When contractors and users select materials for piping systems, Stainless Steel Seamless Pipe manufacturers in India is often overlooked due to its price compared to other options, such as PVC, for applications such as wastewater and chemical transportation. But the many advantages of stainless steel pipe for industrial and commercial applications make it a material that provides value and returns on investment.
The interior walls of pipes made of other materials will tend to rust, be damaged by abrasion, or accumulate debris. But thanks to the corrosion-resistant properties of stainless steel, this is much less common. This gives stainless steel the edge in sanitary water supply or hospital applications.
When you use stainless steel tubing, you buy a long-life product that will last decades in your business. Stainless steel is low maintenance and is unlikely to need a replacement for many years due to its corrosion-resistant properties.
For the finished seamless pipe, some inspections should be carried out before leaving the factory, such as the chemical composition of the steel pipe product, the dimensional accuracy of the steel pipe product, the water pressure test, defect detection spectral and other aspects.
Similarly, when purchasing seamless steel pipe, the user of seamless pipe products should also make a simple acceptance of seamless pipe products, check the production standards of steel pipe grades, check the specifications of seamless pipes, measure the dimensional accuracy of Stainless Steel 304L Pipe suppliers in India and the number of steel pipes checks acceptance.
- Chemical composition: Requirements are introduced for the content of harmful chemical elements such as Sn, Sb, Bi, Pb and gases N, H, O, etc. To reduce non-metallic inclusions in the tube blank and improve its distribution, molten steel is often refined with refining equipment outside the furnace. Even the tube blank is remelted and refined in an electro-slag furnace.
- Dimensional accuracy and shape: The geometric dimensions of the seamless steel pipe mainly include the outer diameter, wall thickness, ovality, length, curvature, cutting slope, groove angle and blunt edge of the steel pipe. , and the size of the cross-section of the heterosexual steel pipe
- Surface quality: Common defects are: Cracks, Fine Lines, Inner Folds, Outer Folds, Curling, Inner Straights, Outer Straights, Delaminations, Scars, Pits, Convex Hulls, Pits (Pockets), Scratches (Scuffs), Inner Spiral, Outer Spiral, Line blue, concave correction, roll printing, etc. Among them are dangerous defects such as cracks, internal folds, external folds, rolling, separation, scarring, pitting, and convex hulls; concave and roll printing is general defects.
- Physical and chemical properties: Including room temperature mechanical properties and specific temperature mechanical properties (heat resistance properties and low-temperature properties) and corrosion resistance properties (such as oxidation resistance, water corrosion resistance, acid and alkali resistance, etc.) Generally, it depends on the chemical composition and structure of the steel, Properties and purity of the steel, heat treatment of the steel, etc.
- Process performance: Including the flaring, flattening, pressing, bending, ring pulling and welding properties of steel pipe
- Metallographic organization: Including low-rise and high-rise steel pipe.
- Special: requirements other than the standards presented when the user uses the steel pipe.
