This page describes common request types. Available processes, equipment, tolerances, inspection, documentation, and fulfillment are confirmed for each quote.
Overview
Connect pressure interfaces to service and evidence requirements.
An oil, gas, or petrochemical request should connect the controlled component to pressure class, medium, temperature, corrosion or sour-service requirements supplied by the buyer, gasket or seal geometry, material state, joining, test plan, inspection, and documentation. These inputs require review before any process or route is selected.
Pressure interfaces
Identify gasket faces, seal grooves, flanges, bores, threads, joints, cladding, coatings, and machining stock.
Test and evidence plan
Define test method, conditions, hold points, inspection, traceability, witness needs, and requested records.
Industry request review
Customer-specified codes, sour-service requirements, supplier qualifications, testing, inspection, documentation, routing, and timing are reviewed per request. No compliance is implied.
Quote inputs
Four inputs that start a useful oil and gas review.
Provide the controlled service and evidence requirements, including pressure interfaces and test acceptance.
- Service definition
- Component identity, revision, function, medium, pressure, temperature, corrosion context, quantity, and target timing.
- Material and process state
- Material specification, source, condition, sour-service restrictions, joining, cladding, coating, heat treatment, and prior repair.
- Pressure interfaces
- Datums, gasket faces, seal grooves, flanges, bores, threads, joints, corrosion allowance, machining stock, and masks.
- Test and records
- Test plan, medium, conditions, hold points, inspection method, acceptance, traceability, witness needs, and requested records.

Flanged spool, gasket, and bolting context
Define component function, medium, pressure, temperature, corrosion context, sour-service restrictions, and requirement authority.
- Medium and pressure context
- Temperature and corrosion context
- Code and requirement authority
Helpful request detail
Include the customer service-condition sheet and identify every governing code or material restriction by revision.
Requirements are reviewed before capability, routing, documentation, fulfillment, or timing is confirmed.
Request contexts
Common oil, gas, and petrochemical request contexts.
These examples organize the request without confirming code eligibility, process, testing, result, or fulfillment.
MRO adapters and replacement parts
MaintenanceLegacy or field hardware defined by as-found condition, service context, retained interfaces, permitted changes, and acceptance.
Valve and pump components
Flow controlBodies, bonnets, trims, casings, impellers, and rings defined by pressure interfaces, material, tests, and records.
Flanges, hubs, and headers
ConnectionsPressure connections defined by class, gasket or seal geometry, bolt pattern, face requirements, marking, and inspection.
Exchanger hardware
Thermal systemsTube sheets, baffles, covers, and headers defined by holes, flatness, interfaces, material state, and acceptance.
Quote review flow
From service conditions to an accepted request baseline.
A short review flow keeps pressure interfaces, material state, tests, inspection, and records connected.
- 01
Share the controlled request
Provide the current drawing, model, revision, oil, gas, and petrochemical context, quantity, and target timing.
- 02
Review requirements and authority
Identify governing documents, precedence, approved substitutions, restricted data, and customer-controlled decisions.
- 03
Map process and evidence needs
Connect material, geometry, interfaces, process history, finish, inspection, documentation, and packaging requirements.
- 04
Confirm the quoted baseline
Pearson confirms accepted scope, routing, records, timing, and open questions before work proceeds.
Request readiness
Make the oil and gas request easier to review.
Six checks keep service, pressure-interface, and evidence decisions visible before routing.
Design intent before assumptions

State service conditions.
Identify medium, pressure, temperature, corrosion context, sour-service restrictions, duty, and requirement authority.
- 02
Control pressure interfaces.
Define class, gasket face, seal groove, flange, bore, bolt pattern, datum, and finish requirements.
- 03
Include corrosion allowance.
Locate required allowance, minimum remaining sections, protected areas, and measurement and acceptance rules.
