Please make sure to contact us for more information on the pipe fitting products such as the ASTM A860 MSS SP 75 WPHY 52 Pipe Fittings and their pricing.

When the carbon content of the a333 gr 6 welded pipe chemistry is lower, the chance of cracking in the welded area is also lower. However, some manufacturers prefer seamless pipes over welded pipes. The reason behind this is that the performance of the a333 gr 6 seamless tube is almost 20% higher than the welded one in high pressure environments.

ASTM A182 Gr F11 class 2 pipe flange has low thermal conductivity and moderately low tensile strength and also has many other properties like great quality, toughness and many other points.

Forming operations such as bending and flanging, as well as fusion welding, are well suited for ASTM A335 p11 alloy steel pipe. The specified tests for alloy steel seamless pipes include flattening test, bending test, hardness test and longitudinal or transverse tensile test.

Alloy Steel F9 Threaded Flanges is 100% recyclable, where 50% of new steel is produced using re-softened scrap metal rendering it an Eco-friendly material. There are different classes to indicate the pressure capacities of the flanges. The AS A182 F9 RTJ Flanges are a special type of flanges because they come in two parts that have two rings that are welded to the pipe ends first and then the pipes are brought together by welding.

A182-F11 has high thermal strength (¦Äb¡Ý440MPa) and oxidation resistance at high temperature, and has certain resistance to hydrogen corrosion.

ASTM A194 2H Heavy Duty Hex Bolts are the core product and are in stock. HT PIPE is a leading supplier of ASTM A194 2H Heavy Duty Hex Nuts. These are heavy duty hex nut type bolts as directed by ASTM A-193 specification.

ASTM A182 Stainless Steel Flanges are manufactured per ASME B16.5 150#, 300#, 600#, 900#, 1500#, 2500#.

We use tested and qualified raw materials to improve the machinability of alloy tubes. These are processed through a metallization process that refines structural and material defects.

ASTM 182 is used for pressure systems, including flanges, fittings, and similar parts that conform to specified dimensions or dimensional standards such as ASME codes.

For A335 steel pipe, the addition of molybdenum (“Moly”) increases the strength and elastic limit of the steel, and enhances the wear resistance, impact quality and hardenability of the steel. It also improves softening resistance, makes chrome steel less brittle and prevents pitting corrosion. Chromium is also a key element in stainless steel alloys, preventing oxidation of the steel at high temperatures and improving the corrosion resistance of the steel. It improves the tensile, yield and hardness properties of low alloy pipes at room temperature.
