ASTM A106 belongs to the American standard, which contains steel grade: Gr.A; Gr.B; Gr.C. ASTM A106 standard specification for seamless carbon steel pipe for high-remperature service.

Spiral steel pipe used as a bridge type of steel pipe welding, production should find the best welding method for it in order to improve the production efficiency of spiral steel pipe.

ASTM material standards are developed by the American Society for Materials and Testing, ASTM material standards can include the chemical, mechanical, physical and electrical properties of the material. These standards include both a description of test methods to be performed on building materials, and the size and shape that these materials are to take. Building materials like concrete can be required by local law to meet ASTM standards before being used in construction. Among ASTM A53 and ASTM A106 are widely used. ​

ASTM A335 / A335M - 11 Standard Specification for Seamless Ferritic Alloy Steel Pipe for High-Temperature Service

For the ASTM standard, different material with different steel grade,besides, their mechanical properties and chemical composition, metallurgical properties are all different.

It is said that China's welded pipe market was aggected by price increasing in early July, and transactions activity slightly improved along with the rising prices. Because of the price increasing which would affect by a number of order.

ASTM International is an organization that publishes documents and develops standards on a wide variety of materials and processes.

The specific features of carbon steel pipe and alloy steel pipe is listed below for you reference:

The seamless steel pipe is strictly manufactured according to the GB/t8162-87, cold rolled (cold drawn) pipe outer diameter of 5 ~ 200mm. The wall is 2.5 ~ 12mm thick. The outer diameter of hot rolled pipe is 32 ~ 630mm. Wall thickness 2.5 ~ 75mm.

GB/T 3091Welded steel pipe for low pressure liquid delivery (2015 standard version) has been approved and released by standardization administration of the People’s Republic of China. The new version put into effect from June 1st, 2016, and meanwhile, the old version of GB/T 3091-2008 became officially invalidated.

The seamless steel pipe is strictly manufactured according to the GB/t8162-87, cold rolled (cold drawn) pipe outer diameter of 5 ~ 200mm. The wall is 2.5 ~ 12mm thick. The outer diameter of hot rolled pipe is 32 ~ 630mm. Wall thickness 2.5 ~ 75mm.

"ERW Pipe" is a high-frequency straight seam resistance welding pipe, English Electric Resistance Welding, the abbreviation referred to as ERW, used to transport oil, natural gas and other vapor-liquid objects meet the high and low voltage requirements, currently the world conveying pipe It occupies a pivotal position in the field.

Are you looking for best and high quality stainless steel pipe for your plumbing project? Then it is the right time for you to learn the basics to make your decision making become easier. Since buying stainless steel pipe might confuse you at first, you need to ensure that you know how to determine the high quality grade of each item before you decide to purchase it.

Many people would prefer stainless steel pipes since they are easy to maintain, they are also resistant to oxidation and they don’t affect the metals which they come into contact with. It is known to be the most useful and sturdiest element in the industry. With that, it has gained good reputation for all the customers all over the world.

welded pipe,welded steel pipe,welded tube

welded steel pipe according to a certain classification method and application thereof can be divided into:precision hydraulic tubes, cold-drawn precision steel, precision cold-rolled steel pipe, high precision steel, precision brighttube. Different materials and models of longitudinal welded pipe in use with a different value and function, in a process ofprocessing and production, make its use in different areas and industries.

ERW steel pipe is manufactured by high frequency electric resistance (ERW) technology. ERW has many advantages, such as high production efficiency, low-cost, saving in material, and easy-to-automation. It is a kind of important welding technology which is widely used in various industrial sectors such as aviation, energy, electricity, automobile, light industry and so on.
