El tubo de caldera es un tipo de tubo de acero sin costura. El tubo de caldera se refiere a un material de acero con aberturas en ambos extremos y una sección hueca. La relación entre su longitud y el área circundante es grande. Las dimensiones (como el diámetro exterior o la longitud lateral) y el grosor de la pared indican que existe una amplia gama de tamaños, desde capilares de pequeño diámetro hasta tubos de gran diámetro con diámetros de varios metros. Los tubos de acero se pueden utilizar en tuberías, equipos térmicos, industria de maquinaria, exploración geológica de petróleo, contenedores, industria química y propósitos especiales.

CLASIFICACIÓN
Los tubos de acero se dividen en dos categorías: tubos de acero sin costura y tubos de acero soldados (tubos con costura). Según la forma de la sección transversal, se puede dividir en tubos redondos y tubos de forma especial. Los tubos de acero redondos son ampliamente utilizados, pero también hay algunos tubos de acero cuadrados, rectangulares, semicirculares, hexagonales, triangulares equiláteros, octogonales y de otras formas especiales. Para tuberías de acero bajo presión de fluido, se requiere una prueba hidráulica para verificar su resistencia a la presión y calidad. Está calificado si no se producen fugas, remojo o expansión bajo la presión especificada. Algunas tuberías de acero también deben engarzarse de acuerdo con los estándares o requisitos del comprador, prueba de abocardado, prueba de aplanamiento, etc.
MÉTODO DE PRODUCCIÓN
Los tubos de caldera son un tipo de tubos sin costura. El método de fabricación es el mismo que el de la tubería sin costura, pero existen requisitos estrictos sobre el tipo de acero utilizado en la fabricación de la tubería de acero. Según la temperatura de uso, se divide en dos tipos: tubo de caldera general y tubo de caldera de alta presión.
SOLICITUD
①General boiler tubes are mainly used to manufacture water wall tubes, boiling water tubes, superheated steam tubes, superheated steam tubes for locomotive boilers, large and small smoke tubes and arch brick tubes, etc.
②High-pressure boiler tubes are mainly used to manufacture superheater tubes, reheater tubes, gas guide tubes, main steam tubes, etc. of high-pressure and ultra-high pressure boilers. The supply and demand trend of the high-pressure boiler tube industry is generally stable, but the supply and demand situation of each specific sub-sector will be further differentiated. Industry insiders pointed out that the most critical link is the use and promotion of new energy-saving heat preservation 20g high-pressure boiler tube equipment.
New energy-saving 20g high-pressure boiler tube products are gradually increasing in the market, such as green environmental protection coatings, energy-saving and water-saving sanitary products, environmental protection stone, environmental protection external cement foam insulation board, etc. Energy-saving and environmental protection products have a broad market in the 20g high-pressure boiler tube industry The mid-term outlook is promising.
Los tubos de caldera se dividen en dos categorías:
GB/T3087-2018 medium and low pressure boiler tubes,Tubos de caldera de media y baja presión GB/T3087-2018,
Tubos de caldera de alta presión GB/T5310-2018,
Fórmula del peso del tubo de la caldera: [(diámetro exterior-espesor de la pared)*espesor de la pared]*0,02466=kg/m (peso por metro).
GRADO DE ACERO
(1) The steel grades of high-quality carbon structural steel are 20G, 20MnG, and 25MnG.(1) Los grados de acero del acero estructural al carbono de alta calidad son 20G, 20MnG y 25MnG.
