Galvanized Steel Seamless Pipe

Galvanized seamless steel pipe refers to the manufacturing process of steel pipe is divided into welding and seamless. Advantages of galvanized steel smls pipe: The surface is coated with a layer of zinc, so it is more resistant to corrosion and rust, and it is lighter and more durable. It has high strength and can withstand greater pressure, but the wall of the seamless steel pipe is thicker and heavier, and the cost is relatively high. Applications of galvanized and seamless pipes: Galvanized pipes are used in a wide range of applications, including natural gas, petroleum, chemical and other industrial fields, as well as pipe piles for trestle bridges and support pipes for mine roadways. Galvanized seamless steel pipes are widely used in the manufacture of ring parts from steel pipes for oil drill pipes, automobile drive shafts, steel scaffolding, etc.

    Introduction

    There are two types of galvanized seamless steel pipes: hot-dip galvanized (hot-dip galvanized) and cold-dip galvanized (electro-galvanized). Hot-dip galvanizing has a thick galvanized layer, which has the advantages of uniform coating, strong adhesion, and long service life. However, the cost of electro-galvanizing is low, the surface is not very smooth, and its corrosion resistance is much worse than that of hot-dip galvanized pipes. How to test the quality of galvanized seamless steel pipe?
    According to the requirements of the standard, the galvanized pipe manufacturer pointed out that the inspection content of the geometric dimensions of the galvanized seamless pipe mainly includes the wall thickness, outer diameter, length, curvature, ovality, and end shape of the galvanized seamless pipe.
    1. Wall thickness inspection
    The tool used for wall thickness testing is mainly a micrometer. When checking, use a micrometer to measure the wall thickness of the galvanized pipe one by one. Before the inspection, first, check whether the certificate of the micrometer is within the validity period, and check whether the micrometer is aligned with the zero position and whether the rotation is flexible. There should be no scratches or rust spots on the measuring surface, and it can be used only after passing the inspection. When checking, hold the micrometer bracket with your left hand, and rotate the excitation wheel with your right hand. The screw rod should coincide with the diameter of the measuring point, and the end face should be measured at no less than 6 points. If the wall thickness is found to be unqualified, it shall be marked.
    2. Outer diameter and ovality inspection
    The tools used for outer diameter and ovality inspection are mainly calipers and vernier calipers. When checking, use a qualified vernier caliper to measure the outer diameter of the galvanized pipe one by one. Before the inspection, first, check whether the certificate of the caliper is within the validity period, and check the used caliper with a vernier caliper to see if there are scratches or rust on the measuring surface. It can be used only after passing the test. test. When checking, the caliper should be perpendicular to the axis of the galvanized pipe, and the galvanized pipe should rotate slowly. If the outer diameter of the measuring section is found to be too large or too small, it shall be marked.
    3. Length check
    The tool used to check the length of the galvanized seamless pipe is mainly a steel tape measure. When measuring the length, align the “O” point of the tape with one end of the galvanized pipe, and then pull the tape tightly so that the scale surface of the tape is close to the surface of the galvanized pipe. The length of the tape at the other end of the galvanized pipe is the length of the galvanized pipe.
