Painting

introduction of painted steel pipe
painted steel pipe is to spray different colored coatings on the surface of the steel pipe in order to improve the corrosion resistance and aesthetics of the pipe. painted steel pipes include spray-coated steel pipes and painted steel pipes.

spray coated steel pipe is first acid-washed, galvanized and phosphated, and then electrostatically sprayed. the advantages of this method are strong adhesion of the coating, not easy to peel off, good protective performance, bright and beautiful colors; the disadvantage is that the cost is relatively high, and special spray equipment and highly skilled personnel are required to operate.

painted steel pipe is directly spray-painted different colored coatings on the surface of the steel pipe without acid washing, galvanized nor phosphating, in order to improve the corrosion resistance and aesthetics of the pipe. the advantages of this method are relatively low cost and simple and convenient processing; the disadvantages are weak adhesion, difficult to achieve long-term corrosion resistance effect, and relatively monotonous color.

when using painted steel pipes, it is necessary to select the appropriate paint type, color and thickness according to the specific conditions of use and requirements. at the same time, it should be ensured that the surface of the steel pipe is dry, clean and smooth to ensure the coating adhesion effect and service life.

  • Pipe Threads
    NPT (National Pipe Thread) and BSPT (British Standard Pipe Thread) are two commonly pipe thread standards. NPT threads are commonly used in North America and BSPT threads are more commonly used in Europe and Asia. Both standards have tapered threads that create a tight seal when tightened together. Widely used in water, gas, oil and other pipelines connection.
  • Rectangular Steel Tube,Elbow,External Polyethylene Coating pipe
    We offer precision cutting on lengths of pipe ranging from 2 inches to 60 feet, and diameters from 2” thru 48”. The type of cutting used depends on both the size of the pipe and the required precision. The tolerance ranges from 1/8” thru 48”.
  • steel pipe welding, Pipe welding
    Pipe welding or pipe connection is a method where two pipes are joined together. This process can be achieved by various welding methods, such as arc welding, MIG welding, TIG welding and several other welding techniques. We weld all kinds of piping constructions of different sizes and shapes.
