The ISO 3183 Seamless pipe is formed by passing through a metal bar at an elevated temperature through a strong billet with a mandrel.

What is a Seamless Steel Pipe?

A steel pipe made of a single piece of metal with no cracks on its surface is called a seamless steel pipe, The seamless steel pipe has no welding or joints and is made of solid round billets. The seamless pipe is finished in sizes from 1/8 inch to 26 inch OD, with dimensional and wall thickness requirements.

Applicable for high-pressure applications such as Hydrocarbon Industries & Refineries, Oil & Gas Exploration & Drilling, Oil & Gas Transport and Air and Hydraulic cylinders, Bearings, Boilers, Automobiles.

MOST COMMON ISO 3183 SEAMLESS PIPES BY STANDARDS

Piping and covering, line pipes as per standard API 5L/ 5CT.

  • JIS Seamless steel pipes
  • GB Seamless steel pipes
  • ASMT Seamless steel pipes
  • DIN/EN seamless steel pipes

The hardness of ISO 3183 Seamless Pipes

Generally, by using chemical and electrolysis methods to process pickling pipeline anti-corrosion chemical pickling, the oxide scale, rust, old coatings can be extracted and sometimes used as sandblasting after reprocessing.

Though chemical cleaning can achieve surface cleanliness and roughness, the bolt pattern light and the air can be easily polluted

Specification of ISO 3183 Seamless Pipes are as follows:

  • Less In Diameter
  • Decent Solderability, high compression capability
  • Great performance steel tubing, metal fairly thick
  • Goods drew cold with high precision, proper consistency to the surface.
  • Steel Crossfield is more complicated.

Features of Seamless steel pipes:

First, thicker the solution’s wall thickness, the more cost-effective and wise it is, the thinner the wall thickness and its processing costs would appreciate sharply Second, from the process of the product, it determines its limitations, from the general seamless steel pipe with low precision: uneven wall thickness, flat brightness tube appearance, a fixed length of high cost, and pitting in the presence of black spots is challenging to get going;

Third, testing and plastic must be off-line. And it is in the higher pressure, high strength, its superiority represents the mechanical structure of wood. Chemical analysis of seamless steel pipes: chemical composition of the material for chemical analysis, chemical composition to meet the required specifications.

Seamless steel pipe pressure and the hydrostatic test is for pressure tube by into the hydrostatic test, which does not sustain the specified pressure value for not less than 5 seconds, the standard supply hydraulic pressure test is 2.45MPa pressure The pressure test is P = 0.5MPAa.

The corrosion check: industrial corrosion-resistant steel pipe according to standard guidelines or agreement between the corrosion test of the corrosion resistance of the steel pipe, no intergranular corrosion.
