UKSPAR supplies a full range of fittings made of cast iron, carbon and stainless steel, polypropylene (PP) and PVC with prompt delivery throughout Ukraine.
Purpose and functionality
Sewerage fittings ensure efficient drainage of wastewater in residential, commercial and industrial facilities. Thanks to a wide range of nominal diameters (DN 50 – DN 1200), our equipment guarantees high throughput and absolute tightness of connections.Key tasks that fittings solve:
- Waterproofing and odor control: preventing the penetration of sewer gases into the premises.
- System configuration: branching, changing flow direction and transitioning between different pipe diameters.
- Reverse current protection: preventing flooding when highways overflow.
- Operational access: the possibility of auditing, cleaning and replacing individual areas.
- Mechanical filtration: retention of solid fractions to prevent clogging.
For rapid shutdown of the environment in emergency situations or during scheduled repairs, they are used latches (types Fig.Z101, Z104, Z202, Z203), which are characterized by low hydraulic resistance and high reliability.
Classification of sewer fittings
According to their functional purpose, fittings are divided into the following categories:
- Locking and protective: * Gate valves — optimal for thick and viscous media.
- Check valves — make it impossible to change the direction of flow.
- Revisions — special units for visual inspection and mechanical cleaning.
- Shaped parts (fittings): * Elbows, tees, reducers, crosses and couplings that form the geometry of the pipeline.
- Ventilation fittings: * Aeration plungers — prevent water seals from breaking, remove air bubbles, and equalize pressure in the system.
Production and quality control
The production of UKSPAR valves is based on strict adherence to the technological cycle: from precision design and casting to final mechanical processing.
- Anti-corrosion protection: applying epoxy or galvanic coating for operation in aggressive environments.
- Trial: Each product undergoes hydraulic tests for tightness according to class A.
- Resource: the service life is from 10 to 25 years old, depending on the working environment conditions and the selected material.
Compliance with standards (DSTU / EN)
The products comply with current regulatory requirements, which is critical for commissioning facilities:
- DSTU EN 12056: rules for calculating and designing gravity sewer systems.
- DSTU EN 1401-1 / 1451-1: requirements for PVC and polypropylene products.
- DSTU EN 877: standards for cast iron socketless systems (SML).
Each piece of equipment is marked with the following information: DN, PN, material grades and flow direction arrows. For the industrial sector, certificates of conformity and declarations are provided in accordance with the Technical Regulations for Pressure Equipment.
Selection recommendations
When selecting fittings, it is necessary to consider:
- Connection type: flared (for plastic), flanged (for high-pressure lines) or threaded.
- Chemical resistance: compliance of the housing material and seals (EPDM, NBR, Viton) with the composition of the wastewater.
- Installation conditions: quick access for service.
