1. Characteristics of D32 Steel PipesD32 steel pipe is a high-strength, corrosion-resistant steel pipe material commonly used in shipbuilding and marine engineering. Its main characteristics include:- Excellent strength and toughness: D32 steel pipe has high yield strength and tensile strength, enab

Medium-pressure seamless steel pipes play a crucial role in the steel industry. They are not only an indispensable basic material in many industrial fields, but also a core component in various equipment and engineering projects. Let's delve into the characteristics, applications, and manufacturing

The construction quality of steel pipe piles is crucial to the stability of the building. Therefore, attention must be paid to certain details during the construction process. The main precautions for steel pipe pile construction are as follows:1. Before construction, surveying and setting out must

1. For stainless steel pipe fittings, the arc should be started using the back-welding method, and the arc should be terminated using the method of creating a full arc crater. The arc starting process should be completed within the slope; arcing and starting should not be done on the surface of the

Hot-rolled steel seamless pipes are the most common format successfully used in all national economic sectors. These products are known for the greatest reliability, especially for laying communications for various purposes. Most often, a seamless hot-deformed steel pipe GOST 8732-78 is used in the

GOST 8734-75 defines the dimensional and technical requirements for cold-formed seamless steel pipes, covering products with an outer diameter from 1 mm to 200 mm and a wall thickness from 0.2 mm to 22 mm.The cold-forming process provides high-dimensional precision, an improved surface finish, and e

The process begins with pretreatment of the base pipe: grinding the steel pipe (advantages: automatic spraying ensures uniform coating on both inner and outer walls, good leveling, meeting CJ/T120-2008 and GB/T5135.20-2010 standards); preheating the ground steel pipe in an electric oven to 230°C~250

The materials used in the anti-corrosion processing of spiral welded steel pipes play a decisive role in the quality of the anti-corrosion steel pipes. During the anti-corrosion process, the raw materials must be strictly tested, as different anti-corrosion processes require different anti-corrosion

First, grinding is essential. The galvanized layer at the weld joint must be ground off; otherwise, bubbles, pinholes, and false welds will occur. It will also make the weld brittle and reduce its rigidity.Second, the welding characteristics of galvanized steel pipes. Galvanized steel pipes are gene

First, Steel Bend Processing1. Die Forging. For socket weld and threaded tees, crosses, elbows, and other small steel pipe fittings with more complex shapes, die forging should be used. The die forging blank should be a rolled profile, such as bar stock, thick-walled steel pipe, or plate. When using
