Standard of SSAW steel pipe 3PE anticorrosive

Anticorrosive steel pipes are divided into anticorrosive SSAW steel pipes, anticorrosive LSAW steel pipes and anticorrosive seamless steel pipes according to the type of steel pipes. The common form of anticorrosive steel pipes is 3pe anticorrosion.

The domestic implementation of the SY/T0413-2002 standard, the standard mainly regulates polyethylene and high-density polyethylene, and the Vicat softening point is no less than 110; the thickness of the outer anti-corrosion layer is determine by Germany Standard DIN30670-1991, which mainly are low-density and medium-density polyethylene. Greatly improve the impact strength of the 3PE anti-corrosion layer. SY/T0413-2002 greatly improved the peeling strength and impact resistance of 3PE anticorrosion layer, and clearly stipulated the carbon black content of some special materials, stipulated the mechanical strength and weather resistance of 3PE anticorrosion layer, and enlarged the joint The peel strength (that is, the peel strength of the heat shrinkable sleeve and the heat shrinkable tape to the primer steel) sampling frequency.

The anti-corrosion SSAW steel pipe 3PE structure anti-corrosion layer combines the advantages of high-density polyethylene coating and fusion-bonded epoxy powder. The epoxy powder of the system is firmly bonded to the surface of the steel pipe, and the high-density polyethylene is used to resist mechanical damage. The special adhesive layer between the two layers makes the three of them form a molecular bond composite structure, thereby achieving a good combination of anti-corrosion performance and mechanical properties.
