Selection and installation
From Pipe Selection to Installation Guidance
A large-diameter pipeline is more than a pipe specification. Shunfang supports customers with technical consultation, product selection and installation guidance to help align the piping system with project requirements. Share your application, diameter, pressure or ring-stiffness requirement, quantity, drawings and delivery schedule; our team will review the information and recommend an appropriate solution.

Four review themes
Turn project inputs into an engineering conversation.
The ten enquiry fields are grouped into four practical themes. Each image supports the information beside it instead of turning the page into a gallery.
Application & site context
Project location, conveyed medium, route conditions and installation environment establish the engineering context.
Dimensions & performance
Diameter basis, pipe length, pressure or ring stiffness determine the correct product review path.
Connection & standards
Jointing preference, transitions and applicable standards shape the complete pipeline system.
Drawings & delivery plan
Drawings, quantities and target dates help coordinate manufacturing, inspection and shipment.
Engineering FAQ
Preparing a productive technical review
Why are pressure and ring stiffness separate fields?
Pressure systems and gravity-flow structured-wall systems follow different selection inputs. Pressure requirements apply to pressure pipe; ring stiffness and burial conditions guide structured-wall pipe review.
Can Shunfang review an early-stage project?
Yes. Send the information currently available and identify what is still preliminary. The team can outline the next technical questions without treating website content as a final design.
When should on-site production be discussed?
For pipe projects above 3 metres in diameter, discuss site area, logistics, schedule and local conditions early so feasibility can be assessed.
Visual planning guide
Coordinate the whole installation scenario
Review the pipe system together with project engineering, connection, installation and operating conditions.
Electrofusion-band joint reference
A DN1200 electrofusion-band connection illustrates joint preparation for structured-wall pipe. Installation parameters follow the selected product and approved project procedure.
Pullback installation planning
Long pipe strings, pulling forces, route geometry, equipment and connection sequence should be reviewed before trenchless installation.
Marine intake and outfall coordination
Marine projects require project-specific review of alignment, joining, towing, sinking, ballast and diffuser requirements.
Laboratory and quality control
Every batch leaves a record.
Company-owned laboratory equipment and a three-step inspection routine from the corporate presentation: material arrival, in-process sampling and written release.
Laboratory equipment
Universal strength tester
Tensile and mechanical checks on pipe materials and joint zones.
Laboratory equipment
Ring stiffness tester
Stiffness verification for buried structured-wall pipe duty.
Laboratory equipment
Static hydraulic test station
Long-duration pressure holding for pressure-pipe batches.
Laboratory equipment
In-house samples and reports
Batch samples with written records before shipment release.
Incoming material inspection
Resin and reinforcement batches are checked against quality indicators on arrival; incoming quantity, test quantity and results are logged.
In-process sampling
Production batches are sampled during manufacturing, including weld-zone tensile checks across diameter groups.
Pre-shipment release records
Each batch ships with written inspection records and approval signatures from the quality team.
Delivery proof · Indonesia
DN2400 seawater circulation for aquaculture.
Two parallel DN2400 seawater-circulation lines, each 600 m long and rated at 1.0 MPa, delivered for an Indonesian aquaculture project. The delivery scope covered high-salinity and silty-seabed conditions, reinforced PE pipe selection, onshore prefabrication, offshore float-out and submerged installation.
