Product specification and description

347H stainless steel pipe is a grade of stainless steel produced according to the American ASTM standard, which belongs to austenitic stainless steel.

347H stainless steel pipe due to chromium Cr, nickel Ni, niobium Nb, its intergranular corrosion resistance and polysulfuric acid intergranular stress corrosion resistance is good, with high temperature strength and plasticity, good weldability, the steel has higher high temperature strength and high temperature oxidation resistance than 316, so it is often used as heat strength steel.

Inspection Of Steel Pipe
Inspection of steel pipes
Our inspection of steel pipes generally includes: inspection of geometric size and surface quality: inspection of chemical composition, mechanical properties, technological properties, inspection of high-low tissue: non-destructive testing: inspection of some special properties and length measurement and weighing.
(1) Check the geometric size of the steel pipe
The outer diameter, wall thickness, bending degree and length of the steel pipe are checked on the inspection table with external calipers, micrometers, bending degree and length winding.
Sometimes, the outer diameter, wall thickness and length are also continuously tested by automatic size detection devices (such as automatic diameter measurement, thickness measurement, length measurement devices). For OCTG steel pipe also need to check the thread parameters.
(2) Check the inner and outer surfaces of the steel pipe
We generally use visual inspection for internal and external surface inspection, and in addition to visual inspection, the internal surface is also inspected by reflection prism. Some special purpose steel pipes also require non-destructive testing, including eddy current, magnetic leakage, ultrasonic, magnetic particle testing, etc., to check the quality of the inner and outer surface of the steel pipe.
(3) Mechanical properties and process performance inspection
In order to verify that the mechanical properties of the steel pipe meet the requirements of the standard, we need to conduct mechanical properties inspection on the steel pipe sampling.
The test of mechanical properties mainly includes tensile strength, yield strength, elongation, impact work, etc. The process performance test mainly includes flattening test, flaring test, water pressure test, flange test, cold bending test, perforating test and so on. These inspection items are selected according to the different standards and the difference in the use of the steel pipe.
(4) Non-destructive inspection
Our non-destructive testing methods include: magnetic leakage testing, ultrasonic testing, eddy current and fluorescent magnetic particle testing, ultrasonic spectrum analysis testing, ultrasonic imaging testing and ultrasonic high temperature testing

Material introduction

Stainless steel, also known as inox or Corrosion Resistant (Stainless) Steel (CRES), is an alloy of iron that is resistant to rusting and corrosion.  It contains at least 10.5% chromium, usually nickel, and may also contain other elements, such as carbon, to obtain the desired properties.  Stainless steel's resistance to corrosion results from the chromium, which forms a passive film that can protect the material and self-heal in the presence of oxygen.


The alloy's properties, such as luster and resistance to corrosion, are useful in many applications.  Stainless steel can be rolled into sheets, plates, bars, wire, and tubing.  These can be used in cookware, cutlery, surgical instruments, major appliances, vehicles, construction material in large buildings, industrial equipment (e.g., in paper mills, chemical plants, water treatment), and storage tanks and tankers for chemicals and food products.


The biological cleanability of stainless steel is superior to both aluminium and copper, and comparable to glass.  Its cleanability, strength, and corrosion resistance have prompted the use of stainless steel in pharmaceutical and food processing plants.


Different types of stainless steel are labeled with an AISI three-digit number.  The ISO 15510 standard lists the chemical compositions of stainless steels of the specifications in existing ISO, ASTM, EN, JIS, and GB standards in a useful interchange table.
