Hebei Wholesales Threaded Flanges, High-pressure Flanges, Carbon Steel, 20*10 / 40*10 / 80*10 / 100*10

Flanges supplied for joining, sealing, transmitting and supporting machine and structure work. The range covers 6 options, built in Carbon Steel, and each option is priced separately so the cost can be matched to the job rather than averaged across the range. Made by a verified 1688 maker.

Flanges: Overview

This listing covers 6 options of flanges, and every option is held in stock so a single unit and a repeat order ship from the same batch.

The working parts are made in Carbon Steel, which is what decides how the item behaves in service rather than how it looks on the shelf.

Buying direct from the maker keeps the price at trade level and keeps the door open for bulk cartons and OEM branding on the same item.

Key Features at a Glance

• 6 options – sizes and grades to suit different duties, all priced separately.
• Carbon Steel – chosen for the working parts, not just the finish.
• Sizes 20*10 / 40*10 / 80*10 / 100*10 – the common sizes are covered without a special order.
• Trade supply – single units and bulk cartons from the same production batch.
• OEM and ODM – custom logo and custom packaging available on request.
• Export packing – boxed for shipment and cartoned for pallet or container loads.

Using Flanges

Matching the item to the job

Start from the joining, sealing, transmitting and supporting machine and structure work you actually do, then choose the size and the grade from the table above. Buying the heaviest option for light work costs money on every order, and buying the lightest option for heavy work costs more in replacement.

Where the range offers several sizes, keep one of each common size in stock rather than several of the one you use most. The second size is what saves a second delivery.

Working practice

Set the item up square and tight before work starts. Most of the damage reported on flanges comes from starting a job with something loose or misaligned rather than from the load itself.

Work at the speed and the feed the material allows. Pushing harder to save a minute is what shortens the life of the item and spoils the finish at the same time.

Buying and Care

Buying in quantity

Prices fall with quantity, and mixing sizes in one carton is normally possible. Tell us the sizes and the split you want and we will quote the carton and the pallet.

For repeat business a sample order first is the cheapest way to confirm the grade, the finish and the packing before a container is booked.

Storage and upkeep

Keep fittings dry and lightly oiled in store. Threads and machined faces that are allowed to rust will not torque down to the figure they were made for.

Fit with the correct size of key or spanner and torque to the figure the joint calls for, rather than by feel.

Available Models and Prices

All options are in stock unless marked otherwise. Prices are per unit in USD; carton and pallet prices on request.

Where It Is Used

Machine building and repair, pipework and process plant, structural and civil work, vehicle and agricultural equipment, and general industrial maintenance.

Choosing Flanges

1. Match the thread, the diameter and the pressure or load rating to the drawing first. Material and finish then decide how long the part lasts in the environment it works in.
2. Check the size and the quantity against the job before ordering, and ask for a sample where the grade is not obvious from the photograph.
3. Allow for spares on the sizes you use daily. A second unit in the van or the store is cheaper than a lost day.

Care and Maintenance

Keep fittings dry and lightly oiled in store. Threads and machined faces that are allowed to rust will not torque down to the figure they were made for.

Fit with the correct size of key or spanner and torque to the figure the joint calls for, rather than by feel.
