The first domestic 8500m CT130 steel grade ultra-high strength continuous pipe was born in Baoji Steel Pipe Company

Recently, the reporter learned from PetroChina Baoji Petroleum Steel Pipe Co.
, Ltd.
that the first domestic plate length of 8500 meters, diameter 44.
45 mm, wall thickness 3.
68-4.
8 mm, steel grade CT130 ultra-high strength variable wall thickness continuous pipe successfully off the line, once again refreshing the domestic single disc length, wall thickness span the largest ultra-high strength continuous pipe record, marking China's continuous tube manufacturing technology to achieve a new leap
.

Baoji steel pipe technicians measure pipe diameter

In recent years, with the continuous increase of domestic deep oil and gas exploration and development, ultra-deep wells, ultra-long horizontal wells, ultra-high pressure operations have put forward higher requirements for the strength and length of continuous pipes, Baoji Steel Pipe adheres to the concept of "achieving customers is achieving oneself", and continues to build continuous pipe equipment sharp tools to meet the special needs
of oil and gas exploration and development for pipe equipment 。 In this production process, the company solved the 8500 meters length of steel belt coiling, ultra-high strength molding and sizing equipment brought by the problem, overcome the wall thickness range span, small diameter and thickness ratio caused by the manufacturing process, after nearly 7 hours of continuous and stable production, to create the first domestic 8500 meters, CT130 steel grade ultra-high strength variable wall thickness continuous pipe
.
After testing, all the properties of the product meet the standard requirements
.

The first 8500 meters, CT130 steel grade ultra-high strength variable wall thickness continuous pipe in China was successfully rolled off the production line
in Baoji steel pipe.

"CT130 ultra-high strength variable wall thickness continuous pipe as the current continuous pipe top products, with ultra-high pipe strength, super anti-extrusion and torsional resistance, and at the same time, through the variable wall thickness technology, in the case of increasing length, the weight does not change much, which is the 'fragrant food' of unconventional oil and gas development such as deep oil and gas resources and shale gas
.
" Bi Zongyue, chief technical expert of Baoji Steel Pipe, said
.

As the only continuous tube research and development and manufacturing enterprise of PetroChina, Baoji Steel Pipe relies on the technology, talent advantages of the National Pipe Research Center and the pipe making technology experienced for more than ten years, and continues to increase the intensity of scientific and technological research and development, not only upgrading the steel grade of continuous pipe products from CT70 to CT150, but also custom-developed corrosion-resistant alloy continuous pipes such as 2205 and super 18 chromium, non-metallic continuous pipes, multi-channel continuous pipes and other high-end products, which are exported to Russia, the United Arab Emirates, and the United Arab Emirates while meeting the exploration and development of major oil and gas fields.
Ukraine and other more than 10 countries and regions
.
In 2021, the continuous pipe production and sales volume of Baoji steel pipe exceeded 10,000 tons, hitting a record high
.
In January this year, the output of continuous pipe was more than 700 tons, creating the best result
in the same period since it was put into operation.
