about pre-insulated steel pipes, involving multiple standards such as EN 253, EN 448, EN 488, EN 489, as well as material standards such as API 5L, ASTM A53, etc. First of all, I need to sort out the specific content and application scope of these standards. According to the information I have searched, EN 253 mainly targets steel pipe components of direct buried hot water pipe networks, while EN 488 involves steel valve components.
Double pre-insulated pipes are designed and manufactured to be used in hot water, hot oil, industrial lines and vapor lines at temperatures in between 120-450 ℃.
Pre-Insulated Pipes • Heat loss during transfer is at a minimum level. • Provides ease of use, transportation and assembly. • It is resistant to corrosion. • It has a lifetime of more than 50 years under 120 ° C continuous temperature. • Due to the heat conduction coefficient of the polyurethane used, there is less heat loss compared to the classical system.Because the sheath pipe is HDPE, it provides 100% sealing.

abtersteel manufactures its product range for district cooling strictly in compliance with EN17415-1, EN17415-2, EN17415-3, EN489 and other relevant standards, which will ensure a technical lifetime of minimum 50 years when designed and installed correctly.
Black Steel Pipe and Galvanized Steel Pipe are both types of steel pipes used in various applications, and their main difference lies in their coating and resistance to rust and corrosion.
A hard, mechanically strong top coating for all fusion bonded epoxy pipeline corrosion protection coatings. It is applied to the base coating to form a tough outer layer that is resitant to gouge, impact, abrasion and penetration. abter steel is specifially designed to protect the primary corrosion coating from damage during pipeline directional drilling applications, bored, river crossing and installation in rough terrain.
