In applications where higher working pressures are a prerequisite, the use of seamless pipes is justified. Although stronger than welded pipe, the cost is much higher. In addition, in welded products, there is a greater risk of intergranular corrosion in the heat-affected weld zone. The obvious difference between alloy steel welded pipe and seamless product is the transverse seam along the length of the pipe

Cold drawn and cold rolled tube types are available. There are seamless tubes, welded tubes, ERW tubes and fabricated tubes. Seamless pipe is made from a single piece of material, whereas ASTM A333 Grade 6 Welded Pipe Specification requires it to be welded from strip or sheet of the same material grade.

Alloy steel is steel that is alloyed with a variety of elements in total amounts between 1.0% and 50% by weight to improve its mechanical properties. Alloy steels are broken down into two groups: low alloy steels and high alloy steels. The difference between the two is disputed. Smith and Hashemi define the difference at 4.0%, while Degarmo, et al., define it at 8.0%.[1][2] Most commonly, the phrase “alloy steel” refers to low-alloy steels.

The ASTM A320 specification, originally approved in 1948, covers alloy steel and stainless steel bolting materials for low temperature service.

There are different types of fittings such as bends, tees, crosses, reducers, caps and the WPHY 52 Elbow.In sour service wells, when hydrogen sulphide gas reacts with water, the hydrogen molecule gets deposited either on the pipes or fittings.

The heat treatment could be heat treated according to any of the WPHY 52 specification by either tempering, normalizing, quenching or stress relieving.A860 refers to the high quality of the fittings.

Alloy pipe is a higher percentage of tubular alloying elements such as molybdenum (Mo), chromium (Cr), nickel, etc. than standard carbon steel pipe. In fact, ASTM A335 covers “low alloy” steel pipes, that is, having less than 5% total alloying elements. The addition of higher percentages of alloying elements such as nickel and chromium converts the steel into higher alloys such as stainless steel, duplex stainless steel, up to superalloyed materials such as Inconel, Hastelloy, Monel, etc.

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.

Which means that one has to know if the alloy steel flange material is critical to achieving good weld integrity and the need for proper filler metal selection.High heat resistance steel grades are generally known as Chromium Molybdenum Steel.

The Alloy Steel Weld Neck Flange has a welded neck onto it that holds larger pipes in place for easy welding and installation.

ASTM A860 MSS SP 75 WPHY 52 Fittings are generally used at High Pressure requirements.Our wide range of Grade WPHY 52 Pipe Fittings includes: WPHY Gr 52 Bend, Elbow WPHY 52 in 45/90 degree, WPHY Grade 52 Tees, Carbon Steel WPHY 52 U Bend, MSS SP75 WPHY Gr 52 Stubends & ASTM A860 WPHY Grade 52 Pipe Nipple.

Alloy Steel AISI 4140 bar stock or forging stock to produce B7 headed and non-headed bolts. A193 Grade B7 is the most commonly used Bolt specification coupled with A194 Grade 2H Nuts for Bolting Carbon Steel pipeline. A193 B7 bolting is available in metric sizes from M6 to M180 and imperial sizes from 1/4 to 7 inches, in diameter.

The rim has numerous holes drilled into it that enables the flanged to be attached to a bolted flange. This design is far better because of the structural valve.

A335 pipe is highly resistant to rupture at high temperature and pressure. Chromium molybdenum tubes with resistance to hydrogen cracking and sulfide stress corrosion cracking are superior to carbon tubes.

Chromium molybdenum has a better strength-to-weight ratio than steel, which enables designers to use thinner walled tubing or smaller diameter tubing to reduce overall weight.

It is almost the same as AISI 4130 chrome-molybdenum alloy steel, but with a slightly higher carbon content. Compared to AISI/ASTM 4130 alloy steel, AISI 4140 steel has a higher carbon content, which provides higher strength and heat treating capability, but also has limited weldability.

While chromium is an important alloying agent in a335 P91 piping, it is known to prevent corrosion and has a high resistance to oxidation at high temperatures. Since these pipes are surface treated or coated, they are also protected against corrosion. Surface coating can be accomplished by various techniques such as passivation, phosphating, oil immersion, varnishing and shot peening.
