API 5CT seamless steel tube for Oxygen, water and oil
pipelines used in oil and gas industry.
1. Product Description
API 5CT is a seamless steel pipe for petroleum casing, which is mainly used to extract underground petroleum resources. The product materials mainly include J55, K55, N80, L80 and P110. Customers can choose their own products according to their own needs. Products of each material have different inspection requirements, chemical compositions and physical properties. Please refer to the table below for specific chemical compositions and physical properties,
The processing forms of pipe end include: P-flat head, N-NO thickening, U-extra thickening, T and C-thread band coupling, I-integral joint, S-short round thread, L-long round thread and B-partial trapezoid thread.
Matching coupling: standard coupling, special space coupling, special bebellde coupling, and special diameter coupling. If there are special requirements, please quote and make notes when placing an order. It is our pursuit to meet the different needs of customers,
The API 5L pipeline pipe for export can be painted and marked on the surface, threaded and blunt on both ends, with pipe caps and protective covers on both ends, with various export packaging methods to ensure the safe transportation of products,
Our products sell well all over the world, and high quality products are unanimously recognized by customers.
