Tight HeadSteel Drum
Major Application
Used for chemical products of general quality,petroleum, gasoline and other liquid oils such aslubricants.

Te c h n o l o g y①Triple seaming is a sturdy seaming method
suited for drums containing dangerous goods.
②Internal cleanliness has been enhanced by
the application of a full automatic production
process and phosphate coating treatment
system.

Type and Featuresof Internal Surface Coating Paint
1.Properties and Features of Internal Surface Coating Paint
Properties and features of representative internal coating paint are shown below. For further information on this and othertypes of paints available to our customers, please contact our sales divisions.
Epoxy-phenolic

Phenolic

Code nameNSP

4A

Coatingthickness

10〜30μm

6〜12μmColor tone

Yellowish grayTransparent brown

FeaturesThis type of coating has excellent adhesion tometals and is highly flexible as well as durable
against weak alkaline substances. Since internal
odor is hardly present, this type of coating issuitable for containing foods and perfume too.

This type of coating provides low penetration
characteristic and is durable against organic
solvents or weak acids with a drawback of low
flexibility. Due care, however, should be taken
for alkaline or water solution type contents.

Type2.Internal Coating Quality
The following table shows examples of results of standard specimen tests made to evaluate the internal coating quality.
Values shown in the table, however, are the test results for each corresponding test, and not the specification value of ourproducts. Such test results may vary depending upon the process of surface pretreatment. For further information, pleasecontact our sales divisions.

Dangerous Goods Container
Dangerous Goods Container
Recommendations on the Transport of Dangerous Goods (UN Recommendations Chapter 9) were issued by the UnitedNations, the Committee of Experts on the Transport of Dangerous Goods, to secure the safe transport of dangerous goods
in packages where they are packed in containers for transport. Based on these recommendations, the IMDG Code wasformulated to specify containers suitable for the international sea transportation on dangerous goods. These container
specifications are also adopted in Japanese laws and therefore must be applied to dangerous goods containers forinternational transport. Similar container specifications have been also adopted for domestic transport of dangerous goods.

Containers and Packagings
The type of containers and packagings are drum, wooden barrel,box, jerrican, bag and composite containers. The necessary
performance items required for containers alone are specified ascontrol items, and although there is a simple construction
specification, there are no shape or dimensional specifications.
Three different performance specifications have been set up, andthe proper selection must be made according to the class ofdangerous goods to be transported. Since the class of container
and the type container and packagings are specified for eachtype of goods, reference to the IMDG Code is requested for sea
transport, and to the Dangerous Goods Regulations in Fire
Service Law for domestic transport.
1）High level dangerous goods……Packing GroupⅠ
2）Medium level dangerous goods……Packing GroupⅡ3）Low level dangerous goods……Packing GroupⅢ

ADR

All containers and packagings for dangerous goods must be
tested for performance, and required markings must be put on
containers and packagings that have passed the test.
