Pipe Spools Fabrication

Prefabrication can be of many different types and undertaken at many different scales, from fabrication of small components and sub-assemblies through to large welded and bolted assemblies requiring significant logistical challenge to transport to site

The use of modular construction is directly influenced by the client¡¯s requirements for speed of construction, quality, added benefits of economy of scale, as well as single-point procurement.

Light gauge steel framing is an integral part of modular construction as it is strong, lightweight, durable, accurate, free from long-term movement and is well proven in a wide range of applications.

A Pre-engineered steel is basically a that is made up of steel.

Just as the name ¡°Pre-engineered¡± suggests, these s are engineered at a factory and are assembled at site.

Built-up sections are produced at the factory and is then transported to the original site and assembled. This concept is generally used to build Metro stations, industrial units, warehouses, etc.

Prefabricated steel s as the name itself sounds, is made of pre engineered steel. Fabrication is done in controlled environment inside the factory and then sent to client location for assembly.

Hastelloy B3 is a nickel-molybdenum alloy with profound resistance to stree-corrosion cracking, pitting, corrosion and thermal stability greater to that of alloy B2.

This nickel steel alloy has good resistance to heat affected and knife-line zone attack. This alloy also bears the brunt of formic, sulfuric, phosphoric, acetic acids and various other non-oxidizing media.

Hastelloy B3 suppliers and Hastelloy B3 manufacturers can be reached out to all over the country.

They have good creep and oxidation resistance. Strengthening of super alloys is performed by solid-solution hardening, work hardening, and precipitation hardening methods.

With the addition of nitrogen as a strengthening agent, the alloy can be dual certified as Alloy 317 (UNS S31700).

Alloy 317L is non-magnetic in the annealed condition.

It cannot be hardened by heat treatment;?however?the material will harden due to cold working.

Alloy 317L can be easily welded and processed by standard shop fabrication practices.?

The higher molybdenum content of Alloy 317L assures superior general and localized corrosion resistance in most media when compared with 304/304L and 316/316L stainless steels.

Environments that don¡¯t attack 304/304L stainless steel will normally not corrode 317L.

One exception, however, are strongly oxidizing acids such as nitric acid. Alloys that contain molybdenum generally do not perform as well in these environments.?

Alloy 317L has excellent corrosion resistance in a wide range of chemicals. It resists attack in sulfuric acid, acidic chlorine and phosphoric acid.

It was developed for enhanced creep resistance and for higher strength at temperatures above 1000¡ãF (537¡ãC).

Chromium, molybdenum, nickel and nitrogen all contribute to overall resistance to corrosion by various media

In most instances, the carbon content of the plate enables dual certification.

Chromium is the principal agent for conferring corrosion resistance in neutral or oxidizing environments.

Alloy 347 stainless steel plate cannot be hardened by heat treatment, only by cold working.

Chromium, molybdenum and nitrogen increase resistance to pitting corrosion. Nickel imparts the austenitic structure.

It can be easily welded and processed by standard shop fabrication practices.

?The low carbon content of Alloy 317L enables it to be welded without intergranular corrosion resulting from chromium carbide precipitation enabling it to be used in the as-welded condition.

Alloy 347 stainless steel plate exhibits good general corrosion resistance that is comparable to 304.

UNS S31254 is often referred to as a ¡°6% Moly¡± grade due to the molybdenum content.

Moly family has the ability to withstand high temperatures and maintain strength under volatile conditions.
