The split-frame design separates into two halves, so it installs directly onto in-line pipe and closed loops where the pipe ends are not accessible. It performs spark-free cold cutting and machined weld-prep bevelling — simultaneously — on carbon steel, stainless steel, and alloy pipe. Who Uses It Pipeline contractors, mechanical and piping fabricators, plant shutdown and turnaround teams, offshore and oilfield maintenance crews across the UAE, Qatar, Saudi Arabia, Kuwait and Oman. Essential where hot work is prohibited, where alloy pipe metallurgy must be protected, or where a precise machined bevel is required for weld prep. Where It Is Used Oil & gas pipeline tie-ins, refinery and petrochemical plant turnarounds, offshore platform piping, power plant boiler and header work, and process pipework fabrication across the GCC — from Dubai and Abu Dhabi to Doha, Ras Laffan, Riyadh, Dammam, Jubail, Kuwait and Muscat. ⚙️ The Dynaweld Advantage — Aviation-Grade Aluminium Unlike traditional heavy carbon-steel machines, the Dynaweld Split Frame series uses an aviation-grade aluminium alloy housing. This makes it significantly lighter — easier to install by fewer operators in difficult-to-reach locations — naturally corrosion resistant for offshore, marine, and humid oilfield environments, and it maintains a high strength-to-weight ratio so the machine stays rigid under cutting loads without the excessive mass of steel. 2 Drive System & Power Station Options Drive System Options Feature Electric (OCE) Pneumatic (OCP) Hydraulic (OCH) Power / Pressure 220-240V, 1 Phase 0.8–1.0 MPa 10 MPa Rated Pressure Capacity 2.0–2.4 KW 1500–3000 L/min 7.5 / 11 / 15 / 22 KW RPM 480 480 Adjustable Key Benefit High Performance Motor Explosion Proof / Safety Powerful Torque / PLC Control Hydraulic Power Station Selection Specification PLC Type Station Explosion-Proof Station Diesel Power Station Power Supply 7.5 KW 7.5 KW 22 HP (15 KW) Voltage 380V, 3PH, 5 Lines 380V, 3PH, 5 Lines N/A (Diesel Engine) Rated Pressure 10 MPa 10 MPa 10 MPa Rated Flow 0–36 L/min (Adjustable) 36 L/min 50 L/min Control PLC / Remote Manual / Remote Manual 3 Bevelling & Processing Capabilities Bevelling Types V-Type — standard weld prep.

Essential for tie-ins, repairs, and replacements on existing pipe systems that cannot be dismantled. 🔥 Spark-Free Cold Cutting Machines the pipe mechanically with no heat, flame, or sparks — intrinsically safe for hazardous and live-plant environments where hot work permits are restricted or prohibited. The required cutting method on most oil & gas and petrochemical sites across the GCC. ⚙️ Simultaneous Cut & Bevel Performs cutting and weld-prep bevelling in a single operation — saving critical time during plant shutdowns and turnarounds, and producing a machined, weld-ready bevel with no secondary grinding. 🪶 Lightweight Aluminium Housing Aviation-grade aluminium alloy — far lighter than steel machines, allowing installation by fewer operators in confined and elevated locations, with natural corrosion resistance for offshore and humid oilfield use. 🧊 No Heat-Affected Zone Cold cutting produces no HAZ — the pipe metallurgy is unchanged at the cut. Critical for stainless steel, duplex, and alloy pipe where heat distortion or metallurgical change would compromise the joint. 🛡️ Explosion-Proof Drive Available Pneumatic (OCP) drive runs on compressed air with no electrical components — inherently explosion-proof for ATEX/hazardous areas. An explosion-proof hydraulic power station is also available for live-plant pipe cutting. 6 Applications by Industry Industry Application Oil & Gas — Pipelines On-site pipe cutting, bevelling, and tie-in weld prep on pipeline construction and repair across ADNOC (UAE), Aramco (Saudi Arabia), QatarEnergy (Qatar), KOC (Kuwait) and PDO (Oman) — where spark-free cutting is mandatory Refinery & Petrochemical Pipe severing and weld prep during turnaround and shutdown maintenance at refineries and petrochemical complexes in Ruwais, Jubail, Ras Laffan, Dammam and across the GCC Offshore Platforms Pipe cutting on offshore topside and process piping — lightweight aluminium and explosion-proof pneumatic drive suit confined, elevated, and hazardous offshore locations in the Arabian Gulf Power Generation Boiler tube, header, and high-pressure pipe cutting and bevelling for power plant construction and maintenance across UAE, Saudi Arabia, Qatar and Oman Process & Fabrication Precision cold cutting and machined bevel prep for stainless, duplex, and alloy process pipework in fabrication shops where HAZ-free, weld-ready ends are required Nuclear & Critical Service Spark-free, HAZ-free pipe machining for critical service and high-integrity pipework where flame cutting is not permitted and machined weld prep is specified 7 Frequently Asked Questions What is a split frame cold cutting machine and how does it work?A split frame (clamshell) cold cutting machine clamps around a pipe and rotates a cutting/bevelling tool around it to sever and prepare the pipe end. Its split-frame design separates into two halves, so it installs onto in-line pipe and closed loops where the ends are not accessible. Cold cutting is spark-free — it machines the metal mechanically rather than using heat or flame — making it safe for hazardous areas, live plants, and alloy pipe where heat-affected zones must be avoided. Why choose cold cutting over flame or plasma cutting?Cold cutting is spark-free and produces no heat-affected zone (HAZ), so pipe metallurgy is unchanged at the cut — critical for stainless, duplex and alloy pipe. It is intrinsically safe for hazardous and live-plant environments where flame cutting is prohibited. It simultaneously cuts and bevels, producing a machined weld-ready bevel with no secondary grinding, and gives a precise, square, burr-free cut. These make it the required method on most GCC oil & gas and petrochemical pipe work. What pipe sizes can the Dynaweld machines cut?The range covers 18 models from DW-89 (25–89mm OD) to DW-1830 (1630–1830mm OD) — small bore instrument pipe up to large diameter mainline. Maximum wall thickness is up to 110mm with the heavy wall slide. Drive options are electric, pneumatic (explosion-proof) or hydraulic depending on model. Send us your pipe OD, wall thickness, material and site power supply for model selection. Are explosion-proof machines available for hazardous areas?Yes. The pneumatic (OCP) drive is explosion-proof and inherently safe for ATEX-classified areas, running on 0.8–1.0 MPa compressed air with no electrical components. An explosion-proof hydraulic power station is also available. Both are used for pipe cutting on live oil & gas plants and offshore platforms across the UAE, Qatar, Saudi Arabia and wider GCC.
