Product Overview

What It Is

The Dynaweld Split Frame (Clamshell) series is a portable pipe cold cutting and bevelling machine for on-site work. 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.

Key Features & Benefits

🔓

Split Frame — Fits Closed Loops

Separates into two halves to clamp onto in-line pipe and closed loops where the pipe ends cannot be reached. 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.

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.
