F55/S32760 Stainless Steel Pipe Fittings Duplex steel butt welding seamless and welded
"zheheng steel" produces and supply Wrought Steel Butt-Welding F55/S32760 Stainless Steel Pipe Fittings., Non-standard pipe fittings are also produced according to customer requirements. The company strictly implements ASTM B16.9 / B16.5,ASTM A403 SH3408, SH3409, DIN2605, EN10253, BS1965, JISB2312 and other standards for production. The materials used are special steel materials such as F51/S31803/F53/S32750/F55/S32760/F59/S32520/F60/S32205/F904L/N08904
UNS S32760 is a super duplex stainless steel. Contains 0.75%
tungsten and copper, 25% chromium (austenitic / ferritic) steel.
The supplied PREn (in terms of pitting equivalent) of this alloy
is> 40.0, which ensures a high pitting resistance. Zeron 100 has
high mechanical strength, good ductility, and corrosion resistance
to the marine environment at atmospheric and sub-zero temperatures.
Good resistance to abrasion, corrosion and cavitation and can also
be used in the working environment of acidic medium. Mainly used in
oil and gas and hundred marine applications, usually used in
pressure vessels, choke valves, Christmas trees, flanges and piping
systems.

Inspection and Test Procedure
| 1.100% PMI,Spectro Chemical Aanlysis Test for Raw Material |
| 2.100% Dimension & Visual Examination |
| 3. Mechanical Properties Test Include Tension Test,Flaring Test (For Seamless tube/pipe)/ Flange Test (For Welded Pipe & Tube), Hardness Test ,Reversed Flattening Test |
| 4.100% Hydrostatic Test or 100% NON-DESTRUCTIVE Test (ET or UT) |
| 5.Radiographic Test for Welded Pipe (shall be accordance with specification,or shall be as agreed upon between the purchaser and vendor) |
| 6.Straightness Test (optional) |
| 7.Roughness Test (optional) |
| 8.Intergranular Corrosion Test(optional) |
| 9.Impact Test (optional) |
| 10.Grain Size Determinations (optional) |
| NOTES : ALL THE TESTS AND INSPECTION RESULT NEED TO BE SHOWED IN REPORTS ACCORDING TO STANDARD AND SPECIFICATION. |
Why choose us:
1. All pipe fittings are strictly implemented in accordance with
the standards, accept any third-party inspection, and return
service.
2. Before leaving the factory, 100% dimensional inspection, 100%
spectral test, mechanical and mechanical performance test,
pickling, pickling process are mainly aimed at the removal of
surface grease and harmful substances, complete surface passivation
to prevent oxidation. Some suppliers have not implemented ( Because
the surface is not visible to the naked eye after sandblasting)
annealing and solid solution (heat treatment), many goods on the
market are not heat-treated. When the pipe fittings are in some
cold or hot environments, the seam will slowly crack if it is not
heat-treated. This process is invisible to the naked eye, surface
sanding (many relatively inexpensive processes on the market),
bevel ends, etc.
3. Normally, the individual weight of our company's pipe fittings
is heavier than that on the market, (Ensure the back arc thickness)
to avoid the parts of the same wall thickness that cannot be seen
by the naked eye after the processing The pressure is guaranteed,
because many suppliers choose the material to the maximum limit in
order to minimize the cost.
