The invention can be used for the production of wastewater pipes.

The pipe structure fabricated integrally in factory includes main water-supply pipes, drain-pipes, heating pipes and electrical pipes connected with the stable facilities correspondingly.

Refuse is collected from n refuse chutes (RC) through waste pipes (100) leading to transport pipes (110).

The gas exhaust pipes are spaced apart from each other, and the gas feed pipes are also spaced apart from each other.

The use of this arrangement further allows the placement of the coolant supply and drain pipes to match the positions of the pipework for conventional cast iron panels.

The snap-action of the latching mechanism signals the installer that waste pipes are properly coupled.

Industrial effluent pipe is normally extruded from polyethylene.

Further, the gas exhaust pipes are inserted in an electrolytic tank, in which a low-temperature electrolyte is contained.

This invention relates to an improved household drain plunger (10) for use with household drains of various shapes and sizes.

A holder portion (2) having a spherical inner space is fixed to one (1) of drain pipes to be connected.

Elimination and/or mitigation of fouling in a vapor transport systems, such as vent lines and scrubber feed lines may be accomplished using an antifouling additive.

System for monitoring the obstruction of pipes, in particular of discharge pipes and syphons, and to signal this situation to the exterior, if necessary also remotely.

The sack is constructed with liquid drains (14) for the drainage of liquid which is separated from the composting material.

In the brown gas generation system, a cooler is installed outside gas exhaust pipes, through which brown gas flows, and traps are mounted on the gas feed pipes.

Any connecting hose and lead-through in the bottom of the bodywork of the motor vehicle for ventilation of the gas-tight housing shall have a minimum clear opening of 450 mm2.
