API SPEC 5L steel pipe is made for pipeline transportation systems in the oil and natural gas plants.  API 5L has its special characteristic for conveying, water, gas and oil. This kind of oil pipe size range can be made per customer’s need, so the only limit is manufacturer’s capabilities. It is strictly manufactured following ISO 3183 standards, which is specially made for the pipeline systems at material, equipment, off shore gas industries.
