Galvanized Bread Tube Manufacturer, Bread Tube Production Factory, offering a complete range of sizes for sales of annealed black drawn tubes, welded black drawn tubes, black drawn black drawn tubes, thick-walled black drawn tubes, thin-walled black drawn tubes, black drawn tubes, large-diameter black drawn tubes, etc. Black drawn tubes are the ones commonly referred to as fan-shaped pipes. Black drawn tubes come in two types: 90-degree angle black drawn tubes and 45-degree angle black drawn tubes, and are now categorized as special-shaped tubes. Fan-shaped steel tubes

Black iron pipes can be categorized by use into electric vehicle black iron pipes, construction industry galvanized black iron pipes, machinery manufacturing galvanized black iron pipes, architectural decoration black iron pipes, shipbuilding galvanized black iron pipes, furniture black iron pipes, railing black iron pipes, power engineering black iron pipes, glass curtain wall black iron pipes, and more.

What's the difference between the two, also known as hot-dip galvanized and electro-galvanized? Hot-dip galvanized coatings are thicker, offering advantages such as even coating, strong adhesion, and long service life. Electro-galvanized products are more cost-effective, with a less smooth surface and significantly lower corrosion resistance compared to hot-dip galvanized. They feature hollow sections and are extensively used for piping that transports fluids, like oil, gas, water, and certain solid materials. Compared to solid steel like round bars, steel pipes are lighter in weight with the same bending and torsional strength, making them an economical cross-section material. They are widely used in the manufacturing of structural components and mechanical parts, such as oil drilling pipes, automotive drive shafts, bicycle frames, and construction applications.

① Elbows must be free from cracks and other defects. The surface should be free of hard spots. ② Any defects on the elbow tube are not allowed to be repaired by welding. The 10" size inspection is conducted by the company's relevant inspectors, based on the drawings and the relevant standards for pipe fittings, and in accordance with the tolerance requirements. 11 Surface treatment: The inner and outer surfaces of the elbow should be smooth, without any defects that would impair strength or appearance, such as scars, scratches, or heavy scaling. After defects are found, they should be ground and polished. The reduction in thickness at the grinding area should not be less than 935% of the original wall thickness. The grinding area should be smooth and the defect should be confirmed to be cleared by using a dye penetrant or magnetic particle inspection. After the elbow has been heat treated, by personnel holding relevant qualification certificates from the company, the elbow is inspected according to standard requirements for magnetic particle and ultrasonic testing, with results reaching Grade I qualification. The elbows are marked using a template spray or low-stress impression, and the standard requirements are clearly marked in order on the outer surface.
