Facilities

Material cutting and preparation

Plate, profile, tube and bar stock prepared for structures, supports, guards, piping components and machined parts. Preparation takes account of subsequent welding, machining and surface requirements.

Facilities

Laser centre: cutting, marking, cleaning and welding

Our in-house laser centre supports cutting from manufacturing data, component marking, surface cleaning and welding. These operations are coordinated with design, production preparation and subsequent assembly.

Facilities

Facilities

Surface preparation: abrasive and wet blasting

Before coating and during refurbishment, we prepare surfaces by abrasive blasting and wet abrasive blasting. Suitable processes remove contamination, corrosion products and existing layers according to component condition and the requirements of the subsequent finish. Mechanical, laser or electrochemical cleaning complements preparation as appropriate to the material.

Facilities

In-house wet painting and powder coating

Our in-house wet-painting and powder-coating facilities connect manufacturing with surface preparation and finishing. We provide surface protection for parts, weldments and structures according to the operating environment, appearance and assembly requirements.

Linear 4–20 mA scaling, pipe flow velocity and cylindrical volume.

Glossary

DN — nominal size

DN is a standardised size designation for a piping component, consisting of the letters DN and a number. That number is not an exact inside or outside diameter in millimetres. Actual dimensions depend on the product standard, material and wall thickness; connection details must also match.

Glossary

PN — nominal pressure designation

PN identifies a standardised pressure designation for piping components. Its number does not establish the permitted operating pressure at every temperature. Applicable limits depend on material, construction, the relevant standard and the product pressure–temperature rating; seals and connected components can impose additional restrictions.

Glossary

Kv / Cv — valve flow coefficient

Kv and Cv describe a valve’s flow capacity under defined reference conditions, using different unit conventions. Their numerical values are therefore not interchangeable. The required coefficient depends on fluid properties, flow and pressure conditions; a rated coefficient alone does not describe performance across the full control range.

Glossary

Absolute pressure

Absolute pressure uses an ideal vacuum as its reference rather than the surrounding atmosphere. This reference matters when describing vacuum conditions or calculating gas properties. The same numerical value of absolute and gauge pressure represents different physical conditions, so the pressure reference must always be clearly identified.

Glossary

Gauge pressure

Gauge pressure describes pressure relative to a reference, normally the surrounding atmosphere in a vented sensor. Positive values indicate pressure above that reference and negative values indicate pressure below it. A sealed-reference instrument behaves differently and must be assessed against the manufacturer’s specification.

Glossary

Differential pressure — Δp

Differential pressure is the pressure difference between two measurement points. It can indicate filter loading, support flow measurement across a primary element or measure level. A small difference may occur within a highly pressurised system, so differential range and permitted static pressure require separate consideration.

Glossary

4–20 mA — current loop

An analogue current loop represents a measured quantity as electrical current. With conventional linear scaling, 4 mA corresponds to the lower range value and 20 mA to the upper value. The live zero helps identify certain faults, but actual fault signalling depends on instrument configuration and receiving equipment.

Glossary

HART — instrument communication

HART enables digital communication with field instruments. In conventional HART over a current loop, digital data supplements the 4–20 mA signal with parameters, diagnostics and additional values. Access to that information also depends on compatible input cards, communication devices and instrument management tools.

Glossary

RTD — resistance temperature detector

An RTD measures temperature through changes in the electrical resistance of its sensing element; a platinum Pt100 is a common example. Lead wiring, measuring current, probe construction and contact with the process influence the result. The element designation alone does not establish the installed system’s accuracy or response time.

Glossary

TDR — guided wave radar

In TDR level measurement, an electromagnetic pulse travels along a probe and is partly reflected by the medium’s surface. The instrument derives distance from the return time. Probe selection and signal evaluation depend on medium properties, deposits, vessel geometry and whether level or interface measurement is required.

Glossary

P&ID — piping and instrumentation diagram

A P&ID shows functional relationships between equipment, piping, valves and instrumentation using symbols and identifiers. It aligns process, control and operating requirements. It is not a dimensionally accurate layout: lengths, installation positions and access clearances belong in other documents, which should use consistent equipment identifiers.

Glossary

I/O — inputs and outputs

I/O identifies the interfaces through which a control system receives information and sends commands. These include digital or analogue channels and data carried over industrial networks. A point count alone is insufficient: each signal needs an assigned function, electrical characteristics, address, diagnostics and any special requirements.

Glossary

PLC — programmable logic controller

A PLC is an industrial controller that evaluates inputs and operates machine or process outputs according to a program. Its behaviour depends on software, hardware configuration and connected communications. Ordinary process control and safety functions have different requirements and must be explicitly distinguished during design.

Glossary

HMI — human–machine interface

An HMI gives operators access to equipment status, permitted commands, settings and messages. It may be a local panel or a software application. A clear screen does not itself define control logic or user permissions; those relationships must be designed together with alarms, operating modes and fault responses.

Glossary

SCADA — supervisory control and data acquisition

SCADA supports supervision of a plant through data collection, visualisation, alarms and usually historical records. It brings together information from controllers and measurement points. Archiving, remote access and control functions are designed for the operation; the label SCADA does not establish a particular availability or security level.

Glossary

FAT — factory acceptance test

A FAT checks agreed equipment or system characteristics before dispatch, usually at the supplier’s premises. Testing follows an approved plan and acceptance criteria, sometimes using simulated signals or operating conditions. The report records results, deviations and outstanding items; its meaning is limited to the scope actually tested.

Glossary

SAT — site acceptance test

A SAT checks agreed characteristics of a supplied system after installation at its place of use. It can cover connections, communications, functions and interfaces with surrounding equipment under available conditions. Its scope follows the project acceptance plan; a successful FAT does not automatically verify the installed system’s local interfaces.

Glossary

WPS — welding procedure specification

A WPS describes how a weld is to be made, including essential conditions such as process, materials, joint preparation and welding parameters. It provides working instructions for repeatable execution. Its applicability depends on the procedure’s scope and qualification route; it does not itself qualify an individual welder.

Glossary

WPQR — welding procedure qualification record

A WPQR records trial welding conditions and the inspection and test results used to demonstrate a procedure’s capability within a defined range. It supports a corresponding WPS. Applicable rules determine the qualification range; a successful test on one joint does not qualify every material or thickness.

Glossary

NDT — non-destructive testing

NDT comprises methods used to examine selected properties or discontinuities in materials and joints without making them unfit for further use. Examples include visual, penetrant, magnetic particle, ultrasonic and radiographic examination. Each method has its own sensitivity and limitations; no indication is not universal proof of defect-free material.

Glossary

Type 3.1 inspection certificate — material certificate

An EN 10204 Type 3.1 document states the manufacturer’s conformity with the order and reports results of specific inspection. An authorised manufacturer’s representative, independent of the manufacturing department, validates it. This is not automatically third-party certification, and the document must be traceably connected to the material or product supplied.

Glossary

Calibration

Calibration establishes, under stated conditions, a relationship between reference values and instrument indications, including their associated uncertainties. It enables interpretation of a measurement result. Calibration does not itself adjust an instrument or automatically establish suitability for a particular process; any adjustment and subsequent verification must be distinguished clearly.

Glossary

Metrological traceability

Metrological traceability is a property of a measurement result that can be related to a stated reference through a documented, unbroken chain of calibrations, each contributing uncertainty. It is more than an instrument label. A traceable result may still have uncertainty too large for the intended decision or tolerance.

Glossary

WLL — working load limit

WLL identifies the maximum working load assigned to lifting equipment under stated conditions of use. It must not be confused with breaking load or proof load. Usable capacity depends on the particular equipment, lifting arrangement, sling angles, temperature and other conditions specified by its manufacturer.

Glossary

Cavitation

Cavitation occurs when local pressure in a flowing liquid falls below its vapour pressure and the resulting vapour bubbles collapse as pressure recovers. In a valve, it can cause noise, vibration and surface damage. Risk depends on the liquid, temperature, pressure conditions and flow path design.

Glossary

Flashing

Flashing occurs when a liquid experiences a pressure reduction that leaves a persistent vapour phase downstream of a restriction. Unlike cavitation, pressure does not recover sufficiently for the vapour to collapse. The resulting two-phase flow can substantially change velocities, capacity and erosion exposure in the valve and downstream piping.

Glossary

Thermowell

A thermowell provides a mechanical and pressure barrier between a temperature sensor and the process. Its dimensions, material and mounting affect strength and measurement response. Flow can induce vibration, so the design may require assessment of mechanical loading and vortex excitation as well as the temperature range.

Glossary

Measurement uncertainty

Measurement uncertainty characterises the spread of values attributable to a measured quantity using the available information. It is not the same as measurement error or display resolution. Contributions can arise from the instrument, method and conditions; comparison with a tolerance requires understanding how uncertainty was evaluated and expressed.

Technology

Level measurement and tank inventory

Level, volume, temperature and liquid interfaces answer different operating questions. A suitable system turns them into information that the plant can use.

Technology

Pressure, differential pressure and temperature

A reliable reading depends on the complete assembly: process tapping or thermowell, transmitter and a correctly configured control-system input.

Technology

Gas analysis and sample conditioning

The analyzer is one part of the solution. Sample location, transport, conditioning and the connection to plant operation determine whether the result is useful.

Technology
