Frequently Asked Questions
If you cannot find the answer to your question in our FAQ, you can leave us a message at any time, and we will reply to you as soon as possible.
How are the products packaged and shipped?
In terms of packaging, steel pipes are usually bundled with steel strips and wrapped with moisture-proof plastic film; pipe fittings are packed in wooden or cardboard boxes, with foam and other cushioning materials inside to ensure they are not damaged during transportation. For transportation, we cooperate with multiple professional logistics companies and can choose sea, air, or land transport according to your requirements. The specific transportation method depends on the weight, volume, destination of the goods, and your time requirements.
How is the product price determined, and is there room for a price reduction?
The product price is determined by factors such as the comprehensive cost of raw materials, the complexity of the production process, and market supply and demand. The quotation we provide is very reasonable. While ensuring product quality, if your order quantity is large, we can offer a certain quantity discount; or long-term cooperative customers can also enjoy special discounts.
We want to customize products. Can you manufacture according to the specifications we provide? How long does the customization process take?
We have strong custom manufacturing capabilities and can produce according to the specifications you provide. The time required for the customization process depends on the product specifications and quantity, generally taking 4-6 weeks. You can provide us with detailed specifications, and we will offer you a more accurate timeline.
What international certifications do your products have? Do they comply with our country's safety standards?
Our products have passed international standard certifications such as ISO 9001 Quality Management System certification and CE certification. Please inform us of your country's specific safety standard requirements so that we can confirm whether our products comply.
What are your payment terms? What shipping methods do you accept?
Our usual payment terms include T/T with a 30% advance deposit, and the balance paid upon receipt of goods. We also accept payment by irrevocable letter of credit. For shipping methods, we can provide FOB, CIF, etc., and specific arrangements can be made according to your requirements.
In municipal pipeline construction, how can damage to other underground pipelines be avoided?
Before construction, check the underground pipeline drawings and use a pipeline detector for positioning; during excavation, use manual test pits (avoid blind mechanical excavation), set up warning signs, and arrange for dedicated personnel to supervise.
Drain pipe blockage, quick unclogging methods?
For mild blockages, use a drain cleaner (spring type, pneumatic type); for grease blockages, pour hot water + baking soda + white vinegar (reacts to dissolve grease); severe blockages require dismantling and inspecting the pipes to remove foreign objects (such as hair, debris).
What are the possible causes of a sudden drop in pipeline pressure?
Common causes: pipeline leaks, pump body failure, valve not fully open, sudden increase in water usage at the end point; troubleshooting sequence: first check the valve status, then measure pipeline pressure, and finally locate the leak point or repair the pump.
How to solve rust and corrosion in metal pipes?
Mild corrosion can be treated by rust removal followed by applying anti-corrosion paint or galvanization; severe corrosion requires pipe replacement; for long-term protection, anti-corrosion pipes (such as stainless steel pipes, plastic-coated steel pipes) can be used, or lining can be applied inside the pipes (such as epoxy resin lining).
How to prevent and handle pipe freezing and cracking in winter?
Prevention: Expose the pipe wrapped with insulation cotton and maintain water flow inside the pipe (such as a small flow at night); Treatment: First thaw (slowly pour warm water, avoid open flames), then check for cracks, patch small cracks, and replace pipes for large cracks.
Scaling on the inner wall of the pipeline affects the flow rate. How to deal with it?
Physical methods (using pipeline cleaning balls, high-pressure water flushing) or chemical methods (injecting descaling agents such as citric acid or hydrochloric acid solution, with the choice of agent depending on the pipe material); for long-term prevention, filters can be installed and regular flushing performed.
