LIGHTWEIGHT HAZARDOUS CHEMICAL SUBSTANCE STORAGE AND TRANSPORTATION TANK AND RAILWAY TANK CAR USING SAME

摘要

Disclosed are a lightweight hazardous chemical substance storage and transportation tank and a railway tank car using same. Under the premise of meeting the height and width limits on a transportation line, the volume of the storage and transportation tank is increased, the transportation efficiency is improved, it is guaranteed that the gravity center of the storage and transportation tank does not exceed a safety threshold value, and the safety of transportation is ensured. The storage and transportation tank comprises a front sealing head (31), a barrel (32) and a rear sealing head (33), wherein the barrel (32) comprises two end right frustums (321)and two middle straight frustums (322); and the small ends of the two end right frustums (321) are respectively connected to the front sealing head (31) and the rear sealing head (32), the large ends of the two end right frustums (321) are connected to the small ends of the two middle straight frustums (322), and the large ends of the two middle straight frustums (322) are connected to each other.
