The performance characteristics of

Corrosion resistance, green environmental protection, long life, convenient installation

Use optimal powder

Oriental steel pipe with the world top 500 American dupont cooperation, joint research and development of the east steel pipe special jinsu powder, using high density polyethylene powder, compared with low density polyethylene powder particles finer, melt index is higher, ensures the uniformity of coating, to avoid the pinhole, greatly enhance the coating adhesion and pipeline service life.

Three layer anticorrosive structure

In epoxy layer thickness > 0.4 mm hot melt, the sinter winding outside polyethylene coating thickness > 3 mm, adopts low-voltage high-density polyethylene + + hot melt adhesive bonded epoxy three-layer anticorrosive, good chemical resistance, solvent resistance, can resist by transmission medium of H2S, CO2 and O2, acid, alkali, salt, organic substances such as chemical corrosion, and can long-term exposure to saline groundwater and sea water, such as a variety of organic acids in soil microbial corrosion material, strengthen the anticorrosion performance, resistance to knock against.

Inner wall perfectly smooth

Almost harsh pretreatment process, resulting in high adhesion, uniform, smooth inner surface, less resistance for you to save time and effort.

The tube body substrate is of better quality

Spiral welded pipe body with wide coil plate, more than the traditional narrow strip steel welded tube body strength big, outer coating, coating using high pressure winding technology greatly improves the compactness, tenacious wear-resisting coating, impact resistance and good resistance to bending, can effectively prevent damage of construction in the mechanical and the use of plant roots and soil environmental stress damage.

 The full name of TPEP anticorrosive steel pipe is inner fused epoxy outer 3PE anticorrosive pipe. On the basis of drawing on foreign advanced production technology and 30 years' anticorrosion production technology, our company has independently developed a new anticorrosion production line for large-caliber pipelines, which can produce 2PE, 3PE, hot-melt epoxy for internal and external coating, PE/2PE/3PE for internal and external coating and PE/2PE/3PE for internal and external coating. The inner wall of the tube is anticorrosive by means of thermal spraying epoxy powder, which is evenly wrapped and coated on the surface of the tube after being heated and fused at high temperature, and the products coated both inside and outside can be coated and cured at the same time, and the film can be formed at one time.

Product comparison

The unique coating technology of dongfang steel tube enables the coating powder to adhere to the pipe body evenly, with stronger adhesion. Inferior products on the market wall coating is not uniform, coating thickness and size, coating easy to peel off.

Outer 3PE winding uniform, smooth surface, no fold, bulge, bubble phenomenon, coating adhesion is high. The coating on the outer wall of inferior products is not evenly wound, which is easy to blister, bulge and crack, which affects the adhesion of the coating on steel pipe.

Our company adopts high-quality powder coating, the product in the incubator of minus 30℃, more than 1 hour, after bending 2.5 degrees coating without cracking. Cracks and fine lines appear in the coating of the outer and outer wall in the bending test, and the bending resistance of the coating is poor.

In indentation hardness test, the coating is at 70℃ for more than 1 hour. The hardness test of the coating is ≤0.2mm. The outer coating has high strength and good anti-knock performance. After indentation hardness test of inferior products on the market, the hardness of coating is greater than 0.2mm, and the anti-knock performance of coating is poor.
