热熔浸稀土铝合金油套管(注水井管)及抽油杆
Hot-Dipped Rare Earth Aluminum Oil Pipe (Water Tubing) and Oil Pipe Rod


石油开采所用的油套管,注水井管,抽油杆,集输管的腐蚀破坏问题是世界性难题,长期以来,国内外都致力于开发防腐性能好,使用寿命长的安全可靠产品,其研发路线分为两条:一是采用高品质合金钢;二是对其表面进行防腐处理,;前者成本太高,后者存在很多缺陷,鉴于此,我公司利用《大型钢件热熔浸铝方法》的专利技术,研发出热熔浸稀土铝合金油套管,注水井管,集输管,抽油杆等系列产品。其技术和性能有如下特点:

一、技术上采用二浴法工艺:通过盐浴对钢基体表面进行充分净化和浸润,使钢件达到和铝液相近的温度,提出后迅速置入稀土铝液中,使其铝铁合金层更致密,铝层更均匀,彻底避免了针孔漏镀。另外,根据牺牲阳极保护阴极的原理,我们将钢管浸铝后再进行丝扣加工,以保证丝扣质量要求标准。对抽油杆,我采取先浸铝,后调质的工艺方法,即将抽油杆的半成品进行热熔浸铝,然后进行丝扣加工和调质处理,这样即保证了产品的力学性能,又保证了产品的耐腐蚀性能。

二、防腐性能:本产品在油气井腐蚀环境中具有极强的耐蚀性能,致密、完整、稳定的AI2O3氧化膜对电化学腐蚀具有很强的阴、阳极阻滞作用,在高温高压,特别是CO2、H2S、CI–共存环境中有着很高的耐蚀性能,可避免硫化物应力开裂和氢致开裂。另外,对细菌微生物的腐蚀也有着很好的防垢作用。

正因为以上原因,本产品与高品质合金管及其它防腐方法的钢管有着极好的性能价格比,目前在大港油田采油三厂,辽河油田已经开始使用,效果很好。


Oil Pipe, Water Tubing, Oil Pumping Rod and Piping Line corrosion damages are the global problem in the oil industry. For a long time, at home and abroad , industry experts are committed to the development of good corrosion resistance, long life-span, safe and reliable product. The R & D is divided into two directions: one is made of high-quality alloy steel; the second is its surface Anti-corrosion treatment. The former is too costly. In the later, there are many defects. In view of this, Anshan Yin Ma uses the "Large-scale steel Hot-Dipped Aluminum" patented technology, developed the Rare-Earth Hot-Dipped Aluminum Oil casing pipe, Water Tube, Oil Flow pipe, Oil Pumping Rod and series of products. Its technical and performance characteristics are as follows:

I. The process is “Dual-Bath Technology”: The steel substrate is cleaned and soften by the hot Salt-Bath; to raise the substrate temperature close to the Aluminum molten temperature. After the Salt-Bath, the steel substrate is removed quickly into the molten Aluminum. This process ensure the Aluminum-Ferrous Alloy more densely combined, more evenly coated and completely avoid the pin-hole formation.

In addition, according to the anode cathodic protection principles, the pipe will be threaded to ensure the quality requirements of the threading standard. On the Oil Pumping Rod, it is first dipped in Aluminum, then special process for quality. This is to hot-dip the semi-finished rod in Aluminum, then thread processing and conditioning treatment. This guarantees the product mechanical properties and guarantees product corrosion resistance factor.

II. Anti-corrosion property: This product operates in oil and gas wells of highly corrosive environments.It  exhibits great corrosion resistance, compact, complete and stable oxide AI2O3 film has resistance to the electro-chemical corrosion. It has a strong cathode and anode blockade at high temperature and pressure. It is especially evidence in CO2, H2S, CI- coexistence environment with a high corrosion resistance. It can avoid sulfide stress cracking and hydrogen induced cracking. In addition, under the bacterial microbial corrosion and scale it also has a very good effect.

Because of the above reasons, the product compared with high quality alloy steel pipe and other anti-corrosion method has an excellent price-performance ratio. Currently, Dagang Oilfield #3 Plant and Liao He Oil field, had begun to use with excellent results.
