NLS sources MMA electrodes, MIG/MAG wire, and TIG filler rod to AWS A5 classifications, for carbon steel, stainless, and low-alloy welding on Saudi projects.

Safety Footwear

Safety footwear protects against impact, compression, puncture, and slip hazards on a construction or industrial site, rated by toe protection class and sole properties rather than picked as general workwear.

Torque Tools

Torque tools apply and measure rotational force to a precise value, torque wrenches, torque screwdrivers and torque multipliers, so a bolted connection reaches its specified clamp load rather than an operator's guess. NLS sources torque tools calibrated to ISO 6789 accuracy and calibration requirements, covering click, dial and electronic types for structural, mechanical and flange-joint bolting work.

Air Compressors

An air compressor pressurizes and stores compressed air to drive pneumatic tools, sandblasting and painting equipment, and shop or site air lines.

Abrasives & Consumables

Abrasive consumables, grinding and cutting discs, flap discs and sanding belts, are the wear items a power tool needs to cut, grind or finish a surface, used up on a predictable schedule rather than lasting the tool's life. NLS sources bonded abrasive discs and wheels manufactured to EN 12413 safety requirements, matched to material and machine speed.

Butterfly Valves

Butterfly valves use a rotating disc on a shaft through the center of the pipe bore to start, stop, or throttle flow with a quarter turn. NLS sources wafer and lug-style butterfly valves built to API 609, tested to BS EN 593, dimensioned to ASME B16.34, for HVAC, firewater, and utility water lines on Saudi hospital, aviation, and industrial projects.

Ball Valves

Ball valves use a rotating ball with a bore through its center to give tight, quarter-turn shutoff with minimal pressure drop, the standard choice for full-open or full-closed duty. NLS sources floating and trunnion-mounted ball valves built to API 608, and pipeline-grade units to API 6D, dimensioned to ASME B16.34, for process and pipeline service on Saudi industrial projects.

Plug Valves

Plug valves seal with a tapered or cylindrical plug that rotates a quarter turn inside a matching body seat, giving reliable shutoff on slurries and solids-bearing lines that would jam a ball or gate valve. NLS sources lubricated and non-lubricated (sleeved) plug valves built to API 599, dimensioned to ASME B16.34, for process and utility service on Saudi industrial projects.

Needle Valves

Needle valves use a tapered, pointed stem that threads down into a small precision seat, giving fine control over low-flow, high-pressure lines like instrument gauge connections and sample points. NLS sources forged steel and stainless needle valves dimensioned to ASME B16.34, rated by pressure class and instrumentation practice rather than a single dedicated standard, for Saudi process and utility instrumentation.

Pressure Safety & Relief Valves

Pressure safety and relief valves open automatically once system pressure crosses a set point, protecting piping, vessels, and equipment from overpressure damage. NLS sources flanged steel PSVs built to API 526, sized and selected per API 520 methodology, matched to ASME BPVC Section VIII vessel ratings where applicable, for process and utility protection on Saudi industrial projects.

Solenoid Valves

Solenoid valves open or close using an electric coil that pulls a plunger the instant power is applied or removed, giving instant on/off control from an electrical signal rather than a manual handle. NLS sources direct-acting and pilot-operated solenoid valves on NAMUR-standard actuator mounting (VDI/VDE 3845), with explosion-proof coil options built to IEC 60079, for Saudi process and utility automation.

Knife Gate Valves

Knife gate valves use a sharp-edged gate that slides straight through the flow path to cut through slurries, fibrous solids, and heavy suspensions that would jam a standard gate valve. NLS sources knife gate valves built to MSS SP-81, dimensioned to ASME B16.34, in wafer and lug body styles, for slurry, wastewater, and bulk material lines on Saudi industrial projects.

Strainers

Strainers catch debris and particulate in a pipeline before it reaches a pump, control valve, or instrument, using a perforated or mesh screen sized to the protection level a system needs. NLS sources Y-type, basket, and duplex strainers in bodies rated to ASME B16.34 pressure-temperature classes, mesh-sized per project spec, for pump and equipment protection on Saudi industrial lines.

MIG/TIG Welding Machines

MIG/MAG and TIG welding machines are process-specific power sources. MIG/MAG synchronizes wire feed speed with output voltage for continuous-wire welding; TIG delivers a stable, controlled arc for tungsten electrode welding, often needing AC output for aluminum. NLS sources MIG/MAG machines with synergic wire-feed control and TIG machines with AC/DC output and pulse capability, to IEC 60974-1, for Saudi fabrication.

Welding Electrodes

Welding electrodes are the coated consumable rods used in MMA (stick) welding, where the coating burns to shield the arc, adds alloying elements, and forms a slag layer that controls how the weld cools. NLS sources carbon steel electrodes to AWS A5.1 and ISO 2560, across rutile, basic (low-hydrogen), and cellulosic coating types, matched to the joint's position.

Filler Wires

Filler wire is the consumable fed into a MIG/MAG or TIG weld, solid spooled wire for MIG/MAG and straight-length rod for TIG, and both have to match the base metal's chemistry, not just its general grade. NLS sources carbon steel MIG wire to AWS A5.18, low-alloy wire to AWS A5.28, and TIG filler rod to ISO 636.

Plasma Cutting Equipment

Plasma cutting equipment uses an electrically ionized gas jet to cut electrically conductive metal, faster and with a narrower kerf than gas cutting on materials up to roughly 40mm thick. NLS sources manual and mechanized (CNC-ready) plasma cutting systems, torches, and consumables, to IEC 60974-1 and IEC 60974-7, for structural steel, plate, and pipe cutting on Saudi projects.

Gas Welding Equipment

Gas welding equipment, regulators, blowpipes, and hoses, controls and delivers oxygen and fuel gas (usually acetylene) for oxy-fuel welding, brazing, heating, and cutting, a process still used where power isn't available or a controllable flame suits the work better than an electric arc. NLS sources regulators to ISO 2503 and blowpipes/torches to ISO 5172, matched to gas type.

Welding Accessories

Welding accessories, ground clamps, torch nozzles and contact tips, chipping hammers, welding blankets and curtains, are the supporting hardware that keeps a welding operation running and its surroundings protected, distinct from the machine and filler metal itself. NLS sources ground clamps, torch consumable parts matched to machine brand, and fire-rated welding blankets for Saudi fabrication and site work.
