  • Seamless Steel Pipe

    Seamless pipe Including:Carbon Steel PipeSeamless Line PipeBoilers TubesStructural Steel PipePrecision Steel PipeAlloy Steel PipeNickel Alloy Pipe

    According to the production method, the seamless pipe is divided into a hot rolled pipe, a cold rolled pipe, a cold drawn pipe, an extruded pipe, a top pipe etc. 

    According to the shape of the section, the seamless steel pipe is divided into two types: a circular shape and an irregular shape, and the shaped pipe has a square shape, an elliptical shape and the like. 

    The maximum diameter is 650mm and the minimum diameter is 0.3mm. 

    Seamless steel pipe is mainly used as petroleum geological drilling pipe, cracking pipe for petrochemical industry, boiler pipe, bearing pipe and high-precision structural steel pipe for automobile, tractor and aviation.

About the welding technology of steel pipes

Welding heat affected zone Welded joint is composed offusion zone, weld and heat affected zone. Welding heat affected zone:HAZ​ (heat affected zone for short) is the area where themicrostructure and properties of solid base metal on both sides ofthe weld change significantly under the action of welding thermalcycle, which is called welding heat affected zone.

    Preparations for purchasing large-diameter straight seam steel pipes

    The purchase of large-diameter straight seam steel pipes should be communicated in advance. Before purchasing steel pipes, the pre-designed specifications, lengths, materials, wall thicknesses, welding standards and welding seam requirements should be followed. These should be communicated well before purchasing.

Notice

Dear Customer:
Hope this email finds you well.
The outbreak of COVID-19 has brought much inconvenience to the majority of foreign importers purchasing products from China. Since they are unable to make an on-the-spot investigation to Chinese suppliers and check the production of goods, which has led to "good opportunities" for some lawbreakers.
At present, there are some unscrupulous merchants and individuals in China. They make use of these opportunities and tempt you at ultra-low price 10% to 20% lower than the normal market price to purchase their products.
However then, they deliver the products by means of offering shoddy, replacing the material of products, reducing the number of goods, etc. to make huge profits, resulting to many customers suffering heavy losses. This has not only brought huge economic losses to customers, but also caused a very bad negative impact to China"s steel industry.
In order to prevent more foreign importers from being deceived, I solemnly suggest that importers carefully observe and choose Chinese suppliers, and do not blindly pursue abnormally low prices. If you are deceived unfortunately, please do not give up your legitimate rights and interests easily. You are supposed to file a lawsuit with the relevant legal authorities of the Chinese government through legal channels. China is a country with complete legal system, and the Chinese government always severely cracks down on such unscrupulous businesses.
