What should we pay attention to when customizing plastic-sprayed steel pipes?
Specification and size: specify the diameter, wall thickness, length and other specific dimensions of the required steel pipe to ensure that it can meet the actual use requirements. At the same time, the size tolerance range should be considered to ensure the accuracy and consistency of steel pipe size.
Material selection: according to the use environment and performance requirements, choose the appropriate steel pipe material, such as ordinary carbon steel, stainless steel and so on. There are differences in strength, corrosion resistance and toughness of steel pipes made of different materials.
Quality standards: determine the national standards or industrial standards that steel pipes should meet, such as GB/T 3091-2015 Welded Steel Pipes for Low Pressure Fluid Transportation, etc., to ensure the quality and performance of steel pipes.
Appearance quality: the surface of steel pipe should be smooth, without obvious defects such as cracks, folds, scars and burrs.
Selection of plastic powder: Choose suitable plastic powder according to the use environment and design requirements. For example, indoor plastic powder and outdoor plastic powder are different in weather resistance. Pay attention to whether the color and gloss of plastic powder meet the expectations, and ensure the accuracy and stability of color.
Pretreatment: Before plastic spraying, steel pipes need to undergo pretreatment processes such as degreasing, derusting and phosphating, so as to improve the adhesion of plastic powder to the surface of steel pipes and the anticorrosion performance.
Thickness of plastic spraying: Generally speaking, the thickness of plastic spraying is 60-100 microns, but it should be determined according to the use environment and requirements.
Curing conditions: know the curing temperature and time after plastic spraying to ensure that the plastic powder can be fully cured and form a good coating performance. Too high curing temperature or too long curing time may lead to discoloration and embrittlement of the coating, while too low curing temperature or too short curing time may lead to incomplete curing and insufficient adhesion of the coating.
Adhesion and abrasion resistance: the plastic-sprayed coating is required to have good adhesion, can be firmly attached to the surface of steel pipe, and is not easy to peel off. At the same time, according to the use scene, ensure that the coating has certain wear resistance to resist friction and collision in daily use.
In the field of deep processing of steel products, Hebei Huayang Steel Pipe Co., Ltd. has become the best choice for customizing plastic-sprayed steel pipes with its professional strength and sincere service.
First, professional production, advanced technology
Hebei Huayang Steel Pipe Co., Ltd. is located in Cangzhou City, Hebei Province, China.
