Polished stainless steel pipes shall be subject to internal inspection and strict manual selection by the steel pipe quality inspector through metal detector (or hydrostatic test), and qualified products shall be packaged and delivered.

8The use of welded steel mesh in China is still in its infancy. At present, the use of welded steel mesh in China accounts for less than one of the total amount of steel reinforcement. In the early s, steel welded mesh was listed as a key implementation project by the science and Technology Commission and the Ministry of construction, and specifications and procedures were formulated.

Classification by production method

NKumamotoGalvanized pipe is a kind of light thin-walled steel pipe with hollow square section,Products Show also known as steel cold-formed profile. It is a section steel with square section shape and size,لويسفيل35crmo سميكة الجدار أنابيب الصلب غير الملحومةماركة cold bending and high-frequency welding. In addition to wall thickness thickening, the corner size and edge flatness of hot rolled extra thick wall galvanized pipe reach or even exceed the level of resistance welding cold formed galvanized pipe.

JgFrom the comparison of the monthly summary apparent consumption data information of galvanized pipe and the real estate sales data information from to this year they show the consistency of height width ratio, which not only shows a positive correlation in the overall new trend, but also significantly conforms to the fluctuation direction of the monthly development trend.

Spiral seam high-frequency welded steel pipe (sy- for general low-pressure fluid transportation takes hot-rolled steel strip coil as pipe blank and is often spiral formed at warm temperature. High frequency lap welding method is selected for welding spiral seam high-frequency welded steel pipe for general low-pressure fluid transportation.


Packaging: Welding nets are generally packaged in paper (mostly gray white, yellow, etc.), some similar to welding wire diameter welding nets, agriculture, construction,Products Show transportation, mining and other industries. Such as machine shields, animal fences, flower and tree fences, window fences, aisle fences, baskets and decorations.

vAt present, there is still a big gap in the production technology of C-section steel between China and foreign countries.

WFilling: welded pipe is welded by electric welding of hot-rolled strip steel, hot-dip galvanized products have been widely used in industry (such as chemical equipment, petroleum processing,Products Show marine exploration, metal structure,لويسفيل35crmo سميكة الجدار أنابيب الصلب غير الملحومةماركة power transportation, shipbuilding, etc.), agriculture (such as sprinkler irrigation, heating room), construction (such as water and gas transportation, wire casing, scaffold,Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd house, etc.), bridges, transportation, etc. because hot-dip galvanized products

pUWith the development of China&#;s infrastructure, the investment in infrastructure continues to grow; Implement the strategy of western development. Economic construction has entered a new stage, and the demand for welded steel mesh for capital construction such as power, transportation water conservancy, housing and municipal engineering will increase exponentially.

Seamless pipe is a long steel with hollow section and no joints around it. There are more than production plants under more than companies in more than countries producing seamless pipes, including more than plants under more than companies in countries.


There are several ways to clean galvanized pipes

Packaging strategywWelded steel pipe, also known as welded pipe, is a seamless steel pipe made of thick steel plate or hot-rolled strip by electric welding after coiling and forming, generally with a fixed length of m. Welded steel pipe has the advantages of simple production and processing process, high production efficiency, many types, and less investment in machinery and equipment projects, but the general compressive strength is less than that of seamless pipe.

MFunction of I-beam: where is I-beam mainly used?

In the production process the stainless glittering pipe is affected by the outside and product surface. Due to galvanizing, the corrosion protection is not corroded. This is the thickness of zinc, and the quality and strength of its coating depend on longevity.

uM The cold-rolled stainless steel pipe has the advantages of large yield coefficient, no expansion, bending and so on. In order to reach the health grade standard of stainless steel pipeline, the pipeline after cold rolling must undergo bright annealing, demagnetization pickling, calibration and other procedures.

The surface of hot-dip galvanized parts is bright and beautiful.
