We Offer Best Quality Galvanised Iron Tubes Galvanized steel pipes, manufactured by N.S. Trading Co., are covered by a layer of zinc .Galvanized steel pipes and tubes are mostly used in structural applications. Galvanized steel pipes and tubes are available in various size and shapes based on the customer's requirements. Pipes and tubing made of galvanized steel has long been one of the most used building materials in the world. For decades, designers, builders and consumers seeking long-term structural performance in the harshest of outdoor applications have turned to zinc-coated steel pipes. Zinc-coated galvanized steel pipes and tube resist the attack of wind, water and road salts. Product Features & Applications Galvanized Steel are those steel that has been covered with a layer of zinc metal. During galvanizing, steel is immersed in a molten zinc bath, ensuring a tough, uniform barrier coating. Zinc's natural corrosion resistance provides long-term protection, even in outdoor environments. Apart from preventing water corrosion, it is equally effective in dry, indoor environments. Steel tubes that undergo the hot-dipped galvanized process. Pre-manufactured steel tubes dipped in molten zinc. Range includes products from 21-273 mm outer diameter. Used in underground piping, overground piping, power etc.

We Offer Best Quality Pre Galvanised Tubes This category of N.S. Trading Co. tubes is generally made out of MS Galvanised Sheets. There are many preventive coatings (natural & synthetic) which are applied either before or after the production of tubes. Product Features & Applications In the recent technological innovations and analysis by the experts, it has been proved that the N.S. Trading Co. tubes made by pre galvanized sheets are giving very good durability, stability, adherence as well as a longer sustainability without atmospheric corrosion. These technological phenomenon are adopted by the steel manufacturers for enhancing their market potential as well as the profitability as they have very optimum cost control parameters. Made from pre-galvanized sheets. PSeveral coatings applied before and after tube production. Tubes are tough, durable, light-weight and zinc coated from pre-galvanized sheets. Finds application in fencing, cabling and ducting, automotive (bus body) and greenhouse structures.

The purpose of this specification is to provide standards for pipe suitable for use in conveying gas, water, and oil in both the oil and natural gas industries. This specification covers welded steel line pipe. It includes plain-end, threaded-end, and belled-end pipe, as well as through-the-flow line (TFL) pipe and pipe with ends prepared for use with special couplings. Although the plain-end line pipe meeting the specification is primarily intended for field makeup by circumferential welding, the manufacturer will not assume responsibility for field welding. SL This International Standards specifies requirement for the manufacturing of two product specification levels (PSL 1 and PSL 2) of seamless and welded steel pipes for use in pipeline transportation systems in the petroleum and natural gas industries. This International Standard is not applicable to cast pipe. 5CT This International Standard specifies the technical delivery conditions for steel pipes (casing, tubing, plain-end casing liners and pup joints), coupling stock and accessories and establish requirement for two Product Specification Levels (PSL – 1 & PSL – 2). These steel pipes are use as casing or tubing for well in the petroleum and natural gas industries.

Seamless pipe as the name suggests is a pipe without a seam or a weld-joint in contrast to Seam or Welded pipe. In a Seam or Welded pipe, the seam or the weld-joint is the weaker part of the pipe limiting the strength of the pipe to the strength of the weld-joint. Whereas the seamless pipe does not have any such joint and thus has uniform structure & strength all over the pipe body. Thus the seamless pipe can withstand higher pressure, higher temperature, higher mechanical stress & corrosive atmosphere and find wide applications in Oil & Gas, Refinery, Petrochemical, Chemical, Fertilizer, Power, Automotive, Bearing, Mechanical & Structural applications. N.S. Trading Co. is a leading international supplier of seamless pipes and tubes of all grades and dimensions with more than 10 years of product and business expertise. In our warehouse, we stock seamless pipes up to 24'' in the high and low-temperature range. The pipes are according to ASTM and API in the complete schedule series. Thick wall XXS is not missing in our warehouse. In addition we keep seamless pipes for structural application with high yield strength up to 1.000 ksi on stock. Through our international network, we can also supply you from stock or new production for example with pipes according ASTM A 312, high temp austenitic pipes acc. ASTM B 407, or nickel alloys in acc. to ASTM B165 or B622.
