Steel pipe knowledge

In 2023, the Yuantai Derun-Tangshan production base commenced operations, boasting an annual capacity of 5 million tons.Zinc-Aluminium-Magnesium (ZAM) steel coils and ZAM steel pipes are the newly developed products, which represent a new generation of high -performance anti-corrosion materials.

Yuantai Derun uses advanced pickling and rust removal equipment to remove rust from square tubes

Tianjin Yuantai Derun square tubes: From light frames to heavy structures, curtain walls to solar projects. Full specs, high performance for diverse needs.

Tianjin Yuantai Derun: 20+ years in square tube production. Two modern bases in Tianjin & Tangshan, annual capacity >1 million tons, globally top-ranked.

Durable rolled and welded steel pipes for construction, structural, and industrial use. Available in custom diameters, thicknesses & lengths. Strong welds, corrosion-resistant.

Square rectangular tube have become one of the core materials of photovoltaic support structure due to their high quality mechanical properties, flexible size adaptation and weld connection methods.

Hot-dip galvanizing and cold-dip galvanizing are both methods of applying zinc to steel to prevent corrosion, but they vary greatly in process, durability, and cost.

The processing of welded steel pipes is a multi-step, multi-process manufacturing process involving key links such as material selection, forming, welding, heat treatment, and finishing.

Spiral welded pipe is a welded steel pipe produced by a continuous spiral forming process. It has the characteristics of light weight, high strength, corrosion resistance and long service life.

Spiral steel pipe, as an important building material, is widely used in construction, chemical, petroleum, natural gas and other industries.

There are two types of galvanized steel pipe: hot-dip galvanized pipes and cold-dip galvanized pipes. Relatively speaking, hot-dip galvanized pipe are less prone to rust than cold-dip galvanized pipe.

There are various methods to improve the surface quality of seamless steel pipe, and appropriate measures should be selected according to the situation to enhance the surface quality of seamless pipe.

GI galvanized pipe is widely used in many fields such as construction, water conservancy, electricity, and transportation due to its excellent corrosion resistance and long service life.

Structural pipes and fluid pipes are two major types of steel pipe applications. In practical project applications, we need to know the differences between them, can they be universal?
