The crossover tee is used to raise the branch pipe elevation, cross over pipelines or obstacles, and is generally used in conjunction with planar tees and Z-type crossover pipes. The crossover tee is reinforced according to different pipe diameters.
Steel pipe buffering platform, pipe switching unit, traction machine, pipe threading machinery, high-pressure blasting machine, repair platform, transmission line, steel pipe preheating furnace, shot blasting machine main inspection platform, and the return transmission line for defective steel pipes, fast feed roller group, fast exit rollers, inspection platform, etc.
A simple processing technique involves cutting an opening on the pipe and directly welding a branch pipe; this is called a welded tee. Currently, this type of tee is only used in plumbing and large-diameter applications where processing is difficult.
In areas with high groundwater levels, to ensure that groundwater does not affect the normal operation of steam direct-buried pipelines, the outer protective layer should preferably use a sturdy, sealed steel pipe casing.
Prefabricated direct-buried insulated elbows are widely used in liquid and gas transportation pipeline networks, chemical pipeline insulation projects, petroleum, chemical industry, centralized heating networks, central air conditioning ventilation ducts, and municipal engineering pipeline bends.
Connection methods: clamp, flange, and threaded connection. For underground installation, bimetallic welding or non-destructive connection can be used.
Processing techniques: hot-dip plastic coating, high-pressure electrostatic spraying, rotational molding, plastic wrapping
Coated steel pipes are products that use PE (modified polyethylene) for hot-dip coating or EP (epoxy resin) for internal and external coating, featuring excellent corrosion resistance.
Since the emergence of polyurethane-based foam insulation steel pipes in the 1930s, they have rapidly developed as an excellent thermal insulation material. Their range of applications has become increasingly broad. Due to their simple construction and significant energy-saving and anti-corrosion effects, they are widely used in various pipelines for heating, refrigeration, oil transportation, and steam transportation.
The overhead tin-foamed insulated steel pipe features light weight, high strength, thermal insulation, sound insulation, flame retardancy, cold resistance, corrosion resistance, water repellency, and easy and neat construction. It has become an indispensable material for thermal insulation, sealing, and other applications in industries such as construction, transportation, petroleum, chemical, electric power, and refrigeration.
The steel jacketed steel steam delivery insulation pipe is composed of an outer protective steel pipe with steel pipe anti-corrosion, a polyurethane foam insulation layer, and an inner working steel pipe.
