FAQs

Electric Resistance Welding (ERW) pipe is manufactured by rolling metal and then welding it longitudinally across its length. Seamless pipe is manufactured from solid round billets, by extruding the metal to the desired length. Thus, ERW pipe has a welded joint in its cross-section, while seamless pipe does not have any joint in its cross-section through-out its length.
Seamless pipe is used for High-Pressure applications such as Hydrocarbon Industries & Refineries, Oil & Gas Exploration & Drilling, Oil & Gas Transportation and Air and Hydraulic cylinders, Bearings, Boilers, Automobiles etc. ERW pipe is used for Low or Medium Pressure level application.

MS ERW & GI pipes from 15 NB to 150 NB fall under the category of IS 1239 and pipes above 150 NB fall under the category of IS 3589.

GI (Galvanized Iron) pipes are another important class of pipes used in a variety of applications as well as industries. Galvanization is a process in which iron or steel is coated with a layer of zinc to protect them from corrosion or rusting. Pure iron is very ductile and contains no carbon. The metal zinc lasts long and helps to increase the life of iron or steel. Galvanized Iron pipes and steel are used in most of the structural applications and come with a layer of zinc to give 100% protection from rusting.

Maintaining quality in our products and services is our utmost priority. We assist every customer in all the quality assurance procedures. This can be achieved through:
a) Physical Stock Verification at the Warehouse
b) Third Party Inspection (TPI) by authorized vendors, to conduct relevant tests and provide certificates for the same
c) Original Test Certificates of purchased items are provided to the customers

Transportation cost usually comprises two aspects, Loading Charges and Freight Charges. The customers are free to bring their own commercial vehicles to carry the required items. Alternatively, they can also request us to arrange it for them.
We have an extensive network of transporters throughout the country to support any delivery. Both Full Loading and Part Loading facilities would be made available directly from the transporter.
FOR rates are shared on customer request. These rates are inclusive of the purchase price of the material, the loading charges and the freight cost up to the requested delivery site or the transporter godown as the case may be.

Tax rates are applicable as per government norms. Domestic purchases attracts an 18% GST rate.

The difference between Mild Steel and Carbon Steel is related to the amount of Carbon they contain. Mild Steel has about 0.16% -0.3% carbon, whereas Carbon Steel has up to 2% of it. This allows Carbon Steel to be more hardened and tempered.
Carbon steel is an alloy of steel where carbon is the fundamental constituent and no base level of other alloying components is specified. Alloy steels are alloyed with other metals or materials, in addition to carbon, to improve their properties. Some of these components are silicon, manganese, sulphur and phosphorous.

Pipes & tubes are basically hollow bars, the differentiation is mainly depending on its end use & its dimension designation.
Tubes are usually thin walled sections. Their wall thickness ranges from 0.3mm to 12.7 mm. The wall thickness is specified in Gauges as BWG/SWG. Pipes have range of wall thickness from 2mm to 65mm. Tubes can also be easily coiled but the thickness and rigidity of the pipes makes them harder to bend.
Tubes can be used to connect parts of machines such as Heat exchangers, condensers and as a result are subjected to both internal and external pressures. Pipes are generally used to connect large machines to other large machines and are generally not subjected to external pressures.

Pipes undergo rigorous testing to ensure that they are of the highest quality. They are done specifically to meet certain requirements. The mandatory tests are grouped as :-

• Non – Destructive
• Hydro Testing
• Ultrasonic test (UT)
• Eddy Current Test (ECT)
• Magnetic Particle Inspection (MPI)
• Positive Material Identification (PMI)

• Destructive
• Mechanical Testing for Tensile Strength
• Mechanical Testing for Impact
• Mechanical Testing for Flattening
• Mechanical Testing for Flaring
