What raw materials can Ruitu bromine extraction systems process?

Our bromine extraction systems are designed for seawater, bitter brine, salt lake brine, oilfield water, bromine-bearing industrial wastewater and concentrated brine from desalination plants. The process route is selected only after we review a laboratory analysis of your feed.

Do you supply single machines or complete plants?

Both. We supply individual machines such as salt washers, roller crushers, dryers, vibrating screens, belt conveyors and hot air furnaces, and we also deliver complete turnkey lines under an EPC contract.

What is included in your EPC service?

Water quality testing, site selection support, process design, project launch preparation, equipment manufacturing and procurement, packing and shipping, installation and commissioning, operator training, finished product production guidance, and output buy-back or decommissioning support where agreed.

Can your salt washing equipment produce food-grade salt?

Our salt washing machinery is used for both food-grade and chemical-grade salt. The achievable grade depends on the crude salt composition and the standard that applies in your market, so we design the washing, crushing, drying and screening stages around your target specification.

How do you support overseas installation?

Our engineers can be dispatched to site for installation and commissioning, train your operators, and stay involved until the line produces finished product at the designed daily capacity.

How do I start a project with Ruitu?

Send us your raw material analysis, target daily capacity, product specification and site information by email or phone. Our technicians will prepare a preliminary budget estimate and an economic benefit analysis based on your budget and expected output.

Product Description

Core Overview

PTFE Lined Elbow is a corrosion-resistant pipe fitting widely used in chemical, pharmaceutical, metallurgical, and environmental protection industries. It features a PTFE lining inside a carbon steel or stainless steel shell, combining the corrosion resistance of PTFE with the mechanical strength of metal, making it ideal for transporting corrosive media such as acids, alkalis, salts, and organic solvents.

Core Advantages

Advantage Category	Specific Content
Corrosion Resistance	PTFE lining can resist corrosion from most acids, alkalis, and organic solvents, with a corrosion resistance coefficient of up to 0.99
Low Friction	The friction coefficient of PTFE is only 0.04, which reduces the resistance of fluid transportation and saves energy
Temperature Resistance	Can work stably in the temperature range of -200℃ to 260℃, suitable for high and low-temperature environments
Non-Stick Property	The surface of PTFE is non-stick, which prevents medium deposition and facilitates cleaning
Long Service Life	The service life is 3-5 times longer than that of ordinary pipe fittings, reducing maintenance costs

Frequently Asked Questions (FAQ)

QWhat is the main function of a PTFE lined elbow?

It combines the high mechanical strength of a metal shell with the superior chemical inertness of PTFE lining to safely convey highly corrosive fluids like acids and alkalis.

QWhat are the standard angles available for PTFE lined elbows?

Standard configurations are 90° and 45° elbows, while custom angles such as 30° and 60° can be manufactured upon request.

QWhat inspection methods are performed to ensure quality?

Each elbow undergoes strict hydrostatic testing for structural integrity and a 5 kV spark leakage test to ensure complete lining continuity without pinholes.

QWhat materials are used for the outer shell?

The shell is typically fabricated from carbon steel (Q235B, 20#) or stainless steel (304, 316L) depending on operating and environmental demands.

QHow does the non-stick property of PTFE benefit pipeline systems?

The ultra-smooth, non-stick surface prevents medium scaling and sediment accumulation, which minimizes flow resistance and simplifies pipeline cleaning.
