Industrial Pipes, Valves, Fittings and Flanges

PVF stands for pipes, valves and fittings, and many buyers also include flanges. Wootz.work supplies valves, fittings and flanges as one package.

Start with the fluid, operating pressure, temperature, required flow control and isolation function, followed by the valve material, end connection and applicable standards. Ball valves are commonly selected for on/off isolation, globe valves for throttling, gate valves for isolation, check valves for backflow prevention and butterfly valves for large-bore lines. The appropriate model depends on the actual service conditions and its individual ratings.

Ball valves provide on/off isolation, while gate valves are designed primarily for isolation in larger lines. Globe valves support throttling and shut-off, check valves prevent reverse flow, and butterfly valves provide flow isolation in relatively compact, large-bore installations. Selecting between them depends on the process requirements, available space and operating conditions.

Available materials across the product range include carbon steel, stainless steel, alloy steel, duplex and super duplex stainless steel, nickel alloys, Alloy 20, SMO 254, titanium and cupro-nickel. Specific options vary by product family. The catalogues also list brass, bronze and plastic-composite non-ferrous fittings.

Buttweld fittings connect through welding at the pipe ends and include elbows, reducers, tees, crosses, caps and custom bends. Socket-weld fittings are used for welded connections in smaller-bore piping, while threaded fittings allow connections to be assembled using matching threads.

The appropriate type depends on pipe size, design requirements, pressure conditions and the applicable fitting standard.

Yes. Wootz.work's documented offering covers valves, pipe fittings and flanges, allowing buyers to coordinate these product categories through one sourcing partner. Share the required sizes, materials, pressure classes, end connections, standards and quantities so the proposed items can be assessed against the project specifications.

The valve catalogue includes metal-seated ball valves rated for temperatures up to 1,000°F in the specified product range. It also lists ball valves for steam and thermal-fluid applications, with model-specific operating limits. The appropriate selection depends on the operating temperature, pressure, materials and seat configuration; the highest temperature rating should not be assumed to apply to every valve.

The catalogues include materials such as 316 and 316L stainless steel, 904L stainless steel, duplex and super duplex grades, nickel alloys, Hastelloy, Monel, Alloy 20 and SMO 254. The appropriate material depends on the fluid chemistry, concentration, temperature and operating conditions.

Material selection should be confirmed for the specific service rather than based on a general corrosion-resistance label.

API 602 covers compact gate, globe and check valves from NPS 1/4 to 4. API 608 covers metal ball valves with flanged, threaded or butt-welding ends.

Forged socket weld and threaded fittings suit small-bore, high-pressure lines in 2000#, 3000# and 6000# classes. Buttweld fittings suit larger lines that need a fully welded, smooth-bore joint.

NACE MR0175 (also published as ISO 15156) sets requirements for materials that resist sulphide stress cracking in oilfield equipment. We supply selected valves and tube fittings to it when your order specifies it.

Duplex 2205, super duplex 2507, SMO 254, 904L, cupro-nickel and titanium are all in our range. Send us your service conditions and our engineers will confirm the grade.

Yes, our ball and butterfly valves carry ISO 5211 mounting pads for direct actuator mounting, and we supply CSA and UL certified solenoid valves.

Yes, we buy raw material directly from mills and supply test certificates from certified NABL labs with full traceability.
