(1) Steel pipes of different diameters can be produced using strip steel of the same width, and steel pipes of large diameter can be produced from narrow strip steel.
(2) Under the same pressure conditions, the stress of the spiral welded seam is smaller than that of the straight seam, which is 75% to 90% of that of the straight seam welded pipe, so it can withstand greater pressure. Compared with the straight seam welded pipe of the same outer diameter, the wall thickness can be reduced by 10% to 25% under the same pressure.
(3) The size is accurate, the general diameter tolerance does not exceed 0.12%, the deflection is less than 1/2000, and the ovality is less than 1%. Generally, the sizing and straightening process can be omitted.
(4) Continuous production is possible. In theory, long steel pipes can be produced, with small head and tail loss, and can increase the metal utilization rate by 6% to 8%.
(5) The equipment is light in weight and low initial investment. It can be made into a trailer-type mobile unit to directly produce welded pipes at the construction site where the pipeline is laid.


Galvanized steel pipe tube is a type of steel that is coated with zinc for protection by an electroplating process. The galvanized layer is applied to cold rolled steel at low temperatures. Galvanizing is a well-known and effective method to add a protective layer to prevent the exposed steel from being corroded by natural elements. Zinc not only acts as a barrier between the environment and the steel, but it also decomposes first to protect the underlying steel and extend its service life. Zinc is generally represented by Z. Z is the abbreviation of English Zinc. Z120 means that the galvanizing content is 120 grams per square meter. The number after Z indicates the average coating content at three points on both sides of the galvanized steel in grams per square meter.

Description of application effect
Alloy steel is steel that is alloyed with a variety of elements in total amounts between 1.0% and 50% by weight to improve its mechanical properties. Alloy steels are broken down into two groups: low-alloy steels and high-alloy steels. The difference between the two is somewhat arbitrary: Smith and Hashemi define the difference at 4.0%, while Degarmo, et al., define it at 8.0%.Most commonly, the phrase "alloy steel" refers to low-alloy steels. Strictly speaking, every steel is an alloy, but not all steels are called "alloy steels". The simplest steels are iron (Fe) alloyed with carbon (C) (about 0.1% to 1%, depending on type). However, the term "alloy steel" is the standard term referring to steels with other alloying elements added deliberately in addition to the carbon. Common alloyants include manganese (the most common one), nickel, chromium, molybdenum, vanadium, silicon, and boron. Less common alloyants include aluminum, cobalt, copper, cerium, niobium, titanium, tungsten, tin, zinc, lead and zirconium.
Application
Hot dip galvanized steel pipe is widely used in construction, machinery, coal mine, chemical industry, electric power, railway vehicles, automobile industry, highway, bridge, container, sports facilities, agricultural machinery, petroleum machinery, prospecting machinery, greenhouse construction and other manufacturing industries.
