑on flanges. The difference between the two is: Flat-welded flanges have a simple structure, It has no neck and is directly slipped onto the weld, making it suitable for low-pressure, cost-sensitive applications. Welding neck flange With a conical neck and a butt-welded joint between the pipe opening and the neck, this design offers enhanced structural integrity, making it ideal for high-pressure applications that demand superior connection strength and sealing performance, while delivering greater durability and reliability.
