    ASTM A106 Wear Resistant Pipes

    ASTM A106 Large Diameter Welded Steel Pipe High Pressure Oil And Gas Transportation

    Welded steel pipes refer to steel pipes with seams on the surface that are welded after bending and deforming steel strips or steel plates into round or square shapes. The blanks used for welded steel pipes are steel plates or strip steels.


    T-welded steel pipes have strong corrosion resistance in acidic environments when they contain Ni. In environments containing sulfuric acid or hydrochloric acid, the higher the Ni content in T-welded steel pipes, the stronger the corrosion resistance. Under normal circumstances, only adding Cr to T-welded steel pipes can prevent corrosion. The poor condition of the edge of the steel strip is another important reason for the wrong edge. The influence of changes in mass flow, heat flow density and structural parameters (the ratio of spiral curvature diameter to T-welded steel pipe diameter Dc/D) on the heat transfer coefficient of saturated bubbly boiling in a vertical spiral tube.
    In the production of T-welded steel pipes, the wrong side occurs from time to time, and there are many influencing factors. In production practice, steel pipes are often degraded due to dry misalignment and excessive tolerance. Therefore, it is necessary to analyze the causes of wrong edges of spiral steel pipes and preventive measures.


    Due to the poor shape and dimensional accuracy of the head and tail of the untrimmed steel strip, it is easy to cause the steel strip to bend hard and cause misalignment during butt joints. Simulation parameter range: vertical pipe: pipe diameter D=lOmm, pipe length L=660mm; three types of vertical T-welded steel pipes: pipe diameter D=10mm, the ratio of the curvature diameter of the T-welded steel pipe to the spiral pipe diameter changes as Dc /D=15, 20, 25, spiral pitch Pt=20mm, tube length L=503mm, L=660mm, L=817MM. Mass flow G=200~400Kg/(m'2·s), heat flux q=5~15KW/m'2, saturation pressure p, saturation=0.414880MPa, saturation temperature T, saturation=283.15K.


    Classification of welding methods
    According to different welding methods, it can be divided into arc welded pipe, high frequency or low frequency resistance welded pipe, gas welded pipe, furnace welded pipe, Bondi pipe, etc.
    Electric welded steel pipe: used in oil drilling and machinery manufacturing.
    Furnace welded pipe: can be used as water gas pipe, etc., large-diameter longitudinally welded pipe is used for high-pressure oil and gas transportation, etc.; spiral welded pipe is used for oil and gas transportation, pipe piles, bridge piers, etc.
