What type of tanker has a maximum internal pressure ranking from 100 to 600 psi?

The type of tanker that has a maximum internal pressure ranging from 100 to 600 psi is known as a "high-pressure tanker." These tankers are designed to transport gases and liquids that require higher pressure to remain in a liquid state, such as liquefied natural gas (LNG) and certain chemicals. Their robust construction allows them to safely handle the elevated pressures during transportation and storage.
