   Inner Mongolia Rational Industry Limited (IMRI) is a supplier of anti-corrosion coating and seamless steel pipes. We have two production lines for external anti-corrosion coating, one production line for internal coating and one production line for insulating tubes. We mainly engage in accessory processing for Baotou Steel. At the same time, IMRI is a distributor of Baotou Steel''s steel products. We have established a long-term strategic co-operation relationship with Baotou Steel.
   Core members of our team have more than 10 years'' experience in the field of anti-corrosion coating production as well as anti-corrosion equipment designing. They are familiar with the purchasing requirements on anti-corrosion coating and steel pipes from international major oil companies. They also have supply experience for such companies like SONATRACH, BP, OGDCL, MRC, OXY, PDVISA, OMAN, LUK OIL, SHELL, ITOCHU, and BASF, etc.
   IMRI specializes in the process of internal and external pipe-coating, including 3LPE, 3LPP, FBE, and insulating tubes, etc. Our company is a distributor of Inner Mongolia Baotou steel Union Co., Ltd. The main products are seamless pipes, gas cylinder tubes, oil casing, hydraulic pillar tubes, alloy tubes, steel plates, wire rod coils, shape steels, and rail steels, etc.
   Founded in 1954, Baotou Steel is one of the steel companies who has the most complete industrial chain in China. It can produce 17 million tons of steel per year. It is a large integrated enterprise with iron ore, rare-earth ore, smelting, casting, rolling, pipe processing, testing, researching and transportation.

There are 5 production lines for seamless pipes in Baotou Steel. Among these, 2 PQF production lines are the most advanced in the world, and 1 MPM two-roll continuous rolling automatic production line is included.
   Combining its own advantage of coating technology with Baotou Steel''s advantages of products diversification, excellent quality, and low cost, IMRI can really achieve one-stop supply of anti-corrosive steel pipes.

Details

The main performances of internal coating:

Items	Performance index	Test method
Pinhole test	Pinhole dispersion shall be held to a minimum	API RP 5L 2-2002
Dry film thickness	≥80μm	API RP 5L 2-2002
Cure test	No softening, wrinking or blistering	API RP 5L 2-2002
Adhesion test	No loss of adhesion	API RP 5L 2-2002
Bend test	No loss of adhesion, spalling,crack	API RP 5L 2-2002
Soaking test	No loss of adhesion,softening, wrinking or blistering	API RP 5L 2-2002
Stripping test	Flake off,present powder particles when rolled	API RP 5L 2-2002

Almost all along distance transmission pipeline use liquid epoxy materials for internal coating to reduce flowing resistance, the coat improve the liquidity of medium, increasing the throughput and reduce the engineering cost, save power consumption.

We perform this coating as per for API PR-5L, etc.
