China New Product Low Price ASTM A106 Gr. B DIN 2440 2448 St35/37 Schx60 Seamless Carbon Steel Pipe
Short Description:
ASTM A335 is often called as chrome moly pipe because of the chemical contain of Molybdenum (Mo) and Chromium (Cr). Molybdenum increases the strength of steel and Chromium (or chrome) is the essential constituent of stainless steel. The composition chrome moly alloy steel pipe make it ideal for use in power plants, refineries, petrol chemical plants, and oil field services where fluids and gases are transported at extremely high temperatures and pressures.

Alloy Steel pipe are heat treated to achieve mechanical properties as per the desired alloying element. Below are some of the types of heat treatment.
Normalize Quench and Tempering.
Quench and Tempering.
Normalizing & Hardening.
Transverse/longitudinal: tension and flattening, hardness, bend tests- for material which has been heat-treated in batch furnaces, these tests shall be made on the 5% of the pipes from each heat lot number. For smaller lots, one pipe at a minimum has to be tested.
ASTM A335 Gr. P91 shall have a hardness of 250 HB / 265 HV (25 HRC).
Hydro testing: shall be applied to every length of pipe.
The non-destructive electric test is optional.In an effort to finest meet up with client’s requirements, all of our operations are strictly performed in line with our motto “High High quality, Competitive Rate, Fast Service” for China New Product Low Price ASTM A106 Gr.
