CRA CLAD OR LINED STEEL PIPE

Standard: API Spec 5LD, API Spec 5LC, DEP 31.40.20.32, DNVGL-ST-F101, according to agreement etc.

Interface type: Screw thread, groove, welding and flange connection.

Application: Widely used in oilfield, chemical engineering electricity etc.

Principle: The outer base pipe is responsible for pressure bearing and rigid support of the pipe, while the inner

liner pipe is responsible for corrosion resistance and wear resistance

Delivery Condition: Mechanical Bonded and Metallurgy Bonded

ADVANTAGES OF CLAD PIPES

1. CO +CL environmental solution

Form: It is mainly lined with 316L Metallurgy clad bend pipe products, the base pipe can adopt various carbon steel pipes that meet relevant standards (including 20G , 20#, Q235, L245/L360/415, X45/X52/X65, etc.) according to the pressure, temperature, and cost efficiency.Purpose: To solve the corrosion problem of carbon steel caused by the mixed CO2 and CL gas and liquid, ensure the strength and
