Oil and natural gas are important energy and chemical raw materials. Stainless steel pipes are inseparable in the whole process of oil and gas exploration, drilling,
transportation, refining and long-distance transportation to users. The oil and gas drilling is the largest of seamless stainless steel pipes. Professional users.
The most expensive oil casings are generally made of carbon-manganese steel and low-alloy steel with a yield strength of 400-800 MPa. For oil and gas wells with acid
gas (C02, C02 + H2S) and chloride (CL-) corrosion, corrosion resistant stainless steel is required.
Even nickel-based alloys are used for oil casings and stainless steel pipes. This is an area where stainless steel pipes have broad application prospects in oil and gas development.
The problem of CO2 corrosion during oil and gas production has been alleviated by the addition of preservatives. However, there is always an unstable effect of the corrosion inhibitor,
and the effect is worse when the temperature is high; the environment is polluted and the life cycle cost is
A series of problems higher than stainless steel.
Especially in the development of Beihai Oilfield, the use of duplex stainless steel has completely solved the problem of long-term safety of CO2 corrosion oil and gas wells. However,
due to the high price of duplex steel, the use is limited.
Since the early 1980s, seamless pipe production plants have developed their own series. In the initial stage of industrial production, it was produced by an extruder, and the output was limited.
Concentrating on the continuous rolling mill unit (small caliber) in the 1980s and 1990s
The technical problems related to the production of C13Cr pipes on automatic rolling mills (large and medium caliber) were tackled and the main equipment was modified accordingly.
The production of C13Cr-based chrome-based stainless steel seamless pipes has increased significantly.
It accounts for half of the world's stainless steel oil pipe market.
The role of seamless steel tubes in oil exploration is irreplaceable. Manufacturers producing seamless steel tubes are also actively seeking to reach long-term cooperation with customers in
the petroleum industry. Zibo Baishun Stainless Steel Co., Ltd. was founded in 2008. With nearly 10 years Development in this industry
And its own advantage,we have Vietnam, Laos, Cambodia, Thailand, Myanmar, Malaysia, Singapore, Indonesia, Brunei, Philippines, East Timor clients.our company has established a strong trade network and stable customer base.
