The construction of long-distance oil and gas pipelines in China has entered the era of all-terrain automatic welding
On April 8th, the "Four-All" pipeline welding inspection robot technology equipment system independently developed by our country was put into large-scale application, significantly improving the construction efficiency. This marks a leap from "segmented manual welding" to "all-terrain automatic welding" in the construction of long-distance pipelines in our country.
The "Four-Al
What are the selection conditions of electric butterfly valve and pneumatic butterfly valve?
Electric butterfly valve has the advantages and uses
Electric butterfly valve is a very common pipeline flow regulation device, widely used, involved in many fields, such as the regulation of water flow in the reservoir dam of hydraulic power plant, industrial fluid flow regulation in the factory, etc., the following take you to understand the characteristics and advantages of electric
A scientific and technological achievement of Southwest Oil and Gas Field Company has reached the international advanced level

After the annual output of CBM reached 2.6 billion cubic meters in 2024, equivalent to 2.07 million tons of crude oil equivalent, and the first medium-shallow CBM field with an annual output of
The 21st Tianjin Industry Fair 2025 intelligent pump valve exhibition
The 21st Tianjin Industry Expo (CIEX) will be held at the National Convention and Exhibition Center (Tianjin) from March 6 to 9. It serves the whole industrial chain of industrial manufacturing, and has professional exhibition areas such as machine tools, robots, automation, new energy, electronic manufacturing, and intelligent pumps and valves, providing a one-stop exhibition platform for prom
In the fluid piping system, the valve is the control element, its main role is to isolate the equipment and piping system, regulate the flow rate, prevent backflow, regulate and discharge pressure. Because it is very important to choose the most suitable valve for the pipeline system, it is important to understand the characteristics of the valve and the steps and basis for select
1. Valve stem corrosion and protection
Main causes of valve stem corrosion:
The corrosion damage of the valve body is mainly caused by the corrosive medium, and the valve stem corrosion problem is mainly the packing.
Not only the corrosive medium causes corrosion damage to the valve stem, but also the steam and water can make the valve stem and the packing contact spot. In part
China's first offshore gas storage facility officially put into operation!
At 13:00 today, with the issuance of gas production instructions, the production valve of Nanpu No. 1 gas storage well of Jidong Oilfield Branch of petrochina Co., LTD., located in Tangshan Sea of Bohai Sea, opened, and natural gas smoothly entered the production device along the process pipeline and was transported to the Beijing-Tianjin-Hebei region, which marked the official op
Yumen oilfield has entered the era of pipeline natural gas transmission
At 15:58 on November 12, with the opening of the last valve room No. 2 of Qinggao Line (Qing1 gas collection Station to Gaoshawo), natural gas in Ningqing block of Yumen Oilfield was smoothly injected into Qinggao Line pipeline, marking the era of "pipeline natural gas transmission" in Yumen Oilfield.
Previously, Yumen oil field natural gas production is small, can not be directl
Method of judging internal leakage of natural gas ball valve
Fixed shaft ball valve is commonly used on natural gas pipelines, and its general inspection method is: turn the valve to the fully open or fully closed position, and check whether there is leakage through the discharge of the valve body drain nozzle. If it can be drained clean, it proves that the seal is good. If there is always pressure discharge, the valve can be considered to be leak
Profitable oil is produced from rock joint in Tuha oilfield
Since the beginning of this year, Tuha Oilfield has established a "highway" for shale oil, tight oil and other reservoirs through various fracturing methods, so that beneficial oil can emerge from the rock joint. So far this year, the field has fracked 38,000 tons of oil, a 15% increase over the same period last year, and the cost has fallen by 10%.
The new strata in Tuha oilfiel
1. Inspection of appearance and logo
Check content: whether the appearance of the valve has defects, such as cracks, bubbles, dents, etc. Check signage, nameplate and finish for compliance.
Standards: International standards including API 598, ASME B16.34, ISO 5208, etc. Chinese standards include GB/T 12224 (general requirements for steel valves), GB/T 12237 (steel ball valv
O-type ball valve and V-type ball valve difference
Ball valve has many kinds of structure, but basically the same little difference, are the opening and closing parts for the round ball core, mainly by the valve seat, ball, sealing ring, stem and other driving devices, etc., through the stem rotation 90 degrees to achieve the opening and closing of the valve, in the pipeline for shutting off, distribution, adjust the flow size and change
