Api 5ct Pipe
Api 5ct Pipe
Api 5ct Casing Pipe Manufacturers
API 5ct Pipe is a specification of pipes that are used for casing or tubing in industrial gas lines and in tube well. There are different levels of specification such as PSL1, 2 and 3. The Api 5ct Pipe has different carbon and chromium contents in the different product specification levels. [Company Name] is one of the leading Steel Casing Pipe Manufacturers producing all product specifications. These are used in transportation of oil and gas, water and other fluids as necessary. The Api 5ct Pipe Sizes vary in diameter, wall thickness and length. The outer diameter ranges from 6mm to 219mm, the wall thickness ranges from 1mm to 30mm and the length ranges up to 12000mm. The Api 5ct Casing Pipe comes in different steel grades.
The grades include J55, K55, N80, L80 and P110. These are different mechanical property oriented grades. The pipes come in different connection types as well. The Api-5ct Pipe Specification includes short round threaded, non – upset tubing, integral joint tubing, external upset tubing, extreme line casing, buttress thread casing and long round thread casing as well. The Api 5ct Pipe Price varies based on the grade, diameter, wall thickness and length of the pipes. Please contact us to know more about these pipe products.
