The stainless steel seamless pipe Vickers hardness test is also an indentation test method for measuring very thin metal materials and surface layer hardness. It has the main advantages of Brinell and Rockwell methods, and overcomes their basic shortcomings, but it is not as simple as the Rockwell method. The Vickers method is rarely used in steel pipe standards.


Other terms :

1.A999/A999M: Each pipe shall be subjected to the nondestructive electric test or the hydrostatic test, the pipe of test to be used shall be at the option of the mfg, unless otherwise specified in the PO.
2. The Pipe lengths : Unless otherwise agreed upon, all size from NPS 1/8" TO AND INCLUDING nps 8 are available in a length up to 24ft with the permitted range of 15 to 24 ft. Short length are acceptable and the number and min, length shall be agreed upon between mfg and purchaser.
3. The finished pipe shall be reasonably straight and shall have workmanlike finish, Removal of imperfections by grinding is permitted, provided the W.T are not decreased to the less than the permitted in Section 9 of Specification A999/A999M
4. Butt Weld End: According to ANSI B 16.25
5. Pipe Marking: Specified in A999/999M, include "Logo+Standard+SIZE+Heat No.+Lot No.+H.T/E.T/U.T"
6. Packing: Each Pipe end is protected by Plastic cap. Then packed by Anti-rust steel strip, The outside of the bundle is plastic woven bag, or Plastic film.
8.MTC: BWSS Official Original MTC paper will be supplied for each order.


In addition, when the bending and torsional strength are the same, the weight is light, so it is also widely used in the manufacture of mechanical parts and engineering structures. Also used to produce a variety of conventional weapons, barrels, shells and so on. Steels that are open at both ends and have a hollow section, and whose length is larger than the circumference of the section, can be called steel pipes. When the length is small compared to the perimeter of the section, it can be called a pipe section or a tubular fitting, which are all in the category of pipe products.


Applications :
Foodstuff, gas, metallurgy, biology, electron, chemical, petroleum, boilers, nuclear, energy, construction field, ships building industry, war and electricity industry, boiler heat exchanger, machiner and hardware fields and medical equipment, fertilizer, etc
