Flange
1. Application:
For seal or connect of pipe/tub-e lines
2. Material:
304,304L,316,316L,carbon steel or other material on request
3. Standard:
ANSI,DIN,JIS,BS,EN1092-1
4. Size:
DN15 (1/2") to DN5000 (200")
5. Type:
Threaded Flanges, Socket Welding Flanges, Blind Flanges, Other Flanges
Â
Types' Specification
Welding neck
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
Slip-on
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
Lap joint
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
Threaded
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
Socket welding
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
Blind
1, Used to close ends of piping
2, Has no bore
3, Permits access to sealed lines
Other flanges
Orifice, Expander, Reducing, Lightweight, Studding Outlets, Long Weld Necks,Metric, Navy Drawings, Customer Drawings

STABLE AT LOW SPEED
Closed-loop control pressure and flow, at low pressure and low flow operation performance is particularly outstanding, shoot rubber speed in less than 1 mm/sec without crawing,pluse,high stability. System according to the actual product process requirements, set arbitrary pressure and flow, avoid excess heat generation, the oil temperature relative to the traditional injection molding machines is stable. In addition, the pressure stability of the pressure and flow rate, high control accuracy and repeat precision.
MACHINE SERVICE LIFE LONGER AND CLEANER WORKING ENVIRONMENT
Less noise emissioins
The noise of th hydraulic system control within the scope of the national standard.
Low heat and cooling energy demand is low, more suitable for production environment with air conditioning.
Injection Molding Machine boot into the steady-state oil temperature rise of 8℃-10℃
