Packing and Marking

Packed in bundles, wrapped in plastic, and suitably protected for sea -worthy delivery or as requested.

Molybdenum (Moly) increases the strength of the steel and its elastic limit, enhance the steel resistance to wear, its impact qualities, and the hardenability. It also improves the resistance to softening, makes chromium steel less prone to embrittlement and prevents pitting.

Chromium, a key element also for stainless steel alloys, prevents steel oxidation at elevated temperatures and increases the resistance of steel to corrosion. It enhances the tensile, yield, and hardness properties of low-alloy pipes at room temperatures.

ASTM A106

ASTM A106 seamless pressure pipe (also known as ASME SA106 pipe) is commonly used in the construction of oil and gas refineries, power plants, petrochemical plants, boilers, and ships where the piping must transport fluids and gases that exhibit higher temperatures and pressure levels. All forged ASTM A106 GR. B Carbon Steel Seamless Pipes should be solution annealed according to the heat treatment section to restore the ferrite – austenite equilibrium. The weld metallurgy of ASME SA 106 GR. B Carbon Steel Welded Pipes, as with other ferrite – austenitic stainless steels, has a ferrite structure during solidification. And when the weld metal temperature of ASTM A106 GR. B Carbon Steel EFW Pipes is in the 2100 Degree F to 2640 Degree F (1150 Degree C to 1450 Degree C) range, it is possible for the HAZ to increase its ferrite content. It is the cooling of the high temp ferrite of ASME SA 106 GR. B Carbon Steel ERW Pipes that allows retransformation into austenite, yielding a ferrite – austenite weld structure. Cooling rates of ASTM A106 GR. B Carbon Steel Round Pipes are extremely important as getting the weld area too hot, or using too much weld energy, leads to cooling rates being too slow, allowing the formation of embrittling sigma phase in the heat affected zone. Conversely, if not enough weld energy is used in ASME SA 106 GR. B Carbon Steel Square Pipes, then the cooling rates are too fast, leading to too much ferrite in the weld metal and a fragile weld joint.

Note:-

The minimum wall thickness at any point shall not be more than 12.5% under the nominal wall thickness specified. Weight of any length shall not vary more than 10% over and 3.5% under that specified. NOTE — NPS 4 and smaller — weighed in lots. Larger sizes shall be weighed separately by length.
