Steel pipes, fittings, flanges, press fitting systems, pumps and PV brackets.
Rubber-lined suspension band clamps: bandwidth 20 / 25 mm, thickness 1.2-2.5 mm, sizes 15-250 mm and larger, M8/M10 bolts, body W1 (carbon) / W4 (SS304) / W5 (SS316) with EPDM lining (PVC or silicone optional). The EPDM liner isolates the pipe from metal, absorbs vibration and water hammer, protects
Push-fit and press quick couplings: no welding, no threading - fast repair and installation of steel and stainless lines. No hot-work permits are needed - practical for fire-fighting, mining, emergency and temporary pipelines. Supplied a
Rigid and flexible grooved couplings for DN25-DN300 (larger sizes to DN1200 on request), rated 1.6-2.5 MPa, working temperature -40 to +120 degrees C. Rigid couplings lock pipe ends with no movement; flexible couplings allow controlled linear and angular displacement for thermal expansion, settlemen
Wafer, lug and flanged butterfly valves, centerline and double-eccentric, with EPDM, PTFE or metal seats - compact, lightweight quarter-turn valves that are the cost-effective choice for large-diameter water, HVAC and general service lines. Valves are supplied as part of the Spai one-stop piping pac
Self-acting check valves that prevent reverse flow and protect pumps, compressors and equipment from backflow damage: swing, dual-plate and piston designs, cast and forged bodies. Valves are supplied as part of the Spai one-stop piping package - flange drilling, weld-end schedules and face-to-face d
Wedge gate valves with outside-screw-and-yoke bolted bonnet for full-bore isolation - unobstructed flow, reliable sealing, low pressure drop in the open position. Cast and forged bodies to API 600, API 602 and API 603 designs. Valves are supplied as part of the Spai one-stop piping package - flange
Ball valves with floating or trunnion-mounted ball, one-piece, two-piece and three-piece bodies, flanged, threaded, butt-weld and grooved ends. Forged-steel high-pressure designs, metal-sealed high-temperature service to about 950 degrees C, cryogenic extended-bonnet versions for LNG, LO2 and LN2 at
Blind flanges close pipe ends and vessel nozzles, and are the standard blank for pressure testing and future extensions - no other flange type carries pressure on a flat face. ASME B16.5 Class 150 and 300 dimensions held in stock, Class 600 on request; raised face standard.
The full flange family from one supplier: weld neck (WN) for high-integrity joints; slip-on (SO) with two fillet welds as the economical general-service type; socket weld (SW) for small-bore high-pressure; threaded (TH) for no-welding maintenance; lap joint (LJ) with stub ends for rotating alignment
Hot induction and hot formed bends at 3D to 10D radius to GB/T 12459 (3D), SY/T 5257 and ASME B16.49, or to customer drawing. Compared with standard elbows (R=1.5D), long-radius bends give smoother flow and less pressure drop. Full-length induction bending is followed by solution treatment per grade
Long and short pattern lap joint stub ends to MSS SP-43 and ASME B16.9, used with lap joint flanges: the lapped end forms the sealing face while the flange rotates freely for easy bolt alignment and dismantling - allowing cost-efficient combinations such as carbon steel flange with stainless stub en
2:1 ellipsoidal butt-weld caps to ASME B16.9 and GB/T 12459, DN15-DN600. Sizes DN350 and above can be plate-formed and welded to reduce weight and cost; extended straight lengths (extended E) available for easier field welding. Standard raw material grades ASTM A403 TP304/304L, 316/316L; duplex 2205
