Bypass Pipe Plugs and Flow-Through Stoppers

Inflatable bypass plugs with central flow-through connections for temporary pipeline diversion and maintenance.

Product Overview

Inflatable bypass plugs with central flow-through connections for temporary pipeline diversion and maintenance. BTCOOPS / Wuxi Fenigal presents the range as a practical configurable product family for international project inquiries, with materials, ports, sizes and accessories selected against the application.

Bypass diameter should be sized from required flow, not just pipe diameter.

Typical Applications

· Sewer bypass

· Flow diversion

· Pipeline repair

· Temporary pumping

· Maintenance isolation

Data-use note: The table is a web-selection range assembled from Chinese supplier product pages and common China-market configurations. It is deliberately specific enough for product-page lead generation, but it is not a factory production guarantee. Final dimensions, pressure/load and materials are selected against the inquiry.

Construction & Material Platform

Reinforced rubber or rubber-coated fabric plug body with inflation connection; options include bypass tube, eyelets/restraint, long-body construction and project-specific packer/injection ports.

· Actual internal pipe diameter and condition

· Maximum backpressure / water head

· Required bypass flow if any

· Available insertion length and access point

· Inflation source, restraint and test method

Selection & Configuration Guide

For a useful quotation, the buyer should provide the following information. This also helps distinguish a standard web-reference model from a custom engineered version:

· Actual internal pipe diameter and condition

· Maximum backpressure / water head

· Required bypass flow if any

· Available insertion length and access point

· Inflation source, restraint and test method

Available Customization

· Capacity, overall dimensions and aspect ratio / geometry

· PVC, TPU, rubber or project-specific membrane platform as applicable

· Inlet, outlet, vent, bypass, inflation and drain connections

· Valve / flange / camlock materials and connection standards

· Colour, marking, OEM label and multilingual instructions

· Groundsheet, repair kit, hoses, control accessories, frames, straps or manifolds as applicable

· Packing method for courier, air freight, LCL or full-container shipment

Accessories & Optional Supply Scope

· Inflation hose

· Pressure controller / regulator

· Bypass hose

· Restraint points / tether

· Protective sleeve / repair kit

Packaging, Transport & Storage

Products are normally supplied deflated or empty, dried and folded to minimise shipping volume. Smaller units can be carton packed; medium and large units are typically packed in reinforced woven/PVC bags, pallets or export cases according to weight, fittings and destination. Metal fittings are separately protected against impact. Store dry, ventilated and away from sharp objects, heat sources and aggressive chemicals.

Commercial Guidance

Item	Web / Inquiry Guidance
MOQ	Typical project supply can start from 1 set for large/custom items; smaller standardized items may use multi-piece MOQ.
Sample / Trial	Where size allows, a sample or small trial order can be arranged before project batch production.
Typical Production Lead Time	Common custom flexible-fabric products: approximately 10–30 working days depending on size, quantity, material and accessories.
Warranty Positioning	Website wording should state a project warranty agreed in the quotation; avoid promising a fixed period for every material/application without project confirmation.
Export Terms	EXW / FOB / CIF and project logistics can be quoted according to destination and shipment size.

FAQ

How do I choose the plug size?

Use the actual internal pipe diameter and verify the product operating range, contact length and required backpressure.

Can a plug include bypass flow?

Yes. Flow-through plugs use a central bypass tube or port sized for the required temporary flow.

What pressure do inflatable plugs use?

It varies widely by construction. Chinese web examples range from about 0.05–0.06 MPa for simple small plugs to around 2.5 bar for reinforced sealing bags.

Can very large pipes be isolated?

Yes. Chinese suppliers advertise reinforced plugs for diameters extending to approximately 2,500 mm, subject to project design and restraint.
