Alloy Steel Flange:
Alloy flange is mainly used in the special characteristics of piping and pipelines, mostly for high-temperature & high-pressure position. The common materials are 12Cr1MoV, 15CrMo, P91, P22, 10CrMo910, etc.

2.Application & Type:
Application | Water works, Shipbuilding industry, Petrochemical & Gas industry, Power industry, Valve industry |
| and general pipes connecting projects etc. |
Type:
1) Weld neck flange(WN)
1, Preferred for high-pressure, subzero or elevated temperature
2, Hub is tapered and bored to match pipe's inside diameter so flow is not restricted, preventing turbulence and reducing erosion
3, Easily radiographed and provides excellent stress distribution
2) Blind Flange (BL)
1, Used to close ends of piping
2, Has no bore
3, Permits access to sealed lines
3) Lap Joint Flange (LJ)
1, Used where bolt alignment or access for cleaning is required
2, Similar to slip-on flange when used with lap joint stub end
3, Radius at intersection of flange face and bore to match lap joint stub end
4) Slip On Flange(SO)
1, Not normally used in high-stress applications due to low hub and weld attachment
2, Silps over outside of pipe
3, Inside of flange welded at hub and end of pipe
5) Socket Welding Flange (SW)
1, For small-diameter chemical processes, hydraulic and stream distribution lines
2, Similar to slip-on flange
3, Counter bore matches pipe bore, allowing unrestricted flow
4, Counter bore from hub side fits pipe's outer diameter - can insert pipe in socket with fillet weld at hub
6)Thread Flange (TH)
1, Used where welding would would be hazardous
2, Designed for low-pressure and non-cyclic applications
3, Bore is threaded to match pipe thread
4, Tapered to seal pipe and flanges
7)Other flanges
Orifice, Expander, Reducing, Lightweight, Studding Outlets, Long Weld Necks,Metric, Navy Drawings
3.Certificate & Inspection:
ISO9001:2008, SGS, BV, API etc.
Quality Control System-Well Equipments and Machinery-Well Workers and Engineers
4.QA & DOC:
Product Certificate, Chemical Composition Report, Mechanical Properties Report, UT Report, Heat Treatment Report, Dimensions Check Report.
